摘要： A zero-turning radius self-propelled power lawn mower includes a standing platform structure for supporting a standing operator during mower operation. The mower has a combination parking brake and pump lockout structure which, when actuated, simultaneously applies a braking force to rear drive wheels and prevents hydro pumps from being moved from their neutral positions. The mower also includes a biasing system for automatically returning hand control levers to their neutral positions when they are not being manipulated by an operator. Unique cutter deck structure, caster structure, grass catcher structure, and steering control levers are also provided.

摘要： A self-propelled power lawn mower is provided with an improved deck lifting system. The operator can efficiently lift the cutter deck (and optionally the engine deck as well) in an efficient manner by pulling upward/backward on a deck-lifting lever. Moreover, a latch system is provided for enabling the deck to be lowered and/or adjusted in an efficient manner.

摘要： A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop nullwheeliesnull upon acceleration.

摘要： A self-propelled power lawn mower for operation by an operator. The operator can operate the mower while standing on a foot platform, or alternatively when sitting down on a selectively deployable seat. Thus, the mower includes both sitting and standing modes. In certain embodiments, at least a portion of the foot platform is located between first and second rear drive wheels. The rear drive wheels are independently driveable in both forward and reverse directions at variable speeds so as to allow for approximate zero radius turning of the mower about a vertical turning axis. The foot platform is positioned near this vertical axis so that the operator when standing may be substantially unaffected by centrifugal force created during approximate zero radius turning of the mower.

摘要： A grass catcher is provided for attachment to a lawn mower such as a commercial lawn mower. In certain example embodiments, the catcher includes at least one baffle for causing a venturi effect during grass cutting operation. The presence of such a baffle may allow for reduced grass clogging and/or improved grass packing in the catcher during mower operation in certain example instances.

摘要： A zero-turning-radius power lawn mower for operation by a standing-occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing-occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero-radius-turning of the mower about a central turning point. The riding platform is positioned at this turning point so that the standing-occupant remains substantially unaffected by centrifugal force created during approximate zero-radius-turning of the mower thereby allowing the mower to take such turns at higher speeds. Such positioning of the platform also provides for improved maneuverability, reduces the likelihood that the platform will bottom out when the mower goes over bumps, and creates a safer mower less susceptible to tipping due to the resulting low center of gravity. The low center of gravity created by the position of the riding platform for the standing-operator also results in the mower having improved traction and being less likely to pop nullwheeliesnull upon acceleration.
