Abstract: A slopeboard mounting device having a rigid shaft that is attachable near a first end to a slopeboard frame and having near a second end a mechanism for indicating the desired location of a mounting lug. The rigid shaft has such a shape and size that the indicating mechanism is maintained at a desired position with respect to the first end of the rigid shaft which is the same position as is desired for a lug pivot point to have with respect to the slopeboard frame. And, preferably, the shape and dimensions of the rigid shaft are selected such that any obstructions are avoided by such rigid shaft.

Abstract: An exercise machine has a base with an upright member secured thereto. A pair of lever arms are rotatably positioned on the upright member and rotate from a first position to a second position. A gas cylinder assembly is mechanically associated with the upright member and connected to the lever arms by a chain means. The gas cylinder assembly provides resistance to movement of the lever arms from the first toward the second position. A purchase assembly is mechanically associated with the frame and connected to the lever arms by a cable means. The purchase assembly includes a block and tackle to provide a mechanical advantage for moving the lever arms from the first position toward the second position. A line from the block and tackle is connected to one of several possible moveable elements such that operation of the moveable element results in movement of the lever arms.

Abstract: A slopeboard mounting linkage that raises a slopeboard while also raising and moving a fluid-powered cylinder toward the longitudinal center of the bulldozer to which the cylinder and slopeboard are attached. One end of a rod extending from the cylinder is rotatably attached to the slopeboard as is also one end of a link arm. The other ends of the cylinder and of the link arm are rotatably attached to an angled link that is rotatably attached to the back of the primary push blade of the bulldozer. And the inside edge of the slopeboard is rotatably attached to a long arm of the bulldozer.
