ABSTRACT:
A roller frame for a crawler tractor for supporting the body portion of the tractor and including a pair of laterally spaced and parallel side rail members rigidly interconnected to form an elongated unitary member. Each of the side rail members have an upper edge and a lower edge with the latter having at least two generally U-shaped cut-out portions formed therein so as to provide a front support surface, an intermediate support surface, and a rear support surface. A plurality of rollers are adapted to be supported in each of the cut-out portions and a shield extends between each adjacent pair of support surfaces and is fastened thereto so as to enclose the lower portions of the rollers and prevent rocks and the like from gaining access into the roller frame.
