Ariens 1960's and 1970's
First Series of Ariens Sno-Thros, 1960 - 1964.
When I started
this webpage I believed that the only models
available in 1960 were:
10M-L35 - 24"
King" Ezee Start engine.
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)
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 that it's wrong.
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.
1960 was the only model year to have the shift lever in this position!
Also, 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.
It is also now known 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 two known 1961 brochures specifically mention 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:
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 shows that 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:
- Models 45-10M and 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)
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
breakthrough in 1960 identification!

And here we have
another actual 1960
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
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!)
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:
We can conclude that Michael has the second oldest known Ariens sno-thro!
(The engine serial number is lower than the other 1960 models shown below)
For more photos and details on Michael's restoration, check out his photo album.
its great to see a 1960 Sno-Thro still doing what she was designed to do!

1960 model 10M
a die-cast model made by TWH
1960 model 10M
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.

and a shifter tag remaining on the handlebars, giving away its true identity!
(heat shield removed)
Tecumseh engine data:
Serial - 9755541
1960 model 10M
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
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 "second 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:
Jason's photos are from January 2010.
1960 model 10M
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:
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.

1961 model 10M-L55
Here is an illustration of a '61 10M-L55 from 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 a standard configuration that continues to today:
This drawing is from form ST4-61.

1962 model 10M-L60
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:

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)

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..it is now known that the "half-circle" scoop was only used in 1960, 1961 and 1962, and the "half teardrop" was used on 1963 and 1964 models..So this would have to be a 1962 model purchased the winter after it was built, late '63 or early '64, which is a very common phenomenon which still happens today.

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.
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,

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

Some notes about First Series engines:
There 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 1960 models on this page are:
Model H45D-2077 (1960 Ariens model 45-10M)
Serial - 9724126
Model H45D-2077P (1960 Ariens model 10M)
Serial - 9746365
Model H45D-2077P (1960 Ariens model 10M)
Serial - 9746434
Model H45D-2077P (1960 Ariens model 10M)
Serial - 9755541
Model H45D-2077P (1960 Ariens model 10M)
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.
Update, December 2014: It is now known that this Lauson/Tecumseh serial number type:
Was in use in 1960 on the H45 engines (and likely earlier than 1960)
Then a serial number series:
was in use in 1961 and 1962 on H35 engines, (and likely other engines too)
All of those serial numbers probably do *not* contain a date code! They are likely simply
consecuitive serial numbers.
Then! beginning in 1963, Tecumseh began using the well-known 4-digit date code,
where the first digit indicates a year, and the last 3 digits indicate the day of the year.
In 1961 the engines were called "Winterized Lauson" engines.
In 1962 the same engines were now called "Tecumseh Snow King Ezee Start" engines.
and an "ezee start" decal was added to the 1962 engines, which was not seen in 1961.
This is the only know way to tell a 1961 Ariens from a 1962 of the same model.
I might as well
put this here..cant hurt!
And a garden tractor! to restore and
(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.
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,
