PTO Problem Cub 2164 Vanguard

[FLBill]

My tractor's PTO will only engage for a short period of time. After I pull the dash PTO switch the PTO engages. Soon after I depress the forward accelerator the PTO stops working. The time the PTO works varies, but it is never very long. I disabled the reverse and seat PTO cutoff switches. That did not resolve the problem. The tractor only has about 75 hours on it.

What is wrong with my tractor?

Thank you for your help. I and my lawn appreciate it.

Might be loose wire in the connector to electric pto , I have White here that blades shut down on with a bump 3 years latter found the loose wire.

Pull back the protective sleeve over the PTO harness to check for breaks. Something is dumping the juice to the PTO, it's a matter of tracking it down. At first I would have guessed the seat switch was getting tripped, but if you jumpered it out, that takes that out of the picture.
