3510 PTO not Working

Thanks, Galen.

I can now verify that it was the "Sticky Valve" problem. I called Bill's tractor in Liberty Hill, TX (my dealer) and he verified that that would be the first thing he'd try.

Copied this from another thread on 4110s:
The problem most of the time is not the solenoid itself but the spool valve it works when voltage is applied. The end of the spool is completly open on the end so grit can get inside causing the valve not to open. If your pto does not operate you can get underneath the tractor with it not running of course and simply push in the valve with a small nail or ball point pen. The valve is easy to locate if you look under the right side floor panel you will see a valve block with hydralic lines connected to it , to the rear you will see the solenoid which has two wires attached to it ther will be a plastic nut holding it in place in the center of this nut you can see a steel valve end approx. 3/16 of an inch in diameter. simply push in on this valve a few times and the pto should start working when you get back on the tractor. It seems to help if you spray a little wd-40 on the exposed area. This problem seems to happen on tractors that are not used for extended periods of time.



I hit the valve under the right floorboard with some WD-40 and operated it by pushing it in with a nailset a couple times. Worked great all afternoon.
