Farmall 460 PTO question

Erik MN · Sep 21, 2009

Hi all,

I posted about a week ago regarding a Farmall 460 that has been sitting for about 7 years. I followed your advice and used ATF in the cylinders and changed the fluids and took the carb apart and cleaned it out and it started right up!! Even the TA works great.

One issue I did notice however, the PTO lever will not turn off the PTO. It stays running whether or not the lever is engaged or disengaged. Any ideas? I am new to the Farmall family, and very much appreciate all of your expertise!

Congratulations on your accomplishment! Sounds like it will be a fine tractor for you. We had a 560 when I was growing up. I think the PTO lever design is similar. It needs to be locked down in the OFF position or the PTO may continue to rotate. I am guessing you just need to lubricate and loosen all the linkage to make sure everything is freed up properly.

Does it do this with a load on it? Or just when it's not hooked to an implement? May just be linkage like has been mentioned or a slight clutch adjustment. Dad's 460 pto turned some at times, but hooked to his haybine or whatever, it didn't. Only drawback was hooking it up... needed to shut the engine off to be sure it wouldn't turn on you.

Thanks for your insight - it is much appreciated! I will look at the linkages for the PTO and make sure the lever is locked in this weekend when I see it again. I am really excited about getting it running and ready to go!

Those independent Pt's came with an adjusting wrench. That is what the big hex nut is for on top of the unit. The wrench was made so you could press down on the holding spring inside and rotate the PTO to increase or decrease the cluth plates. "Those wrenchs are hard to find." Sometimes they will turn while cold and stop when the oil inside warms up. Might try changing the PTO oil. It has a drain plug below and doesn't hold a lot of hy-tran. No real big deal or it could be if it will not stop at all. Adjustment to the linkage as discussed might help. BE CAREFUL though. A never stop PTO is not safe.
