Connection attaching implement for crawler tractor consists of base plate on which pivots chassis, pair of connecting arms, and hydraulic drive

摘要

The attachment consists of a base-plate for fixing on the crawler tractor. Pivot mounted to the base plate is a chassis to which is hinged a pair of connecting arms, hydraulically driven. A third connecting piece is hinged to the chassis by a third axle running parallel to the second. Springs or rubber buffers restrict the pivot movement of the chassis in relation to the base plate. A rotary rod is between the two parallel side-pieces and supports a pair of lever arms. One of the lever arms is connected by means of a fixed connection to the appropriate connecting arm, and the other lever arm to its associated connecting arm by a connection which are adjustable in length.
