Abstract
A PTO clutch includes a lubrication shut-off valve that can slide between a first position blocking a port for lubrication oil to lubricate the PTO clutch, and a second position opening the port to lubricate the clutch. A relief valve is provided in the lubrication shut off valve, which opens in response to pressure spikes of activation oil and isolates the pressure spikes from the clutch piston.
