Abstract: A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop "wheelies" upon acceleration.

Abstract: A cruise bar is provided for use with a lawn tractor. The lawn tractor includes a frame, a driving device for use in driving the lawn tractor, a first drive wheel for use in driving the lawn tractor, a console that is operatively connected to the frame, and a first control lever for use in controlling the speed and direction of the lawn tractor. The cruise bar is used to limit the motion of the first control lever. The first control lever is operatively connected to the driving device and to the first drive wheel. The first control lever is selectively moveable in a first direction. The cruise bar limits the motion of the first control lever in the first direction and is operatively connected to the console. The cruise bar may be adjusted relative to the first control lever thereby providing a method for limiting the top speed of the lawn tractor.

Abstract: The present invention provides a hydraulic motion control or pilot valve and lever assembly for controlling the transmission and steering of a work vehicle such as a crawler tractor, articulated wheel loader or like construction vehicle. The motion control valve and lever assembly is a compact assembly that employs a single lever mounted directly to a valve in order to control the forward and reverse motion of the vehicle, the steering of the vehicle in a left, right or straight direction, and the speed or gear selection of the vehicle. The valve assembly is provided with eight hydraulic signal ports, at least one reservoir port, and at least one pressure supply port. The assembly further has four control spools positioned in respective control spool chambers spaced approximately ninety degrees apart and a fifth control spool positioned in a fifth, central spool chamber. A two-way pivot interconnects the fifth control spool and the control lever so that the control lever may pivot about two axes with respect to the fifth control spool. A cam assembly mounted to the control lever comprises a cam positioned adjacent first ends of the four control spools, a cam bracket mounted to the cam, and a bearing disposed between the cam bracket and the control lever so that the control lever may rotate axially with respect to the cam assembly. When the control lever rotates axially, it in turn causes a corresponding axial rotation of the fifth, central control spool.

Abstract: A steering and ground speed control mechanism of a vehicle equipped with a dual-path hydrostatic drive system includes a pivot plate fixed to a vertical pivot post at a location between and equidistant from a pair of locations respectively linked to a pair of pump displacement control arms of a pair of pumps respectively coupled for delivering fluid to right- and left-hand drive motors coupled to right- and left-hand ground wheels. A train of elements for transferring steering inputs from a steering wheel to the pivot plate includes a timed belt and sprocket set with one of the sprockets being fixed to the pivot post and the other mounted to a fixed post together with a quadrant-shaped steering rack for pivotal movement about the fixed post in concert with the rack. Pivoting the pivot plate in opposite directions from a centered position causes different displacements of the pumps and, hence, in the two drive motors being driven at different speeds. A train of elements for transferring speed inputs from a speed control lever to shift the pivot plate back and forth in a nearly straight path includes a push-pull cable coupled between the lever and an arm having the pivot post pivotally mounted in one end thereof, with the arm being mounted for pivoting about the fixed post exclusive of the rack and sprocket. A spring-applied, hydraulically released latch is provided for latching the steering wheel and speed control lever in their respective "centered" and "neutral" positions when hydraulic pressure is absent and a "neutral" start switch is positioned for being activated for completing a vehicle starting circuit only when the steering wheel and speed control lever are in these positions.
