Abstract: A grader vehicle has a vehicle body mounted on two drive tracks. A boom is mounted on the front of the vehicle and extends to the front of the body. A third drive track is mounted on the leading end of the boom by a steering mechanism for rotation about an upright steering axis. The three tracks are driven by separate hydraulic motors. The use of a steering, driven track on the boom provides a tractive force pulling the vehicle forwards in the desired direction of travel and positively driving the leading end of the boom in the direction of a turn. The track also provides a degree of packing at the center of the vehicle's path that can not be achieved with a ski gliding on the surface. This is of particular importance when packing ski trails with the vehicle. For grading purposes, the vehicle has a grader blade across the front of the vehicle and a second blade leading the front track.

The traveling mechanism has track frames (2, 2A) at right and left sides of the vehicle (1, 1A), track shoes (5, 5A) and drive units (6, 6A). The earth loading and ejecting devices are provided at the front and rear parts of the vehicle (1, 1A), and are installed to be vertically movable with lift cylinders (13, 33, 56, 78). Each of the earth loading and ejecting devices is provided with a scraper (21, 34, 53, 75) and a bowl member (14, 41, 61, 81) pivotably connected together by pivot pins (22, 42, 62, 83).

Abstract: Blade assemblies for use with compacting vehicles are normally designed to push the material in front of the blade and to control the height of the material passing thereunder for compaction by the compacting vehicle. With the blade raised to allow trash and/or soil to pass thereunder, the trash and/or soil passing thereunder may cause detrimental wear to the components under the compacting vehicle between the compacting mechanisms. In the subject arrangement, a blade assembly is provided and includes a blade pivotally connected to a frame. The blade has a working edge that permits, during use, level spreading of trash and/or soil when the blade is in a first operative position. When the blade assembly is raised and the blade is pivoted forwardly with respect to the frame, a first portion of the working edge controls the volume of trash and/or soil allowed to pass under the working edge between respective compacting mechanisms of a compacting vehicle.
