Abstract: A power takeoff mechanism utilizes intermeshing gears as a PTO power transfer mechanism to transfer rotational power from a power takeoff input shaft to an offset power takeoff output shaft. The PTO power transfer mechanism is supported in a fluid-tight housing mounted on the rearward side of the transfer case of a four wheel drive vehicle. A braking apparatus is operably connected to the drive gear and includes a piston, a biasing spring coupled with the piston and a pressure apparatus that keeps the spring from moving the piston until the drive has been disengaged from the power takeoff input shaft. The speed of operation of the PTO output shaft can be selectively varied by changing the ratio of the respective diameters of the drive gear and driven gear within the PTO power transfer mechanism.
