A spring loaded snubber brake is provided for a Power Take Off (PTO) shaft of a tractor. The brake is carried by the PTO shaft and utilizes the centrifugal force created by the spinning shaft to become disengaged as the shaft rotates and become engaged as the shaft is declutched. Since the brake does not apply any frictional force on the shaft as it rotates, there is no parasitic loss of PTO output horsepower. As the shaft is declutched and comes to rest, the brake springs urge it into engagement with the shaft to prevent inadvertent rotation of the shaft due to residual forces produced by hydraulic fluid forces operating on the PTO drive components.
