Abstract
A self-propelled power equipment unit having a frame with a handle having a general U-shaped rear end; a drive located on the frame and connected to a drive wheel by a transmission; and a user actuated control connected to the transmission. The user actuated control comprises a speed control lever pivotably connected to the handle proximate the U-shaped rear end and an operator presence lever pivotably connected to the speed control lever.
Claims26
A self-propelled power equipment unit comprising:
- a frame comprising a handle with a general U-shaped rear end;
- a drive located on the frame and connected to a drive wheel by a transmission;
