In a riding lawn tractor having a parallelogram front wheel suspension, a rigid support member on the tractor frame is of inverted U-shaped cross-section, with downwardly projecting front and rear walls, and the wheel brackets are pivoted to its opposite ends. A tubular bushing has one end portion received in a closely fitting hole in one of those walls; a flange secured to the bushing near its other end flatwise overlies the other wall and is bolted to it. A power takeoff shaft is rotatably housed in the bushing and has end portions that project forwardly and rearwardly beyond it for connection to a front-mounted implement and an underslung mower, one of those end portions also supporting a pulley for a belt connection between the shaft and the tractor engine. The bushing also serves as a trunnion for a tiltable mower hitch support.
