I started the second day this year brush hogging. After about 4 hours the PTO quit. It has the independent hydraulic clutch for the PTO.
I stopped, checked the PTO lever had not disengaged (it had not). I decided to drive back to the barn. I was in a valley up hill the only way out. Half way up the hill the HI-Lo acted like it was slipping. In the past if it slipped on hill, it was from low fluid level. I backed down the hill to a level spot to check the fluid level. Backing down power steering quit. Then I tried the 3pt and it would not respond.
I checked the fluid level. It was OK. Removed the fill cap and the fluid smells burnt. Bad news .
The coolant gauge on the tractor never went past straight up, normal operating temp. I let it set an hour to see if the hydraulic fluid would cool and hydraulic return. They did not.
I know the transmission pump feeds the PTO clutch and Hi-Lo, then the main pump, which feeds PS and 3pt.
I am guessing the trans pump failed or an internal line broke. Or maybe the filer bypass failed/stuck in bypass?
I still have to get it towed to the barn before I can do anything.
