The Ariens 1960's and 1970's 
  Sno-Thro Photo Archive .    

PROUDLY MADE

IN THE U.S.A.
 




The 1960's and 1970's Sno-Thro photo archive! 
 

When I started this page, it was going to be very simple and basic.. just one page,
a small look at my machine and some information I have discovered about it.

But then.. I kept finding so much interesting info on-line, people posting questions, posting photos and youtube videos of their beloved machines, (often passed down from father to son),  that I thought a more in-depth webpage might be fun and informative! So I started asking some of the guys I came across on-line if I could post their photos here, perhaps as an
"identification guide" to the early models, and as a place for people to show-off their machines too, if they wish..I would like to create a page that is informative and interesting for owners
and fans of these early Sno-Thros..   

Im not interested in recording EVERY Ariens model ever made! 
that would be far too large of an undertaking..
so lets make the cut-off around 1979 or so, the first two decades, 1960's and 1970's,
just to keep it managable.

(update! originally I did plan to only focus on 1960's and 1970's models..but I have now included *all* Ariens Sno-Thro models! just for fun...but the primary focus of this webpage
will still be the older machines.)

If you have one of these Sno-Thro's, and would like to share a photo (or two or three) here
on this page, please send it in! you will get full credit for your photo of course, and maybe you could give us a brief description of your machine! Im sure it would be of interest to many..

And if anyone has any information about the names and dates of the different series, phase transitions, models in a series, that kind of thing..I would love to hear it! (and share it!)

thanks..

First Series of Ariens Sno-Thros, 1960 - 1964.

 









First Series

1960-1964
The first five years of Sno Thro production.

It seems there is no official "series name" for these 1960-1964 machines,
(like there is for the later "10,000 series", "22,000 series" etc..)
Because they were the first, they were simply called the "Ariens Sno-Thro" line!
So we just have to call them "First series" to differentiate them from the later series.

The 1960 manual lists a "4-1/2 H.P. Lauson winterized Engine"
Tecumseh took over the Lauson company in 1957, and for a few years after engines still
wore the Lauson name. The earliest sno-thro's have engines that say "Lauson-Tecumseh"
also, the 1960-1964 "first series" machines all have a "L" in the model name, (except for model 10M, which may have been the first model) the L is presumably for Lauson.

These "first series" machines have only one clutch control lever, that turns on both the transmission to the wheels *and* the auger/impeller drive, there are not seperate "tractor clutch" and "sno-thro clutch" levers like there are on the later 10,000 series.

This "first series" has the distinctive "half round" bucket shape, unique to this series,
some also have a "rotor shield" added to the front, attached to the "half round" bucket,


 "Sno-Rotor Shield Kit, No. 4-10M"
Came standard on the 1961 10M-L55, and could be ordered as an option for the 10M-L35.


The "half circle" bucket shape was used the first three years, 1960, 1961 and 1962.

For 1963, the bucket shape changed, and now, rather than a "half circle",
it becomes a "half teardrop" shape:

This "half-teardrop" bucket shape was used on the 1963 and 1964 First Series models, It was the precursor to the "full teardrop" shape that would come along in 1965 for the first year of 10,000 series production. This half-teardrop bucket is therefore somewhat rare, being used on only two model years, 1963 and 1964 "First Series" models.

So there are three distinct features of "first series" 1960-1964 machines, that are unique only to this series:

1: The "half circle" or "half teardrop" bucket shape, with or without optional "show shields"
2. Only one "clutch control lever" which turns on and off *both* the transmission and augers.
3: The first series "rounded chute", also unique to this series.


 

Known models in the "First Series", Seven known models across 5 years:

10M
10M-L35
10M-L55
10M-L60
10M-L60D
10M-L60DT (tractor only)
10M-L40


1960:

10M  -  Believed to be a 1960 model - 24" scoop,  4.5 HP Lauson Engine.
(it is confirmed that the 4.5hp engine was used in 1960, however there is no known data that actually specifies any model numbers for 1960!, only the 4.5hp engine is specified for 1960) But based on features of the 10M, its very likely that model 10m is the one and only 1960 model.


1961:

10M-L35 - Known 1961 model - 24" scoop, 3.5HP "Winterized Lauson" Engine.
10M-L55 - Known 1961 model - 24" scoop, 5.5 HP "Winterized Lauson" Engine.


            
1962:

10M-L35    - Known 1962 model - 24" scoop, 3.5HP Techumseh "Snow King" Ezee Start engine.
10M-L55    - Known 1962 model - 24" scoop, 5.5 HP Techumseh "Snow King" Ezee Start engine.
10M-L60    - Known 1962 model - 24" scoop,    6 HP Techumseh "Snow King" Ezee Start engine.
10M-L60D -  Known 1962 model.- 24" scoop,    6 HP Techumseh "Snow King" Ezee Start engine.


1963:

10M-L35 - Known 1963 model - 24" scoop,   3.5HP Techumseh "Snow King" Ezee Start engine.
                     1963 is the first year of the "half teardrop" scoop, while 1960, 1961 and 1962 have the "half circle" scoop.

10M-L60  - Known 1963 model - 24" scoop, 6HP Techumseh "Snow King" Ezee Start engine.
                       (can not take attachments, unless modified with "No. 8-10M Ratchet Wheel Kit)

10M-L60D - "D" for "Deluxe"  - Known 1963 model,  first model that can take attachments in the
                         "Gard-N-Yard"  attachment line.
- 24" scoop, 6HP Techumseh "Snow King" Ezee Start engine.
                          Has "Ratchet Drive" and "Ratchet Wheel Differential" (possibly this actually started with the
                         1962 10M-L60D? uncertain at this time.)
            
10M-L60DT - "DT" for "Deluxe Tractor" - a1963 Tractor Unit, first Tractor Unit sold as a seperate unit,
                             that can take attachments.
Has "Ratchet Drive" and "Ratchet Wheel Differential"
                            (this is the same tractor unit that comes with the model 10M-L60D Sno-Thro)
                             Only two attachments, the 30" reel mower, and the Lawn Vaccum, were available with
                             the 1963 "Gard-N-Yard" line. This was a precursor to the later "Trac-Team" line
                             that would come along in 1965 with the beginning of the 10,000 series, and offered
                             many more attachments. (more detail on next page.)


1964:

10M-L40 - Known 1964 model,  4HP.

10M-L60D - Probably a 1964 model.
10M-L60DT - Probably 1964 model.

(there is a confirmed 6hp model in 1964 (see bottom of this page) but its exact model number is not mentioned.      


      
There are probably model numbers missing from the list above! These are only the known models so far, there is no known "all-time" model list for the first series. I have gradually compiled the list above as new research and information continually comes in, and it is all subject to change! ;)

First Series Accessories and attachments:
(Gard-N-Yard attachments could not be used with 1960, '61 or '62 Sno-Thro's..only the
1963 and 1964 "Gard-N-Yard" labeled machines could accept the different attachments.)

No. 1-10M  - Tire chains  for 3x12 semi-pneumatic tires, available by 1961.

or 1963 10M-L60DT Tractor Unit.

No. 44-10M - Reel Mower Attachment. Can be used with 1963 10M-L60D Sno-Thro
                          
or 1963 10M-L60DT Tractor Unit.


In 1960 and 1961 the engines are referred to as "Winterized Lauson" engines.
(Techumseh bought the Lauson company in 1957)
beginning in 1962, the engines are called Tecumseh "Snow King" Ezee Start engines.

It would appear, based on what we know so far, that only the 1963 and 1964 Sno-Thro models were part of the Ariens "Gard-N-Yard" line of interchangable attachments. And they appear to be the only Sno-Thro models that had the "Gard-N-Yard" logo on the white nameplate:





The earlier 1960-1962 machines could not take attachments,
(the white nameplate on the earlier machines does say "another Gard-N-Yard tool"..but that only means the Sno-Thros were a part of the overall "Gard-N-Yard" line, but they could not take attachments, they were a Sno-Thro unit only. (The whole "Gard-N-Yard" line included lots of non-snow related machines, such as garden tillers and etc.)

In the 1965 the 10,000 series was introduced, and instead of the "Gard-N-Yard" attachment line, the new line of interchangable attachments was now known as the "Trac-Team" line..

This makes the 1963 and 1964 "Gard-N-Yard" Sno-Thros rather unique models in ariens snowblower evolutionary history.

Some 1960 model 10M part numbers..thanks to Michael Y for digging these up:
"Belt number is 07204700. Tires are still available but are very expensive. Contact your local dealer for pricing.
Tire number is 07102800 and rim is 07103800. They will not be hard tires. They will be pneumatic."

1960


Update, October 2010.
Eureka, I believe I have discovered the 1960 Sno-Thro! 

When I started this webpage I believed that the only models available in 1960 were:

10M-L35  -  24" scoop, 3.5HP Techumseh "Snow King" Ezee Start engine.
10M-L55  -  24" scoop, 5.5 HP Techumseh "Snow King" Ezee Start engine.

I based those 1960 models on the information in the reproduction brochure that came with the die-cast model of the 1960 ariens snowblower (see below for photos of the model)

When I started this page in January 2009, I simply didnt know enough about features on these early machines, and how to glean obscure clues from manuals and brochures. (and I didnt have all the manuals and brochures back then, that I have now, thanks to all the Ariens owners who have shared information with me!) It seemed a logical conclusion at the time, and I never even questioned it!..but further research has now shown its probably wrong.

It turns out that the small reproduction brochure that came with the die-cast model is not actually 1960 information! it is actually a hybrid of 1961 and 1967 information, the front and back covers are form ST4-61, from 1961, and the inside is 1967 10,000 series information!  There is no 1960 data in that brochure!

It is believed that Ariens simply does not have any 1960 model information!  (or very little)
(it has been 50 years, and things do get lost over the years..)
I have asked! as have others..Ariens always sends regrets that they have nothing to share.
(and Ariens is always very willing to share! they are very helpful with anything and everything they can possibly help with, in fact, most of the historic manuals are hosted by Ariens! on their own webpage, as a service to their customers.)

But lacking specific 1960 information, it seems they created the brochure for the 1960 die-cast model with the oldest information they had available, which happened to be 1961. But I now am convinced that the actual 1960 sno-thro was *not* the same as the two 1961 models! More data has come to light to show this.

The main external clue to identify a 1960 model is the location of the
"positive shift lever" 
(Shift control lever), which on the 1960 10M is located between the handlebars, with only
two forward speeds, plus reverse.



Based on all currently known information, it would appear that 1960 was the only model
year to have the shift lever in this position!

Also, it would appear that the 1960 10M has a completely different transmission from 1961 and all later sno-thros! it did *not* have a Friction disk drive!
It has a 2-speed geared transmission, no friction disk. (see photos below!)

The shift lever location, combined with the 2-speed "gear transmission" drive system, make the 1960 Sno-thro quite a unique machine! Quite different from all other subsequent sno-thros.

Then, after only one year, beginning with the 1961 model year, the shift lever was mounted on the handlebars, in the "traditional" manner, and these models also had the well-known 4-speed friction drive, which is still in use today.

click here for 1961 diagram.

(note that it is still techinically possible that models 10M-L35 and 10M-L55 existed in 1960!
although I doubt it..but just because the two known 1960 documents do not show them, does not 100% prove they didnt exist..sometimes manuals are for just one, or a few models, but dont necessarily list *every* model for that year! however it seems quite likely that if a 1960 owners manual *and* a 1960 advertisement *only* mention the 4.5hp engine, then its very likely that was the only engine availble in 1960..not 100% proven, but it seems highly likely..and there is also no known 1960 documents that mention them..so I am concluding, for now, that its very likely model 10M was the one and only 1960 model!

Also, considering the 1961 dealer brochure shows models
10M-L35 and 10M-L55 with the
"positive shift lever"  (Shift control lever) mounted on the handlebar, with 4 speeds, and these models have a drive disk and a drive plate ("Friction Disk" drive) (visable in the 1961 brochure) (which the 1960 10M does not have!) this also supports the conclusion that the 10M was a unique model, without a friction drive, and only available in 1960!

There is also evidence that the 4.5 Horsepower Lauson-Tecumseh engine was used in 1960, but *not* in 1961 or later! Two 1960 ariens documents specifically mention the 4.5HP engine.
The 1960 owners manual, form STPL-1060.


And a 1960 brochure, form ST-660 , also specifically mentions the 4.5HP engine,
and no other engines!

Ariens form ST660, 1960 dealers brochure.
Ariens collection, from the Ariens facebook page, used with permission, thanks!



Then, the one known 1961 brochure specifically mentions the 3.5 and 5.5hp engines,
but *not* the 4.5 hp engine! And all later known owners manuals and brochures also
do *not* list a 4.5hp engine.

We also have data that shows Lauson-Tecumseh did in fact offer the 4.5hp engine in 1960:

Lauson_H45D-HB45D-H55D-HB55D_IPL.pdf
5-page Lauson parts list, with diagrams, for engines H45D, HB45D, H55D, HB55D

dated October 1960. (email me if you want a copy!)


All of this data combined strongly suggests the 4.5 engine was only used in 1960, plus the features of the 1960 model itself, the drive mechanism and the lack of a friction disk,
all point to a very specific 1960 Ariens Sno-Thro:

- Model 10M
- with a 4.5hp engine (seen no where else)
- shift lever mounted between the handlebars (seen no where else)
- geared transmision, and no friction-disk drive. (seen no where else)

I would like to thank Gary D., James W., Ted H., who's email dialogs with me,  and sharing of photos, manuals and information, has led to this breakthrough in 1960 identification!   thanks!

1960

And here we have an actual 1960 Ariens Sno-Thro!
This machine is owned by Michael Y. of Lima, NY.

Lima is close enough to me that I was able to drive down to meet Mike and check out his 1960 Ariens in person! This machine belonged to Mike's grandfather, was last used about 10 years ago, was stored in a barn, and the barn actually collapsed on top of the snowblower!

In November of 2010, Mike rescued the machine from the remnants of the barn, and decided to get the old girl up and running again! (and this is the 50 year anniversary of this machine!)

Mike took these first three photos the day he dragged the machine out of the collapsed barn:







she is looking rough, but she is complete, and was operating when she was stored away 10 years ago..Mike is confidant he has the know-how and skills to get her up and running again!

On November 25, 2010 Mike invited me to stop down to see the machine in person! and we took a detailed look at the machine and it's inner workings. As I discussed above, the 1960 Sno-Thro has a unique drive mechanism, a geared 2-speed drive. (2 speeds forward, one speed reverse) This drive system was unique to the 1960 model 10M only, and during the second year of Ariens sno-thro production, 1961, the drive was changed to the well-known friction disk drive, which is still in use today.













And here are the photos of that unique 1960 drivetrain:
(the machine was actually laying on its side when I took these photos, but I rotated the photos
to "service position" since people are most used to viewing a machine in that position)









The drivetrain was well oiled when it was stored away 10 years ago, so things in are good condition..the pink fluffy stuff is the remains of a mouse nest! which a mouse had made from fiberglass insulation, so apart from a little cleaning, things are in good shape overall.

And here is a comparision between the 1960 transmission with a more common "friction disk drive" machine, in both cases, the large pully at the bottom is for the belt from the engine,
but that's where the similarity ends!




After several work sessions and quite a few repairs to several different areas, Michael got the machine to fire-up and operate! He actually used the old girl to clear some snow on
December 6, 2010. Not bad for a 50 year old machine!






The Ariens tag is missing from Michael's machine, so we dont know the serial number.
but based on the engine tag:

H45D-2077P
9746365

We can conclude that Michael has the *oldest known* Ariens sno-thro!
(The engine serial number is lower than the other 1960 models shown below)
and not only is it the oldest known Ariens Sno-Thro, it is now also the oldest known *operating* Sno-thro as well!


For more photos and details on Michael's restoration, check out his photo album.

Thanks Michael!
its great to see a 1960 Sno-Thro still doing what she was designed to do!

 

 


1960

Check out this beauty!
a 50 year old Ariens Sno-Thro! in basically original condition, still in use!

This was the first 1960 model 10M on this webpage, and this is the machine that led to the
identification of the 1960 model, which was not conclusively known when I started this
webpage.

Ted H. of Nebraska emailed me his photos, and shared some information about his machine..Ted says:

Scot,
I have an Ariens Sno Thro that I keep out in my hanger at the airport and keep it up so I can use it there if necessary, (or anywhere else if needed for that matter).  I have other snow blowers but this one still works well and although don't use it that much, starts quite easily and does a good job of throwing snow.  My father had it in his business years ago, and after he retired it eventually migrated to me.  It think it was used quite a bit.  In the late 70's/80's I used it at my residence.   

I was fiddling with it today and decided to see if I could find out more about it.  Actually I wanted to check the grease in the rear gear box and seem to recall doing it years ago, but appears that it is somewhat difficult to access.  The front one has a seal that apparently leaks a little but that is an easy refill.  Anyway, I came home and dug out the information.  I noted that it had a Lauson Engine, although it says Tecumseh.  It's a 4 and 1/2 horsepower and has serial number 000635.  Was curious as to year also and thought probably late or mid 60's.  Got on your web site and bingo, the manual and information match were interesting.  Apparently 1961 manufacture, which was the year I graduated from college.  As I indicated it runs well, haven't done much to it but change oil, keep the front gear box full, and run it once in a while.  Think I changed the belt on it 10 or 15 years ago as it looks pretty good.  Also have replaced a shear pin or two some time back, and not too long ago, the allen screw(s) on the jaw coupling came loose and had to tighten that/them up.  Normal routine kind of stuff.

Machine was purchased originally for use in a business, I suspect for clearing the driveway area around a service station and possibly sidewalks.  In the mid to late 70's to late 80's or early 90's was utilized around residence and residential areas, having been passed to me subsequent to the retirement of my father, the business owner.  Finally it was stored primarily at the airport in an aircraft hanger for use either in town or to plow snow away from the immediate area of a hanger door, clearing the way to where motorized snow plows are utilized.  The latter is now its primarily function.  Its life has been in Nebraska and it has required very little maintenance.  It's obvious that before I came in possession of it, one of the impellers was damaged some way, as it shows signs of being welded.  It did not, however, seem to effect the balance, as it runs true and well.  I think I did change a belt on it a few years ago and have replaced shear pins.  Also had the set scew or screws on the jaw coupling come loose some time back and had to tighten.  Other than that, changing the oil as I felt necessary, or adding some air in the tires every few years, has pretty much taken care of it.  Admitedly, I haven't used it too much lately, but when I start it up, its ready to go to work.  Good thing, since after 49 years or so I suspect any warranty has expired.

You've got a real labor of love with your web site and appreciate the information I got from it.  My Ariens sure speaks well of their quality.  

 Ted H. (Western Nebraska)









(notice the engine label says Lauson-Tecumseh)




(Ted's photos are from October 2009)


At first I thought Ted's machine is probably a 1961 model, but based on all the research, (detailed above) I'm now convinced it is in fact a 1960! The second oldest known Ariens sno-thro! also celebrating its 50th year of service in 2010.

Tecumseh engine data:
Model H45D-2077P
Serial - 9818872

Thanks for the photos and information Ted..you have quite the antique there!
 








1960


A scale model of a 1960 Sno-Thro!





(thats my full-size 1971 Ariens in the background! ;)


Its a die-cast model made by TWH Collectibles.
The model came out in 2008, to commemorate the 75th anniversary of the Ariens company.
You can find it on ebay for between $50 and $75..but there is no need to pay that much!
because you can simply order it directly from Ariens for $25!

http://www.theelitegroup-ariens.com/ 
 
The little reproduction brochure is from 1961 on the front and rear covers..
but the interior is clearly early 1970's! which is fine..just something interesting I noticed..


 


 



1960

Here is a third 1960 model 10M!
but this one comes with a twist in its history!



This machine is owned by David N. and he puchased it recently.
Unfortunately the Ariens tag is missing, so initially there was no way to positively identify the model number. But the Tecumseh engine tag remains, and its also a 4.5hp engine, same as Michael and Ted's machines above.  At first I assumed this had to be a 1961 or 1962 model, because it clearly has the later friction drivetrain, (with the shift lever mounted on the handlebar) so it cant be a 1960 right? wrong! 


The two 1960's Snow-Thro's shown above still contain their original 1960 geared drivetrain,
which, as I discussed, is unique to the 1960 model. So it seems logical to conclude that any machine with a friction drive must be 1961 or later..but hold on..

I received an email from "Bob in
Skaneateles" concerning this machine..Bob has helped me before, with some 10,000 series spotting features..thanks Bob!
Bob noticed something interesting about David's machine, which I had completely missed!
Notice this tag still on the handlebar:



What is that? Turns out its the original 1960 shifter tag!



This machine had its original 1960 transmission replaced! but that tag was never removed..the tag is for the original shifter, that was once mounted between the handlebars, as seen in the two sno-thro's above.

Bob sent me an excerpt from an Ariens book from 2008, "Ariens, Kings of Snow" that explains what happened:

“Design began on December 15th in 1959 and by March of 1960, a model was
complete.  As the snow blower was developed, it was tested on every kind of
snow.  It was July of 1960 when the company started production and 1,865 units
were made in the introductory season.

The original Sno-Thro design included a gear driven unit that consisted of a low
and high gear forward and a reverse, which competitors did not have at the
time.  However, the gear-driven transmission caused problems when operators
would try to put it in reverse while moving and this would cause the gearbox to
fail.  To remedy the situation, the company opted to replace the customer’s
gearbox using a disc drive unit that is still in use today.  The cost of the
replacement parts and warranty caused a significant financial impact on the
company that year, but the Ariens Sno-Thro has gone on to become one of the most
successful product lines in the history of the company.”

-excerpt from the book "Ariens, Kings of Snow" published by Ariens in 2008.

So David's machine is clearly one of these 1960 models that had a new transmission installed!
and Michael and Ted's machines above still retain their original 1960 drivetrains, their transmissions were *not* replaced..so now we have examples of both! excellent...

Here is David's 1960 Sno-Thro, with the updated drivetrain. The original geared drive was probably replaced by an Ariens dealer very early in its career, probably in the early or mid 60's.

1960 Ariens Model 10M.
with a replaced drivetrain, but its original engine.
and a shifter tag remaining on the handlebars, giving away its true identity!

Tecumseh engine data:
Model H45D-2077P
Serial -
9755541

Thanks David!

The is still some ambiguity concerning the Tecumseh engine serial numbers on these early machines. On most later Tecumseh engines, a 4-digit number in the serial number is a date code, which is very useful for identifying the year an engine was built (and often the machine the engine is on as well)..but it seems this date code was not yet in effect in 1959 or 1960.
the engine codes on the four 1960 models on this page are:

Model H45D-2077P
Serial - 9746365

Model H45D-2077P
Serial - 9746434

Model H45D-2077P
Serial - 9755541

Model H45D-2077P
Serial - 9818872



So clearly the "2077" is not a date code in this case..its just part of the engine model number.
so that leaves the serial numbers.. I *dont* believe there is a date code hidden in these
serial numbers, they are likely just
consecutive build numbers.
but has anyone ever heard of any hidden code, any meaning, in those numbers??
(could the "9" at the beginning of the serial number possibly mean 1959?)
or are they just meaningless consecutive build numbers? this is still unknown.


 






1960

And here is a fourth 1960 model 10M!
This one is owned by  Jason E. and it also appears to be a 1960 that had its original gear
drive replaced by the updated friction drive..probably another machine that  had its drive replaced under warranty back in '60 or '61.

Again, we have no tractor tag, but the engine pegs this machine as a 1960 model 10M,
because its the original Tecumseh 4.5hp engine, only used on the 1960 model.

The engine model and serial number on Jason's machine is:
Model: H45D 2077P
Serial:  9746434

That serial number is only 69 digits removed from Michael's machine! (the first 10M on this page, seen above) which has serial No. 9746365! those are *very* close serial numbers..the two engines were probably made at Tecumseh only days apart!

But this leads to an interesting conundrum..we can perhaps assume that Michaels machine is the "oldest known"..based only on the Tecumseh serial numbers..but there is really no way to know that for a fact! ;) its unlikely that Ariens put engines on Sno-Thros in consecutive order, (consecutive by Tecumseh engine serial numbers)..and with those two engines only being 69 digits apart, there is no real way to actually know which snowblower is older! If we had Ariens tractor tags and serial numbers, then we could be confidant which is actually older! but we dont have those numbers..therefore "oldest" is simply a guess..not that its really important anyway! its just a fun excercise..but unfortunately there is no way to be absolutely certain..

and..its not even proven that the Tecumseh serial numbers are in fact consecutive builders numbers, that is also a guess. (although it seems likely).. But we do have serial numbers spanning 72,000 digits..Did Tecumseh really make that many engines of the H45D model? perhaps..but that seems like a lot of engines..so there is a lot of guesswork going on to declare an "oldest" snowblower!

But who really cares? ;) because with only 1,865 10M units made in 1960, and all being made within a few months of each other, all these 1960 models are essentially the same age now,
50 years later!


Here are the photos of Jason's machine:

Thanks Jason!

 

 




1960

And here is another "first year" 1960 model, still working fine in its 50th year!
This is a "one family" machine..this machine is owned by Jerry J. of Apalachin, NY,
and was originally purchased by his father in 1960. Jerry's snowblower has *not* had a replacement friction disk transmission, it is still using its original geared transmission.



Here is Jerry to tell us about his snowblower:

Scot,
 
I sent you an e-mail several weeks ago telling you that I would send some photos of my 1960 Model 10M Ariens Snow-Thro.  As I said previously, I also have the 1960 cab that was purchased at the same time.  The Serial number is hard to make out and I can really only see the numbers 309.. 1960 is the year I went off to college and my father purchased this unit at that time (since he had lost my services for the winter).  I have used it sparingly for several winters but this year we had our gravel driveway paved so I decided to use the blower since I was no longer shearing pins due to loose stones.  
 
One of the photos shows the unit in action.  As you can see, the snow was as high as the auger and it performed very well.  As far as I know, nothing has been done to the carburetor and it was beginning to surge and would eventually shut off.  You may be able to see where I rigged the governor to only open so far and this seemed to fix the problem for now.  During the last 18” snow fall in March, I burned out the belt and the auger seized–ups and I thought that was the end of the blower.  After it cooled down and the snow melted off the auger I was able to turn it.  When I looked into the auger gear box it was dry so I put in some gear oil and now if seems to run OK.  I probably had not put gear oil in the unit for 10 years or more.  The photo of my dog was included so you could see the depth of the snow after the last storm.  In that photo I shoveled a path for the dog.
 
The “V” shaped iron bar on the front was put there by my cousin shortly after we got the unit in 1960 and is home made.  We use to live just south of Utica and got a tremendous amount of snow so we used the iron bar to break up the snow when it was higher than the machine.  Apparently the muffler, or what is left of it, was also replaced and when it was we forgot to put the shield back on.  Now the muffler and pipe coming from the head is so old I dare not mess with it.  A photo of the shield is also included and I have all the original paper work.    You are welcome to see the unit and thanks for the site, it is very well done. 
 
Jerry
(March 2011)






Heatshield, removed for photos.





















Thanks Jerry! 
 





1961

I dont yet have any photos of a confirmed1961 machine, but we do have a 1961 brochure!
Beginning in 1961, the position of the gear shift lever was moved to the handlebars, with a four speed friction disk transmission, beginning the standard configuration:



The only manual or brochure from 1961, known so far, is form ST4-61.
This is the reproduction brochure that comes with the die-cast model of the 1960 Sno-thro.
But clearly it is a 1961 brochure that comes with the model!
based on the date of the brochure, and the models shown.
This brochure lists two models for 1961:
10M-L35
10M-L55
 

 




(probably) 1962

Here is a beautifully restored machine to represent the 1962 model year!
Chris L. of Newtown, Connecticut
owns this machine..it was purchased brand-new by his father in 1963 or 1964. (The first of many examples on this webpage of multiple generations owning and using the same snowblower! handed down from father to son..and sometimes even grand-son!)

Chris fully restored this snowblower back in 2004, here is Chris to tell us the story:

Hi Scot,
Interested in pictures of a full frame up restoration of my Ariens?  I restored it on the 40th anniversary in 2004, rechromed handlebars, etc.  Let me know and I"ll send them along.

I made all the decals myself (drew them on AutoCAD, printed them on either clear or white vinyl, then covered them with clear vinyl to protect the color).  I thought it was interesting to find someone as excited about their Ariens as I was about mine.  It is by far the best snowblower in the world.  I wouldn't trade this for anything.  My dad bought it brand new in 1964.  I used it for years growing up to clear all the driveways on our side of the street.  When we built our house, my dad gave it to me, and I cringed for 2 years using it on a gravel driveway.  After that we paved it.  The machine always started on a dime, and ran like a champ, but it looked old.  It had rust, flaked paint, it needed some TLC, and I thought if it's that reliable, if I enjoy using it so much, it should look appreciated.  So I talked it over with my wife, and allocated $300 to restore it from the ground up.  I replaced all bushings, bearings, and seals, and the Ariens dealer down the street used to let me just walk through their parts department picking up old parts, drive disc, shear pins, this odd piece, that strange part.  I called Ariens in Wisconsin because the model number plate was missing, and I got this old guy who answered "Ariens... Parts..."  I said I wanted all the manuals for my Ariens, but didn't know the model or year.  He said "Does it have a round or square shute?"  I said "round."  He said "how many horse power?"  I said "6."  He said "how wide is it?"   I said "24 inch".  He asked "Are there were half circle pieces bolted to the front of the auger?"  I said "Yes."  He said "1964 10ML-60D."  He knew his machines...  Anyway, I asked how much I owed, and he said I could put a check in the mail when I got his package!  Old fashioned service!!!  So, with parts book in hand, I got all the new parts I needed from around the countryside, and set to tearing it apart and restoring it.  Total cost was $305.  Try to buy a snowblower of this quality for $305 today...  I think I did a pretty nice job on the restoration, and it runs like it always has.  Always starts on the 3rd pull.

Only three things that are currently wrong with it:

1)  The electric starter cover is rusted.  It is supposed to be zinc plated, and it'll be too expensive to chrome it, so I leave it off, it's on the shelf in the shop.

2)  The exhaust was changed in the mid 80's from a pipe and can exhaust to the square type, so the shop that did the work for my dad cut the cold weather carb cover to make it fit.  I have another cover, just haven't gotten around to cutting out a chunk of steel and welding it on (wrong year cover so I won't put it on my '64 intact, I'll use a piece of it to fix the old one)

3)  I've followed tag sales all over the place to find an original throttle handle, I just can't find one, so I have a modern "backwards" throttle in place (full forward is off)

I don't mind those three problems...  It makes me think of my dad when I use it, and that's fine. 

Chris


here are the photos:












Thanks Chris! beautiful job on the restoration!

Chris had assumed his machine was a 1964 model..but with a lot of emailing back and forth, we have come up with a theory that I believe pegs it as a 1962 model..
Chris's snowblower does not have its original engine..his dad replaced it back in the 80's.
So we dont have a tecumseh engine tag to date the machine..but Chris's cousin also bought a snowblower on the same day as his Dad, and Chris still has that engine! it has a tecumseh serial number of 2334, which means "the 334th day of 1962" which is December 1, 1962.
Thats the date the engine was assembled at Tecumseh..This would make the snowblower a very late 1962 model..perhaps assembled in early 1963, just before snowblower production ceased for the season, and the plant switched over to lawnmower production. Chris also has a Tecumseh engine manual, that came with his snowblower when his dad bought it, that says "revised July 1963"..which would mean his Dad had to have purchased the snowblower after July 1963. My theory is that Chris's snowblower is a very late 1962, built in December 1962 or January 1963 (either way, it would still be a 1962 model) and since it was built so "late" it probably didnt sell that winter..it had to wait until the following autumn to be sold.
So then Chris's father purchased the machine in the late summer or autumn of 1963, (when it was still brand new and only a few months old) which fits the "revised July 1963" notice on the tecumseh paperwork. Chris also has the original manuals that came with the machine!
It came with both a 1962, and a 1963 manual! Forms ST-62-I-R and ST-63, which also supports the theory of "a 1962 model bought in the autumn of 1963" or perhaps even early 1964.

Another reason I believe this is a 1962..So far all known evidence shows that the "half-circle" scoop was only used in 1960, 1961 and 1962, and the "half teardrop" was used on 1963 and 1964 models..this also strongly suggests Chris' machine is a '62. Although this is not 100% carved in stone! Chris has always believed it was a 1964 model, and it might be! but for now, all evidence seems to point to 1962. But this is all still a very imprecise science! ;)

 
 



1962

Here is another 1962 model, from a 1962 brochure!
thanks to Chuck M. Here is an illustration of a 1962 Model 10M-L60:



The full page scans of this brochure are on page 11.
 





1963

1963 Ariens model 10M-L60D

Beginning in 1963, the bucket shape changed, and we now have a "half teardrop" bucket shape,
believed only used in 1963 and 1964.

I found some photos here, of a nice 1963! 

I emailed Rob asking him if I could use his pics here on this page, he said sure!
and told me some more about his machine..thanks Rob!

Rob's 1963 was bought new by his Dad at Sears in 1963.
being a 10M-L60D, it originally came with a 6HP engine, but Rob says his recieved a
7hp engine at some point in the past. It originally came with the short "rounded chute" and
Rob's Dad later added the home-made "chute extension" visable in the photos.

Rob inherited the machine from his Dad, and spruced her up in 2008. He found a "tractor body" in excellent shape and installed it, and painted up the engine. Looking good and still
working great after 46 years!

Here is Rob's 1963 before the "fix up":


 

 And after recieving the new tractor body and repainting of the engine:

Thanks Rob! 

 


 


1963

And here is another set of photos of another vintage 1963 10M-L60D machine.

This machine is owned by Chuck M. of Walpole, Massachusetts, who emailed me these great pics..Chuck's machine was also bought brand-new by his parents, and has been in continious use for over 45 years!

"This Ariens was purchased new by my parents in the 60s.  It has been through many a snow storm.  It was not only used to clear the driveways and walkways of our house and the neighbors but my father would create a huge snow pile in the backyard so we could have a hill to sled down ... way cool.  Aside for the shear pin or 2 that has broken this machine is still going strong.  I guess they would never want to create great machines like this - they would not sell many once people buy one - 40 years and still going - what a machine."
- Chuck






(photos from 2009)


Chuck also has two original dealer's brochures that came with his 1963 Sno Thro!
His 1963 model came with a 4-page 1963 brochure, and an older 2-page 1962 insert as well..
check out Page 11 for scans of the brochures..


Thanks Chuck! 
 


  



1963

And here is a third 1963 Sno-Thro, this one is a 10M-L60,
owned by Tom H. of Western NY.



Tom did an engine swap on this machine, replacing the original Tecumseh with a new
Briggs & Stratton engine. The engine swap is detailed on page 9.

 



  



1964

Here is a drawing of a 1964 model 10M-L40.




The 4hp 10M-L40 was a new model for 1964, and has its own owners manual.

There is also a known 1964 6hp model, but the exact model number is not confirmed,
although it seems likely it was a 1964
10M-L60D and/or 10M-L60DT

There are three known 1964 documents:
1964 Owners Manual - Form st4-64.pdf
1964 model 7-10M sno-thro attachment. (47001-68000)  - Form SSA-64.pdf
and form 6464S, which is my 1964 dealer brochure:





It shows a snowblower with obvious first series features, and does mention a 6hp model, but does
not mention any specific model numbers.

 







1964

And here is a 1964 model 10M-L40!
This is the 5th and final year of "first series" production.

This machine is the first of many on my webpage where the snowblower has remained in the same family for three generations! Originally purchased new by the current owners Grandfather, then passed down to the son, then passed down to the Grandson!

This machine is owned by George S. of Pittsburgh, PA, and his grandfather purchased the machine brand-new in 1964! Here is George to give us the background story:

Dear Scot,

My grandfather purchased this Ariens Sno Thro in 1964.  He used it until 1972.  My father used it until 1994.  I have had it since then.  It has always been kept in a dry garage, so almost no rust.  Most of my maintenance has been with the engine, which always seemed to need work.  After our huge storm last February, the engine finally gave out.  Mechanically the unit is almost as new as in 1964, since it has only been used a few times each year (if at all) with our mild Pittsburgh winters.  After finding your website, I decided that replacing the engine was a good idea!

After months of searching, I found a new H40 engine with the same dimensions as the existing H40.  I sold the old 4HP engine on eBay for a $50 profit. 

I bought the new engine from Small Engine Warehouse.  It is a 5.5hp Tecumseh Engine ES Snow King LH195SP-67514. It is an H40, just like the original engine.  I did not want to modify the chute control rod, so took care to be sure the new engine would not interfere with the rod.  This is the reason I didn’t purchase an even higher HP engine for the retrofit.

I drilled out the short studs and used stainless steel hardware to mount the new engine.  The only issue I had was that the new engine shaft is 7/8" in diameter, versus 3/4" for the existing.  I found a new pulley (Maska) with the correct shaft diameter and also the same outer diameter so to match the same belt speed.  The shaft was about an inch too long, I used a hack saw to cut the excess shaft off to allow the belt cover to fit perfectly.  I used the existing key to mount the pulley on the shaft.  I added a new belt for $10 to top off the retrofit.

As I cleaned, oiled and greased the Sno Thro, I kept noticing the worn out old solid rubber tires.  I decided to replace the tires while I had the tractor on the bench.  I bought two tires for $50 that included the rim and the correct (3/4") shaft diameter.  The first wheel I pulled came off very easily.  The other wheel REFUSED to budge!  I tried heating it, penetrating oil and prying with a crow bar.  It did not budge!  I used my Dremel tool to grind through the wheel tube in order to remove the shaft key.  I accomplished this......but the wheel still would not move!  Finally, I ordered a new shaft, gear, bearings, etc...for over $100.

After ordering the new shaft assembly, I decided to take one last crack at removing the wheel.  I drilled and sawed through the wheel rim, which is sheet steel, in order to remove the wheel.  After I freed the wheel, I had the wheel tube to deal with alone...basically a tube on a solid shaft.  I used my Dremel tool to cut along the keyway, hoping to split the tube.  I wasn't quite through to the keyway when I heard a POP!  The tube had split on it's own.  I was able to wiggle it off.  I cancelled the shaft assembly order and moved forward!

I drilled 5/16" holes in the existing shaft in order and used Clevis Pins to affix the tires to the shaft.  No problem!

Now I'm ready for snow!  As well built as the Ariens 10000 series are mechanically, I expect this Sno Thro to last another 50 years!

Thanks for your website and please enjoy the attached file with pictures.

I might as well put this here..cant hurt! 
So far I only have the 1971 sno-thro, the machine that led to this entire webpage..
I would *love* to find a 1960 sno-thro to restore!
Im also looking for a 1973 or 1974 10,000 series sno-thro.

And a garden tractor! to restore and use.
an early 60's Cub Cadet, ("original" or Model 70 or 100)
or an early 60's "round hood" Wheel Horse,
or a 1969-1972 Ariens "manorway" tractor.


(I know the manorway is really in the "lawn tractor" catagory..but thats ok.)

I doubt I will ever collect *all* of those, but those are models I would like to look for.
(I will probably only have one tractor..just due to space and money constraints.)
but those are all the models im considering..I would like one nice tractor to do a full restore on!
(or just to use, if its already in good condition.) Right now im leaning mostly toward the
Cub Cadet..but I really like the others too..

The experience of finding and using my 1971 Ariens snowblower, and all the research that has led to this webpage, have really made me appreciate the "Golden Era" of mid-20th Century American-made high quality lawn and garden equipment! The new stuff available in the stores today just cant hold a candle to these classics..Im so impressed with my 40 year old snowblower, that I now want to find a 50 year old garden tractor as well!

So if anyone knows of any of those models looking for a new home, in Western NY,
Finger Lakes, or Southern Tier NY, please let me know!

thanks..
