ABSTRACT:
The present invention relates to powered vehicles (e.g., lawn mowers) and, more particularly, to a velocity control system for use with such a vehicle. In one embodiment, the vehicle includes a power source such as an internal combustion engine and one or more drive control levers incrementally movable between a neutral position and a maximum velocity position. The system may also include a velocity adjustment member and associated mechanism that permits changing of a ratio between control lever movement and velocity of associated drive members or wheels. Thus, the system may limit a maximum ground velocity of the vehicle while the drive control lever(s) are positioned in the maximum velocity position and while an output level of the power source is maintained at a constant level.
