Abstract: A mower which may include: an engine for driving at least first and second cutting blades, wherein the first and second cutting blades are located in first and second cutting chambers of the cutter deck structure, wherein the cutter deck structure may include an inclined surface in the first cutting chamber so that at least part of the inclined surface is located closer to the trim side of the cutter deck structure than is any cutting blade rotational axis, the inclined surface extending downwardly from an upper surface of the cutter deck structure toward at least the trim side of the cutter deck structure, wherein the inclined surface slopes downwardly from the upper surface in a direction away from the side-discharge opening; wherein the inclined surface is configured to help provide a high pressure zone within a rear portion of the cutter deck structure and a low pressure zone proximate the trim side of the cutter deck structure for helping vegetation to be cut to be pulled into the first cutting chamber.

Abstract: A lawn mower includes a deck structure having, in an embodiment, a baffle with teeth at a front end of the deck structure opposite to a discharge opening for directing vegetation to be cut into the pathway of a blade. A trim divider edge portion, in an embodiment, prevents long vegetation from sliding around the edge of the deck structure. A trim vacuum structure portion, in some embodiments, in the form of an inclined surface at the rear end of the deck structure opposite a side of the discharge opening or at a center location of the deck structure reduces pressure within the deck structure for lifting vegetation to be cut.

The mower includes a deck lift system for raising and lowering the cutter deck assembly, an engine deck and the engine together as a unit. The deck lift system including at least a deck lift lever for selective operation by an operator of the mower and first and second biasing springs for at least helping raise the cutter deck assembly, engine deck, and engine. Biasing springs collectively provide sufficient biasing force so that operator of the mower has to physically push down on the deck lift lever in order to lower the cutter deck.

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).

In certain example embodiments, the lawn mower includes one or more of: (a) a cooling baffle for efficiently cooling a hydraulic fluid tank and/or fluid therein using air flow caused by a combustion engine used for driving mower cutting blade(s); (b) improved cockpit structure including fenders; (c) improved drive wheel(s) adjustment structure or assembly; (d) improved idler arm assembly for use in connection with the cutter deck and/or pump driving belt; and/or (e) improved hose routing structure.

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: This invention relates to a lawn mower. In certain example embodiments, the lawn mower may be of the walk-behind type. In certain example embodiments of this invention, the lawn mower may have one or more of: (a) an improved handlebar weldment assembly, (b) an improved operator presence control (OPC) system and structure, (c) an improved speed control system structure, (d) an improve cam bar system for hydraulic pump control, (e) a return-to-neutral biasing system that biases hand lever(s) toward a neutral position but only from a reverse position (not from a forward position), and/or (f) an improved tracking adjustment system.

Abstract: A walk-behind lawn mower includes at least one of: (a) a latch assembly for receiving a folded-up sulky for storage during transport and the like; (b) inboard mounted control rods extending downwardly from a handle control assembly area of the mower, so that actuator shafts for the hydraulic pumps are located on inboard sides of the pumps so as to oppose one another; (c) a handle control assembly for allowing the mower to be operated in an efficient manner with operator comfort during turns and the like; and/or (d) a pump lock-out system including a lever(s) for actuating both a braking force to be applied to at least one wheel of the mower and a pump lock-out system for causing the pumps to be locked in a neutral position.

Abstract: A lawn mower that includes, a deck lift system, is disclosed. The deck lift system may lift/lower the cutter deck, engine deck, engine, and handle control assembly together at the same time.

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.
