    Abstract: An earthmoving system (100), includes in one embodiment a laser transmitter (102) for transmitting a reference beam of laser light (104), and a laser receiver (126) mounted on a mast (128) on the bulldozer blade (110). The bulldozer (106) has a frame (108) and a cutting blade (110) supported by a blade support (112) extending from said frame (108). The blade support (112) includes hydraulic cylinders (114) for raising and lowering the blade (110) in relation to said frame (108), and for tilting the blade along its length. The mast (128) extends upward from, and is movable with, the blade (110). An inclinometer (134) is mounted for movement with the blade to provide an indication of the inclination of the blade (110). A sensor (160) detects turning of the bulldozer (106). A control (140) is responsive to the laser receiver (126), to the inclinometer (134), and to the sensor (160), for controlling the operation of said cylinders (114) and adjusting the position of said blade (110). When rapid turning of said bulldozer (106) is detected the control (140) operates to reduce the errors that would otherwise result from an erroneous inclinometer (134) output.

    Abstract: A hitch assembly (1) commonly used between an accessory (such as a front end bucket) and a tractor or prime mover (such as a skid steer loader). The hitch assembly (1) includes a bearing arrangement, partly integral with one of two frame members (2, 3), which allows the two frame members (2,3) to rotate relative to one another. The two frame members (2, 3) are attached to the tractor via adaptor (61) and the rear of the accessory (eg bucket 60). The bearing portion thus enables rotation of the accessory (60) about an axis substantially parallel to the longitudinal axis of the tractor. Automatic control in conjunction with laser type levelling systems or GPS contouring of sloped surfaces is also possible.

    Abstract: A method and apparatus for accurately positioning a tool on a mobile machine are provided. The machine operates within a work area about which one or more stationary laser-based subsystems are positioned. The machine includes an on-board subsystem, which comprises a processor, a satellite positioning system (SPS) receiver, a stored digital terrain model (DTM), and a photosensor for detecting a laser beam. The laser beam provides a reference level that is used to adjust the position of the tool. The on-board subsystem determines the current position of the machine using the SPS receiver and accesses the DTM to determine a design elevation corresponding to the current location of the machine. Based on the design elevation, the on-board subsystem computes a height command and transmits the height command to at least one of the laser-based subsystems. Each stationary subsystem includes a vertically telescoping mast on which a laser is mounted, a servo mechanism for raising or lowering the mast, and a receiver for receiving a height command from the on-board subsystem in the machine. The stationary subsystem raises or lowers the mast to adjust the elevation of the laser beam according to the height command.

    Abstract: A method and apparatus for controlling a work implement (14) movably connected to a work machine (10). An implement controller (28) automatically controls simultaneous first and second control modes of operation assigned to the work implement (14). A sensor (42) applies a signal to the implement controller (28) indicating position of the work implement (14). The implement controller (28) reverses the simultaneous first and second control modes assigned to the work implement (14) upon detecting a predetermined movement of the work movement. The implement controller (28) also automatically moves the work implement (14) from a first rotation position to a second, mirror image rotational position upon operator actuation of a manually actuatable device (49). The simultaneous first and second control mode assignments may also be changed by actuation of the manually actuatable device (49).
