Mower

Hello I have found a 22 cub sickle bar mower. I want to know if it will work on my 1941 Farmall A tractor. Thank you

The Cub PTO runs backwards so I do not think it will work for you.

I think a cubs PTO spins in the oppsite direction of any of the bigger tractors. Dont know if that would effect how it would work or not.

Might be a tad light for the bigger tractor but I would give it a try. Reason I say that is that the mower takes the rotary motion of the PTO and transitions it to the back and forth action of the knife. I am not sure that it matters which way the PTO is spinning. Having said that I'll tell you that I have never tried it...but I would try it unless there was a glaring reason in the power train of the mower indicating it cannot spin either way. Try turning the mower by hand first and see if the knife moves back and forth when the drive shaft is turned both ways.

They do go in reverse, but I can't imagine that being a problem for a sickle mower.

It's just a crank that converts it into a back and forth motion... the grass shouldn't care if it turns out to be a forth and back motion instead. : )

I'm not sure what the speed of a cub pto is vs. an A pto, so that'd be my bigger concern.

If the cub is slower, you might end up going too fast on the A, breaking pitman arms.

If the cub is faster, you might go too slow with the A, getting a lot of jams.

This all assumes you can get the mower to fit of course.

The drive pulley on a cub cycle mower has left hand threads and would unscrew itself, even if you were able to make it fit an A otherwise. Joe

As the others said the PTO does in fact turn back wards on the cub but on a sickle mower that would not be a problem unless like the other guy said the pulley was bolted on so as to hold it self on my rotation. The big problems would be lack of hyds on the A to lift the mower and also the fact it would be a tad light for it. The Cub is around 12HP and the A is around twice that so things might not hold up well

Forget it. As already pointed out, the reverse rotation won't matter to to the crank running the cutter bar. But everything else will be wrong. All frame dimensions will be too small. The A PTO only runs 1/3 the speed of the Cub. So even if you got the pulley installed on the PTO (which has a different shaft configuration), the mower would run way too slow. Because of the reverse rotation, several parts will be constantly trying to unscrew themselves. Then you would need to rig up some kind of lift mechanism as the Cub mower is designed to work with the Cub hydraulic system.

excellent point, you're right.

ya, reminds me of the old chryslers. the left side had left hand threads for the wheel studs.
