ABSTRACT:
A mower has a frame that supports a rotary cutting deck. The frame includes a pair of side rails that each extend from a front end in advance of the cutting deck to a rear end substantially behind the cutting deck. The front ends of the side rails support a pair of front caster wheels. The rear ends of the side rails have a raised, upwardly extending arch at which a hydraulic pump/motor assembly is mounted. The pump/motor assembly has an L-shaped configuration with the motor being located towards the bottom of the arch and outboard of the side rail and with the pump extending upwardly and inwardly from the motor to be located inboard of the side rail and within the vertical profile of the arch. The hydraulic motors drive a pair of rear drive wheels to propel the frame over the ground. A cross frame extends between the motors in the pump/motor assemblies to join the assemblies together. The deck is propelled from the frame by a plurality of struts extending between the cross frame and the deck.
