    摘要： The invention provides a skid steer rake capable of adjustment and modulation during use, without any need to halt operation of attached machinery. The skid steer rake is configured with a plurality of scarifiers capable of deployment and retraction during course of use of the device, as well as a landscape rake and a plurality of clod-cleaving wheels. The scarifiers can be latched in various positions depending on the user's needs. The skid steer rake can be operated in a push or pull configuration, if necessary. Another embodiment of the skid steer rake is configured to have clod-cleaving wheels adjustable to the uneven terrain while maintaining contact of the scarifiers and the skid steer rake with the ground surface.

    摘要： A tool bit includes a shank portion defining a longitudinal axis, a free end, and a perimeter, at least one anti-rotation feature on the perimeter extending to the free end, and a cross-hole defining a cross-hole axis along which the cross-hole extends through the shank portion. The tool bit also including a working portion extending downwardly axially from the shank portion. The working portion includes a rear region, a front working region defining a width with a midpoint, a first side region and a second side region. The first side region and the second side region define an angle of extension measured in a plane perpendicular to the longitudinal axis. The cross-hole axis pass through the width of the front working region when projected onto a plane perpendicular to the longitudinal axis.

    摘要： A system, method, and apparatus includes measuring wear of a cutting edge of a blade of a work vehicle. Blade position or calibration measurements are made with or without a cutting edge. A wear condition of the cutting edge is acceptable when the blade position measurement less an acceptable wear to the cutting edge amount is less than a blade calibration measurement. A wear condition of the cutting edge is unacceptable when the blade position measurement less an acceptable wear to the cutting edge amount is greater than a blade calibration measurement. Alternatively, a wear condition of the cutting edge is unacceptable when a blade calibration measurement plus a tolerance margin is greater than the blade position measurement. The wear condition of the cutting edge is acceptable when the blade calibration measurement plus a tolerance margin is less than the blade position measurement.

    摘要： A blade for a work vehicle may include a front wall, a back wall, a first support, a second support, and a third support. The front wall may be for engaging material to be moved. The back wall may be positioned at a distance from the front wall. The first support may be positioned between the front wall and the back wall and connected to the front wall and the back wall. The second support may be positioned between the front wall and the back wall and connected to the front wall and the back wall. The third support may positioned between the front wall and the back wall and connected to the front wall and the back wall.
