John Deere X-Calibar II 4" Carbide Runners

John Deere X-Calibar II 4" Carbide Runners. Our most popular carbide runner. The 4" controlling cobalt carbide provides great steering control. A 7/16" bar with 1" tapered carbide wearpads at both ends provide extra wear resistance. Plus hardweld in back of the front pad, and in front of the rear pad substantially increases the wear resistance.
