520h pto

[adammurray 1]

l have a 1993 520h its running perfectly but when l engage the deck the pto engages perfectly but after approx 1 minute the pto comes to a stop over approx 5seconds as though through friction.

has anyone had this problem and know the cure ?

It is likely that the mower deck or the mule drive is causing the problem rather than the PTO. Remove the belt from the PTO and turn each of the pulleys on the deck and mule drive by hand to see where the problem may be.

Does it stall the engine when the PTO stops?     If not, you probably need to increase the pressure on the clutch plate. or replace the fiber disc if it is worn.

I wondered how the ends of the bell were wearing away on some PTOs and finally figured it out.  There are some folks that run the things with the pin broken and the hoop is actually pushing the bell.  Just something to check.  If adjustment doesn't fix it, take a photo so we can see if we can come up with a fix.
