P.T.O. not engaging

[Redman]

Our ford 6610 runs well with no load or an empty hay-baler. However, if I turn off the P.T.O. to turn around at the end of row with a partial bale in the baler, I cannot get the P.T.O. to start turning again. If I release the hay-bale, it will start turning again. On ocasion, I will be able to disconnect the baler's drive-shaft, engage the P.T.O. for a few seconds and then turn it off, reconnect the drive-shaft and reengaged the P.T.O. then the baler will run. I took it to the tractor mechanic and they changed the fluid, filter, and cleaned off the screans. When they cleaned off the screans they found a fair amount of metal shavings. The clutch for the P.T.O. was inspected and was found in good condition. They also increased the pressure to something that engages the P.T.O.
Do you have any suggestions?
P.S. if I decrease the throttle so that the R.P.M. drop below a certain point with hay in the baler, the P.T.O. will slow down and eventually stall out.

first off WHY are you turning the PTO off at the end of the row???
turning the PTO off with a partial bale is putting alot of strain on your tractor to get it started again and is creating more wear and strain on your PTO components than is necessary

new pump

He could also have a leaking relief valve or piece of trash in it reducing hydraulic pressure if you have a independent system.
Does that Ford have a live or independent PTO?
