Dlx pto keeps kicking out

Recommended Posts


After about 15 minutes of mowing with my 20HP DLX the pto kicks out. So I pull it to the garage and adjust the clutch again and the pto engages again. Hmmm whats the deal here

Also check the ground wire; make sure it's making good contact. Without a good ground, it'll act the same way as not enough voltage.

If you have a small voltmeter, wire it directly to the PTO +12v feed and monitor the voltage when mowing. If the voltage slowly drops you might have a partially broken/pinched wire that increases in resistance as it heats up under load. Should be a constant 12v at the PTO terminal at all times.

A weak relay in the clutch electrical system will cause that problem. I'm not sure if your tractor uses relays, but it is a possibility.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
