Caterpillar's agricultural commitment was demonstrated with the development of the Challenger tractor's rubber-belted track system more than 70 years later.
The Caterpillar Mobil-trac system provides excellent traction and flotation plus reduced compaction.
The undercarriage and belts are Caterpillar designed and manufactured to ensure quality, reliability and superior performance.
Each belt contains multiple layers of steel cable for precise tracking.
Four belt types and five belt widths match the best belt to the application.
The chevron driver features efficient mud and debris purging for excellent performance in all applications.
Debris shields on the roller frame prevent debris build up, keeping the drive wheel and reaction arm clean for maximum efficiency.
Differential steering provides smooth, full-power turns and outstanding maneuverability plus a turning radius unmatched in the industry.
The 32 inch (812.8 mm) diameter idler optimizes the bending angle of the belt to minimize rolling resistance and increase tractor efficiency.
The swing-link features sealed and lubricated bearings at the ends of both the pivot and the tension rod.
This self-supporting structure relieves the tractor frame of additional strain, and allows track spacing as wide as 120 inch (3048 mm) without undue component stress.
