Abstract
Abstract 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.
