Abstract: A self-propelled lawn mower including at least one cutting blade and at least first and second rear drive wheels. Hydro pumps are provided for controlling the drive wheels. Optionally, a grass collection system may be mounted on the mower, with much of the system being located laterally rearward of the rear drive wheels so that the center of gravity of the mower is shifted rearwardly. In order to compensate for such a center of gravity shift, the respective positions of the rear drive wheels are adjustable. In certain example embodiments of this invention, the lateral position of the rear drive wheels may be selectively adjusted as desired by the operator (e.g., to move the center of gravity of the mower forward relative to the rear drive wheels in order to compensate for the added rear-heavy weight of the grass collection system).

Abstract: A power lawn mower includes at least one cutting blade driven, directly or indirectly, by an engine. A cutter deck assembly of the mower includes a cutter deck, cutting blade(s) housed therein, and a pulley/belt system powered by a drive shaft of the engine for driving the cutting blade(s). The cutter deck assembly is selectively adjustable upward/downward to adjust the cutting height of the mower and/or to allow an operator to put the cutter deck assembly in a heightened position for storage and/or transport and thereafter lower the cutter deck assembly to a cutting position. In certain example embodiments of this invention, a latch system is provided as part of a deck lift system for permitting the cutter deck assembly to be more easily and/or efficiently raised/lowered.

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.

Abstract: A lawn mower is provided. In certain example embodiments, the lawn mower includes an improved steering control system/assembly and/or an improved pump control linkage system/assembly. In certain example embodiments, the The mower includes an engine deck supporting an engine that drives the at least one blade for cutting grass, the engine deck also supporting a first hydraulic pump that controls the right rear drive wheel and a second hydraulic pump that controls the left rear drive wheel. A deck lift system is for raising/lowering the engine deck relative to both a frame of the mower and a handle control assembly.
