3510 PTO not Working

[Larry_Sheehan]

MY 3510 worked fine until today. Now with the PTO selector in AUTO and the Column switch ON with the clutch disengaged the dash indicator flashes, with the clutch engaged the dash indicator is on solid as expected, but the PTO isn't rotating.

I checked the fuse, it's good. I can't find the relay or any solenoids under the tractor, and I don't see any loose wires or anything.

Any ideas?

Thanks, I already thought of that too...no joy.

I'm wondering, I think the 3510 and 4110 are the same basic tractor, in which case maybe i've got the "sticky valve" problem

Friend of mine had (yellowandbeige) a "somewhat similar" problem with his CC 7530 PTO. Check out this thread and what he found....

Look under your rt side foot rest and you will see a square block and a wire & screw attached to it. Take the screw out and clean the wire and the block to make a good ground connection. If this doesn't solve your problem on the rear edge of the block you will see the solonoid which has a wire going to it. Look on the front of the block directly in front of the solonoid there is a hex head plug. Take out the plug being careful not to lose the spring inside and stick a screw driver in the hole to push the solonoid back. Spray a little light lubricant in the hole and put the spring & plug back. I believe this should solve your PTO problem. If you have any questions feel free to call me at 585-343-0770.

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.
