ym146 pto shaft

[hickboyy]

I recently got a ym146 that came with a tiller, but I do not have the tractor end of the shaft. The previous owner modified it to fit on a mt372, which has a male 6-spline PTO. Anyone know where to find a 15-spline yoke or conversion shaft that will fit the ym146 female PTO?

Try Agri Supply Co.'s online catalog...they have a couple of pages of adapters...if you don't see what you need, call them and ask for their PTO person...they'll fix you up and have very reasonable prices and fast shipping.

Are you sure there is not some oddball adapter on the end of your pto shaft? The Ym135 and YM147, similar tractors, have a 6 spline male pto shaft like every other Yanmar that I have seen.

Nope, I'm sure it is a female hook-up on the back. Here is a video that has been kicking around some time, it shows a good close-up of the PTO.

Oh, I see. The 146 is a garden tractor, the others are all just small regular ag tractors.

Yeah, but it originally was able to run a 4' tiller, I would like to be able to make it be able to do it again.

The problem with your conversion is that your rear PTO turns 2000 RPM; the tiller is designed to turn at 540 RPM. You will be turning it approx. 4 times faster than it is designed for.
You need a tiller designed for a 'garden tractor'. Most name brand companies offer tillers for their 'garden tractors'. Go talk to a John Deere or Cub Cadet dealer.

I looked closer at my tiller, it is reduced 9:1. The math works out to about 220 RPM on the tines @ 2000 RPM PTO speed. This all adds up to the tiller being right for my machine, but I still need to figger out how to drive the darn thing.

How many Yanmar Authorized Parts Dealers have you contacted? I suspect that will be your only source. Is the tiller also a Yanmar? If so, there should be parts manuals with #'s.

Not sure these folks could help you but it might be worth a phone call. Bolens parts
