摘要： A deck lift system raises and lowers the cutter deck assembly together with the engine deck and engine as a single unit in order to adjust the cutting height of the mower. A tractor frame supports a foot platform and/or a seat upon which the operator may sit. The tractor frame includes first and second spaced apart sidewalls that are connected together with at least a cross wall member. A depression is formed at the rear of a cutter deck in order to enable a clutch of the engine to be moves closer to the grounds and/or further forward than would otherwise have been possible absent the depression.

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 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 “wheelies” upon acceleration.
摘要翻译：用于由站立乘员操作的零转弯半径功率割草机包括安装在单独驱动轴上的第一和第二独立驱动和受控的后驱动轮。用于支撑站立乘客或操作者的骑乘平台位于第一和第二后驱动轮之间。后驱动轮可以以可变速度在前后方向上独立地驱动，从而允许割草机围绕中心转折点基本上为零半径的转动。骑乘平台位于该转折点或轴线附近，使得站立乘员基本上不受由割草机近似零半径转动期间产生的离心力的影响，从而允许割草机以更高速度进行这种转弯。由立式操作者的骑乘平台的位置产生的低重心也导致割草机具有改进的牵引力，并且在加速时不太可能弹出“轮椅”。

摘要： A self-propelled power lawn wherein an operator can operate the mower while standing on a foot platform, or alternatively when sitting down on a selectively deployable seat. The operator may operate the mower from a standing position regardless of whether the seat is deployed or not. A shorter control arms extending between a tractor frame structure and a cutter deck assembly having a mower deck lift system raising and lowering the cutter deck assembly together with the engine deck assembly. A portion at the rear of the cutter deck assembly cut out and covered with a plate in order to form a depression over a rear edge of the cutter deck. This depression enables the clutch located over top of the depression (and thus the engine) to be located at a lower elevation so as to lower the overall center of gravity of the mower.
