摘要： Disclosed is a self propelled walk behind mower comprised of a tractor unit and a mowing deck. The tractor unit is hydrostatically driven with a unique control system whereby the forward speed of the tractor is set by operating an electric rocker switch with an operator's thumb. Hand levers are used to turn the tractor to the left and the right. The tractor unit comprises two drive wheels and a third wheel that is pivotally attached, letting the tractor unit stand upright when no implements are attached. Implements attach to the front of the tractor through a movable attachment so that the tractor and implement can closely follow the contour of the ground while keeping the operator controls in a convenient position.

摘要： A utility vehicle with foot-controlled mobility is provided that includes a skeletal frame structure supporting a gasoline engine which utilizes a belt drive system to drive hydraulic motors with one hydraulic motor disposed at each rear wheel. The vehicle includes four wheel and tire assemblies, substantially at each corner with the rear wheels being driven and the front wheels being formed as casters for 360null rotation to provide a zero turning radius vehicle. The user sits upright in a manner wherein the user's legs are supported on pivotal leg support plates to allow the user to sit upright with legs directed down and away from the waist to allow the user to operate a hand-held implement. Both speed control and directional control are provided using pivotally mounted pedals with one pedal controlling each hydraulic motor. Movement of the pedals allows individual motor control to provide drive steering and speed control.

摘要： An omni direction vehicle with a frame having a round surface about its perimeter with no apparatus mounted on the frame extending beyond the perimeter. Two independent drive wheels located on an axis through the center of the frame are mounted at the same distance from a central vertical axis through the frame. Each wheel is powered independently of the other and can rotate at variable speeds in either direction. The vehicle is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The vehicle can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground. Thus, the vehicle requires a zero turning radius and requires only the space it occupies to change its forward orientation.
