Sears Corn Sheller

[Barnyard]

I have been looking for a sheller for a while. A McCormick-Deering was my first choice but I found a deal on this Sears-Roebuck model. It was electric driven but the motor is shot. Do you think, if I gear down a Cub pto, that a Cub will turn it without making it a candidate for the scrap yard?

2 words come to mind: slip clutch

My two words are: "Jack Shaft".

With proper gearing why not? A cub should be able to handle that sheller at idle so all you would need to do is get close and handle the rest with throttle. Vern

[Tezell]

That would probably be a one of a kind item there Bill.

Go for it.

[Barnyard]

I figured that if an ice cream maker will hold up to a Cub then this should to. Is it overkill? Absolutely, but that's why we have fun with our Cubs.

[Gary Dotson]

I think that one is the same as the one we had on the farm way back when. Bill' have someone crank it, at a pretty good clip, while you check the flywheel RPM with a hand held tach. That will give you a pretty good idea of what's needed to run it from the Cub's pto. I think most of these have some extra shaft extending beyond the flywheel so it would be simple to connect there.

Math problem: Electric motor tag, rpms. Probably 1545. Pulley diameters on electric motor and on corn sheller. Then if any, the reduction in driving the flywheel.

Mark flywheel and drive pully on motor side. One rotation of flywheel, count revolutions on drive pully.

Do you think, if I gear down a Cub pto, that a Cub will turn it without making it a candidate for the scrap yard?

Guessing you won't need to gear the Cub down to operate the corn sheller. Considering that the electric motor is probably a 1/4 horse, you will need something to slip if there is a malfunction within the sheller.

You guys are bringing up bad memories of the turnip grinder, when I was a kid. My father didn't need to hook it up to a Cub, he had me!

[Barnyard]

There is a pulley mounted behind the flywheel that that is belted to a smaller pulley below it


The smaller pulley is on a shaft that goes through a pillow block to the other side.


The other side shows the shaft mounted in another pillow block but no pulley.


The shaft has a jagged cut and appears to have had a pulley mounted but cut off with along with part of the
shaft. The electric motor most probably ran that missing pulley and in turn powered the opposite side.

Bill,

If memory serves me correct, the "pulley" with the belt on it is a sprocket for a chain drive.

I have a McCormick-Deering sheller and that "pulley" I believe had a round leather belt that ran down to the smaller pulley. At the bottom corner there is a fan inside that blows air to clear out the chaff. I'll have to go out and look closer. Check this link for the IH sheller:

Will mine work better if I dress like the guy in the pic or would I be okay wearing just my clown suit?

Denny's link gives you a shaft speed of 225-250 RPM, that would work for yours too. You can see holes where the drive pulley bolted to the flywheel.
I have a older wood framed sheller that I belted to my Cub, it was way to fast at idle, and nearly shook it apart.
You need to run it at hit-and-miss engine speeds.
