ABSTRACT:
A single lever blade control apparatus for bulldozers that is capable of operating in three mutually perpendicular planes to activate three independent hydraulic valves controlling a bulldozer blade: up/down, tilt and angle. Movement of the bulldozer blade in an up/down motion is accomplished by the operator by pushing the single lever apparatus in the X direction, the X direction corresponding to the longitudinal axis of the bulldozer. Movement of the bulldozer blade in the tilt direction is accomplished by the operator pushing the single lever apparatus in the Y direction. Angling the bulldozer blade is accomplished by the operator rotating the handle of the single lever apparatus about the Z axis. The invention works with all variations of hydraulic valve placement.
