Abstract: A mounting bracket is provided for the support or idler rollers for the upper run of a track vehicle. The bracket includes two sets of teeth on opposite sides of the roller in order to scrape and remove mud and debris. Preferably, the bracket includes mounting wings that extend downwardly at an approximately 45-degree angle and with the teeth extending substantially tangentially to the outer support surface of the roller. The roller extends down into a cut-out opening between the wings and the teeth that are formed integrally along the upper edges of the wings. Flat bridge portions of the plate receive the bearing pillow blocks of the roller.
