Abstract
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.
