Abstract
A self-propelled lawn mower includes at least one cutting blade, at least first and second drive wheels, and hydro pumps for controlling the drive wheels. At least first and second belts are used to drive the pumps and blade(s) of the cutter deck, respectively. In certain example embodiments of this invention, the belt(s) for driving the hydro pumps is/are provided at an elevation lower than a belt(s) for driving the blade(s) of the cutter deck. In certain example embodiments of this invention, this advantageously permits the center of gravity of the mower to be lowered by permitting the hydro pumps and/or engine of the mower to be positioned at a lower elevation. In certain example embodiments, one or both of the hydro pumps is/are mounted on a pump deck which is at an elevation lower than that of the engine deck where the engine is mounted.
