ABSTRACT:
An operator control system for a self-propelled vehicle such as a lawn mower is provided wherein the control system includes two opposing and preferably upwardly extending and converging hand grips each having a corresponding drive control lever associated therewith. Each drive control lever may have at least a portion that is parallel to a grip axis of its respective hand grip. Further, each drive control lever may have a pivot axis that is substantially parallel to the corresponding grip axis such that the drive control lever remains substantially parallel to its respective hand grip throughout its travel. In some embodiments, a neutral lock is provided to permit locking of each drive control lever in at least one position, e.g., a neutral position. Secondary levers such as operator presence control (OPC) levers may also be included. In one embodiment, an OPC lever is associated with each hand grip.
