1976 MF 245 diesel with draft control disabled.
After about 45 minutes of pulling a bush hog, the PTO slowly lowers the deck until it is scraping the ground.
At this point, the PTO will not raise the deck.
The only temporary solution is to turn the tractor off for a few minutes. Sometimes the PTO would raise the deck on startup. Other times, on the drive back to returning the tractor to storage, the PTO will suddenly raise the deck.
How do you troubleshoot this ?
