PTO won't engage

PTO won\'t engage

After owning my 4210 for three years I finally needed to use the PTO for the newly aquired backhoe. I pulled the PTO knob up as per instructions, the PTO light on the dash lit but the PTO didn't engage /forums/images/graemlins/confused.gif.
I drove 70 miles roundtrip to the JD dealer, spoke to the Service Mgr who said it could be a solenoid, wires loose under the transmission or the transmission itself. At that point, I went to the parts counter to buy a repair manual....$180 with 7-10 days for delivery. Nothing's easy...

Can anyone help with a diagram of the wiring and/or the internal part in the transmission that may/or may not be broken????

Re: PTO won\'t engage

Do you have a front PTO as well? Could you have the lever set to actuate the front PTO? I'm often putting the selection lever in the front position so the rear PTO shaft will free wheel to allow me to put the PTO shaft onto the rear a bit easier and then forget when I pull up the PTO engagement button. I immediately know where to look now.

You could have ordered the repair manual on CD by phone.

Re: PTO won\'t engage

By far the most likely suspect is the pto solenoid. It is on the transmissions right side, about 10 inches behind the travel pedals (assuming hydro...)

The wires can get snagged and pulled off the solenoid.

If you need a diagram or two, pm me with your email address...

Re: PTO won\'t engage

Ralph, I do not have a front PTO. Do you have the phone number to order the CD manual?

Rocky I looked underneath and didn't see any loose, disconnected or broken wires. I even checked the mini fuses which are good.

Underneath the floor board, there's a metal rectangular box that's 2"wide x 5"long x 1-1/4"thick. It has two hard lines (hydraulic?) on each end and has what appears to be a wired solenoid attached on top. Would that be the solenoid that engages the PTO? How do I remove that solenoid to check if it's good or not? Is it screwed in or does it "lift" off?
If it is good, what's the next thing to check for??

Thanks to both for your replies.

Re: PTO won\'t engage

Is there a PTO selector on that model?

Re: PTO won\'t engage

No PTO selector. Just a pull/push knob on the right side beside the 3pt up/lower slide control.

I just removed the backhoe from the tractor. I grabbed the PTO shaft to turn it, but it only turns a little bit then "clink" like there's a stop internally, preventing it from turning anymore. It also "clink" going the opposite direction.

BTW here's a pic of the backhoe on the JD.

Re: PTO won\'t engage

Thanks for the number. I'll call tomorrow and order one.

BTW is the repair manual in a CD version better than one in hard copy? Is it "user friendly"? Just curious... Thanks

Re: PTO won\'t engage

I just worked on my JD 4410 and had a bad solenoid on the dirverter. Its called a control valve. The front one goes to the 2 wheel drive switch. The rear one goes to the PTO. My PTO one had 11.1 ohms resistance and was good. My 2 wheel drive one was 0 ohms, and had gone to ground blowing a fuse. I paid $33 for the control valve and took about 30 mins to replace it. You can just unplug the wires and check resistance without taking it off. Hope this helps. /forums/images/graemlins/wink.gif

Re: PTO won\'t engage

Where's the solenoid located? I don't have a manual to use as a reference.
Thanks
