Hi,
The first place I would look would be the frame ground for the engine and clutch. Then checking for power to the clutch that is continuous. PTO switches often become intermittent internally. The blue wires to the switch should have the power on them.

I agree with Crigby ,
But on some of the older units ,the clutches you had to set the air gap between the plates
