Abstract: A traction and steering control system and method for a small- or zero-radius-turning maintenance vehicle. The traction and steering control system may determine operator intended speed and direction by monitoring positions of speed and directional control members and one or more operational parameters of the vehicle. The vehicle may then generate drive wheel speed commands that achieve the intended speed and direction by determining how best to manipulate the left and right drive wheels. In some instances, the drive wheel speed commands are disproportionately related to the positions of the speed and directional control members.

Abstract: A walk power mower has a traction drive system that includes a front transmission powering a pair of front wheels and a rear transmission powering a pair of rear wheels. A first one of the transmissions provides forward motion of the mower when it is active and a second one of the transmissions provides rearward motion of the mower when it is active. A slidable handle grip on the handle having a cross bar long enough to be gripped by both hands of the user activates the first one of the transmission when it is slid downwardly on a handle out of a neutral position thereof. The slidable handle grip activates the second one of the transmissions when it is slid upwardly on the handle out of the neutral position.
