A track type vehicle is provided with debris removal apparatus to prevent packing in a cavity defined by the track, the vehicle body, the drive sprocket, the idler and the frame member which mounts the drive sprocket and the idler. The debris removal apparatus is constructed in the form of a shaped plate whose peripheral edge conforms to the shape of the cavity and the plate is dimensioned such that the peripheral edge lies in immediate proximity of the cavity defining elements. In a normal or reset position, the plate lies immediately adjacent the body of the vehicle and in the operated condition, is moved outwardly by a plurality of hydraulic rams to push debris out of the cavity and prevent accumulation and packing. The plate may be further shaped, as viewed from the top, to include pockets for receiving roller supports which carry rollers for supporting the upper section of the track. Advantageously, the roller supports may include holes therethrough for receiving the piston rods of the hydraulic rams. |
