755 PTO problem

[Derwin]

My PTO will not engage when placing the lever to the ON position. Nothing seems to be wrong mechanically. The 10 AMP PTO fuse under the hood is not blown. When engaging the lever I get no voltage at the fuse so I'm concluding the circuit is not made. Does anyone have a electrical schematic they can upload or a PTO troubleshooting section from the shop manual? Any help is greatly appreciated.

Is the magnet working on the pto engage lever?

PTO troubleshooting pages and schematic from the 755 manual. Some have had a mechanical adjustment problem where the lever does not move quite far enough forward to engage the magnet.

gsdavis1, I removed the side panel today to investigate this problem further. In response to your question the magnet IS NOT energizing and moving with the PTO lever. Next is to find the root-cause.
JD755, Thanks for posting the related documentation.

Sounds like your headed in the right direction. Keep us posted I have had issues with that magnet too !

Hi, this is my first post here and I'd like to resurrect this thread since I'm having the exact same issue.

I did the magnet test with a screwdriver and it seems the magnet is failing but I'm not sure how valid that test case is since there isn't any current getting to the magnet. That was tested with ignition on but engine not started, pto lever up, seat switch pulled out in by-pass mode. I've checked the seat switch, fuses etc. All the easy stuff. Now I'm pulling my hair our trying to fix this with a major job using the PTO one week away.

Am I testing this properly?

Included a pic of the harness I'm talking about.

Any and all help is appreciated.
thanks,
Rick

This is the JD way of testing...

You don't mention the position of the pto selector. When the seat switch is pulled up, the pto will not work if lever is set for mid pto or both pto, only rear works with seat switch pulled up.

Yes, seat switch taped down, rear PTO.

Thank you for this. I did 13 and got voltage. Now to expedite getting a magnet before next weekend.

Two more questions. Does anyone know what part no. this is?...and who I might contact to get one in a short amount of time?

Thank you @rara avis! Very helpful.

Is there any chance I could get you to post step 12 as well?
