Abstract: The hydraulic cylinder and line guard of the claimed invention substantially surrounds and protects both a hydraulic cylinder and portions of a hydraulic line. The guard also significantly reduces the visual appearance of the hydraulic lines. While maintaining the flexibility of the hydraulic lines at pivot points, the guard inhibits movement of the line near the cylinder thereby reducing wear on the line. The claimed invention also achieves the important objective of providing an aesthetically pleasing and easily replaceable guard for hydraulic cylinders and lines. The improved guard is achieved by utilizing a resilient guard to cover both the cylinder and the line. The guard may be formed from a single stretchable resilient tube that is deformed to enclose both the line and the cylinder, wherein a cross-section of the guard is defined primarily by combined cross sections of the cylinder adjacent to the line.

Abstract: A hand-operable connection assembly is described for quickly connecting and disconnecting a vehicle from a boom assembly. The connection assembly includes a tower and a bracket, the tower is rotatably secured to both an actuator and a boom arm while the bracket is secured to a vehicle or construction device. The tower and bracket interconnect via pins that seat in pockets, and the tower is secured or locked to the bracket via a hand-operable locking clevis that rotates about one of the pins and wraps around the curved exterior of one of the pockets. The center point of the exterior curvature is offset from the center point of the clevis rotation such that rotation of the clevis tightens the clevis against the pocket. The pins may be located at the two hinges connecting the boom arm and actuator to the tower, or the pins may be separated from the hinges. The exterior of the pocket may include a grind sheet designed to scrape against and secure a grind bar of the locking clevis in a locked configuration.

Abstract: A material-handling bucket which includes a blade with scarifying teeth on the rear of the bucket. By raising the bucket and rolling the bucket backward, the blade and teeth can be made to engage the ground to provide grading and scarifying capabilities for a conventional loader bucket. The blade and scarifying teeth, however, do not interfere with the normal loading operations of the bucket.
