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.

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.

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.

several brands
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.
