GC 1705, is there an easy fix or adjustment? Pto starts slipping when machine is hot, hydraulic oil is at the proper level, engine rpms do not drop, just the pto slows/stops turning. Either with rear PTO or mid mount
I believe the GC series have a hydraulic operated PTO clutch so first thing I would do is find out how to check the PTO hydraulic pressure since the pressure may drop as oil heats up due to thinner oil will leak more through the same size leak path.
The service manual should describe this procedure on where and how to check this pressure.
@kennyd of Ken's Bolt on Hooks fame, I believe sells a pressure gauge with the hose and fittings to fit ... That's where I got mine ... It plugs into a loader line ...
Book calls for 1920 psi IIRC ... For my GC 1725 MB.
If you don't have a loader, either Kenny or @dicktill may have a suggestion where to plug into the system ...
