Hello all, I have a Massey 245 with the Perkins. Over the last couple years it has been really slow going up hill in the road gears and now it’s at a point where it wont even move at all in and high gears on flat ground. I just adjusted the clutch (through bottom cover) to the shop manual specs but it didn’t help any. Engine rpms are fine and clutch pedal feels good. PTO operates as it should and I can shift through all the gears. Just did all filters except hydraulic. Any ideas??
