DX29 PTO light stays on, tractor will not start

ms1780 · Aug 27, 2017

Hello all,

I purchased a DX29 today knowing that it had an issue where it will not start with the key. You can jump the solenoid and it starts fine. The first think I noticed is the PTO light on the dash stays on all the time.

I have read other forums and have checked the fuses. I also checked the pink wire on the solenoid to see if it is getting some voltage, but low voltage to indicate a ground problem and it is getting no voltage when the key is turned.

This tractor has mid and rear pto. The mid pto lever has an obvious pressure switch that the linkage presses when engaged. With the key on I can press this switch and hear a relay click so I believe this switch is working as it should. The rear pto does not have a pressure switch that I can find. There are two switches of some kind that thread into the rear end close to where the pto engagement linkage enters that I assume would be related to the pto switch. They have two black wires each coming off of them. Is there a way to jump these switches and see if the pto light goes out and if the tractor will start? Does anyone know which one of these two switches are for the pto and what the other one is for?

Thanks in advance!

Mike

I don't want to send you on a wild goose chase, but check you fuel solenoid. On my father's 4100 John Deere he has blown the fuel solenoid twice. It is real sensitive. A little short and poof it is toast. The tractor just clicks. The click is the fuel solenoid and it gets hot to the touch. I would try to figure out where exactly the click is coming from. If it is the fuel solenoid, it is a booger to change. On a John Deere you'll think they grabbed a fuel solenoid and built the tractor around it.

Sounds like the PTO switch is stuck. Hopefully an easy fix. The dx29 is the same as the NH TC 29 right? If so, send me a PM. I have a service manual with your name on it.

I was able to find out the lower and further back switch is the PTO switch. When the PTO is engaged the switch is closed and when the PTO is off the switch is open. That switch seems to be working.

I sent you a message. Thanks.

I was able to find the problem. I pulled the cover off the right side below the dash and found a wire that had fallen out of the bottom of a relay plug. I took the opportunity to clean the debris and mud dobber nests out too. Thanks for the help.
