Can you identify this Allis-Chalmers?

This was my grandfather's tractor, I vaguely remember it. Unfortunately I don't have a better picture.

I'd buy it back if I knew what model to look for.

Someone will probably come along who knows for certain. If not, I'm guessing a C or CA.
I have a similar photo of some of my cousins and myself on a Ford.

We had a model CA when I was a kid, and this tractor looks similar, but not exactly the same. However, many of the relevant clues are obscured by people.

IF I was to take a "guess", I'd say it's a WC.

Thanks guys, I've been comparing this picture to those models mentioned.

I'm leaning towards a CA, because it appears it has the wheels that mechanically extend out, and the linkages that run down the side.

On the CA pictures, I see what I assume to be an RPM gauge mounted off either the steering column, or to a box behind the battery. I wonder what is the difference?

My grandfather's tractor was the tricycle model.

With the left side steering shaft, I think it has to be a CA or C. With the limited picture, I'm not sure what would indicate the difference. I think the WC did not have that steering mechanism.

Katahdin · Jan 28, 2020

In the original picture it's hard to distinguish, but the shaft on the left side is not connected to a steering column. I think maybe it's a linkage for a front lift? Like for a snow plow, which I know my grandfathers did have.

Better picture of a CA:

Edit: Or maybe you're saying, that outside shaft is connected to the steering column through an internal gearbox.

You can't really go by the wheels/rims, different wheel options were available on most all of them.

Easiest way to determine C or CA is how many forward gears in transmission. C is 3 and CA has 4 forward.

Do you realize the CA wheels can mechanically widen with operator in the seat?

Please check 2:25 on this video.

aaaaawww, yea... They are called "power adjust", and it was an AC invention...

BTW, I've owned them...

Is there a chance that one of the other kids in the photo will have more information on the tractor or pictures showing more of it? I'm guessing you're one of them and are related to the rest.
If you ever find out what model it is, please let us know the answer. I'd like to know what it is.

I was thinking the C's had a wide bench type seat, where as the CA's had a pan type seat. But as mentioned above, that may have been an option.

Katahdin · Jan 30, 2020

It was definitely the pan seat, not a bench. Thank you for that detail!

bcp, why did you show the close up of the steering linkage?

Actually the wide bench could also be a B, as some C's had the same wide tractor seat, although a lot of people put "improved" seats on them sold by Monroe. I have B's and C's with the shock cushioned seat.

There is not a doubt in my mind that this is a CA or later tractor. The two items that make this true are the Power Shift wheels, which first came out on the CA and also the traction booster gauge attached to the side of the steering shaft. That also became available with the CA and later tractors.
If you know what year the picture was taken, it might narrow down the possibilities of what the tractor actually is, but my guess is it is a CA.
I just sold off what was left of my entire collection, which included about a dozen CA tractors. Most are still out back while the new owner works out transportation.

I just lightened it as there might be something unseen in the OP picture that would help identify the tractor.

Thank you David and Bruce!

Funny store about my grandfather's "CA." In the 1950s my grandparents were saving up money to add a bathroom and running water to the house, they were still using an outdoor privy and hand pump to draw well water.

Well, my grandfather had his own ideas and took the bathroom money to buy this CA instead.....My grandmother was very displeased!
