A power take off assembly for a work vehicle includes an output drive member drivable at various speeds and power levels and an output shaft for coupling to the output drive member. A hollow cylindrical break-away drive collar include a first end having a first set of splines for meshing with corresponding splines of the output shaft, a second end having a second set of splines for meshing with corresponding splines of the output drive member and a central neck portion located between the first and second ends. The neck portion is constructed so that, as a result of accumulated torque damage, the drive collar will break apart at its neck portion to prevent transfer of torque to the output shaft and so that the drive collar will break apart before the output shaft breaks. A bearing assembly rotatably supports the output shaft and is fixed with respect to the vehicle.
