Abstract: A manually operable control device, such as a joystick, includes a plurality of actuators for operating hydraulic valves of a machine. A handle has a sphere received within a cavity formed between a pair of seat portions which are moveable with respect to each other. The handle produces movement of at least one of the plurality of actuators when the sphere is pivoted within the cavity.

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 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: The present invention includes a single joystick for the simultaneous control of three spool valves for use on a construction machine. A first portion of the joystick is moved in a first direction which causes a cam to selectively depress a first pair of plungers to control the first spool valve. Movement of the first portion in the second direction causes the cam to selectively depress a second pair of plungers thereby controlling the movement of the second spool valve. A handle of a second portion of the joystick rotates about an axis causing a plate to rotate in a corresponding manner. The corresponding rotation of the plate causes a link member to rotate about the axis causing a pair of lugs to selectively depress a third pair of plungers to control the third spool valve. The mechanism for depressing the third plungers works independently of the position of the first portion so that the control of the third spool valve is independent of the control of the first and second spool valves.

Upon continued rotation of the knob, a drive lug on the actuator engages the upper lever to drive it the same way while the clutch disengages from the actuator and holds the lower lever fixed. Reverse motion is obtained when the clutch engages the actuator and upper lever, after which it releases the actuator and a second drive lug engages the lower lever to return it to its starting position.

Abstract: A control system including interfaced hand and foot control assemblies for independently conditioning an off-highway implement by selectively positioning a regulator thereof relative a neutral position.
