A guide arrangement for a track assembly of a track-type vehicle comprises a first arm mounted on a track frame, a second arm pivotally mounted on the first arm and a pair of rollers rotatably mounted on the second arm to engage the track assembly in rolling contact therewith. A pair of guides are secured to either the first or second arm to straddle each link assembly of the track assembly to restrain lateral movements thereof.

Track guiding means for a track-type vehicle

A resilient push dozer arrangement includes a push dozer transversely disposed at one end of a vehicle and a push arm rigidly secured to and extended from the dozer in juxtaposition to a longitudinally extending mounting frame of the vehicle. The distal end of the push arm is attached to the mounting frame through a device which permits limited longitudinal movement of the dozer relative to the mounting frame. An apparatus for cushioning the longitudinal movement of the push dozer toward the vehicle is provided so that the shock loads applied to the dozer are cushioned thereby and transmitted to the mounting frame at a point widely spaced from the attachment device.
