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 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.
