946 Versatile Clutch Slipping

[Guest]

Hi, we use a 946 versatile to pull our Morris drill and have never had any problems until today. The clutch started slipping on us when we were trying to get up hills while seeding. The rpms wouldn't change but it would bog down and loose power and then start to jump and we would need to pull the drill out in order to make it up the hill. It only did this on the hills. We have a small hydraulic leak but the hydraulic fluid wasn't low and I am assuming it is the same as the newer versatiles in the sense that the tractor will prioritize the tractor hydraulic needs before that of the drill and if the pressure was to low we would see the fan stop running before having clutch issues? anyone out there run into a similar problem and know how to fix?
