Good Morning All-
I am new to the site, so I apologize if this is a repost, however I am looking for some insight into an issue with my '97 JD 425. The tractor starts fine and runs well. PTO ( with 60" deck) will engage and operate for about 5-10 minutes, however after that the entire tractor stalls (PTO and Engine). if I can catch it quick enough and disengage the PTO in time, the engine wont stall out. If the engine does stall, I have to choke the tractor a bit ( even if it is warm) and it will start back up. I took the deck off the machine and drove it around with the PTO engaged and no implement. it seemed to operate fine like this. I have gone through the deck, everything seems to be spinning freely and nothing appears to be bent or miss-aligned.
Kawasaki 20HP engine, serviced regularly
Things I have already tried
time delay module
serviced/ cleaned deck/ changed out blades
Could this have to do with PTO solenoid/ Module/ Switch?? could it be the seat switch??
any help would be appreciated
