  • Publication number: 20140034339
    Abstract: A load sensing pin disposed to receive a load applied in a direction substantially transverse to a longitudinal axis of the pin. A load sensor is substantially fixedly oriented with respect to the applied load or alternatively with respect to the pin which is rotationally restrained with respect to a support structure. The load sensor is disposed to generate a load signal corresponding to strain of the pin resulting from the applied load.

  • Patent number: 8408149
    Abstract: A ground working machine having a frame, a ground engaging wheel mounted to the frame and movable between a raised position not engaging the ground and a working position engaging the ground. The ground engaging wheel, when in the working position, rotating about a wheel axis as the machine is moved over the ground. An actuator raises and lowers the ground engaging wheels. A control system includes a sensor to detect rotation of the ground engaging wheel and a controller that receives an input from the sensor. The controller commands the actuator to raise the ground engaging wheel when the sensor detects that the ground engaging wheel is not rotating.

  • Publication number: 20110231069
    Abstract: An agricultural implement is provided that includes a ground engaging tool configured to engage soil in a working position and to disengage the soil in a non-working position. The agricultural implement also includes an actuating cylinder coupled to the ground engaging tool and configured to transition the ground engaging tool between the working position and the non-working position based on a flow of fluid from a fluid supply system. In addition, the agricultural implement includes at least one sensor configured to output a signal indicative of a fluid pressure within the fluid supply system, and a controller configured to determine whether the ground engaging tool is in the working position or the non-working position based on the signal.

  • Publication number: 20110186313
    Abstract: A dirt hole closer is attached to the front of a skid steer, or to a tractor, forklift, or the like and consists of a frame, a push blade, a left arm, and a right arm. The frame is removably attached to the lifting mechanism of the vehicle. The push blade, the left arm, and the right arm are attached to the frame and have coplanar lower edges. Both the left arm and the right arm can be manipulated, by means such as hydraulic actuators. The dirt hole closer provides a novel method of planting trees or setting posts or poles and utilizes both linear and angular motion to push excavated dirt into the annulus of hole surrounding the object being planted.

  • Patent number: 7540331
    Abstract: A soil working implement is dragged behind a towing vehicle. The implement includes a hitch part and a soil working part. The soil working part may be pivoted about the hitch part by extending or retracting a longitudinal linkage member interposed between the hitch part and the soil working part. Wheels are mounted on the implement and may be raised and lowered relative to the implement by an operator-actuated mechanism, to thereby permit the soil working part to be raised off of the ground by lowering the wheels to thereby facilitate movement of the implement from one treatment area to another, whereupon the wheels may be raised to permit the soil working part to engage the soil.

  • Patent number: 6293354
    Abstract: There is provided a disc unit for mounting a plurality of discs to an outer end of a mouldboard of a grader. The disc unit includes a mounting bracket for securing to a rear face of an outer end portion of the mouldboard. A frame is pivotally mounted on the mounting bracket and supports an axle which mounts the discs thereon. A hydraulic cylinder pivots the frame supporting the discs in relation to the mounting bracket for raising and lowering the discs to engage the ground at various depths of cut. A cushion valve releases the hydraulic cylinder in the case of an obstruction engaging the discs. The discs include a concave inner surface which are arranged to face towards the grader and partially in the direction of travel for urging particulate material away from the shoulder and towards a center of the road.
