CMI C400 Mulching Tractor

A high-drive system with the torque to match.

Built for sustained production, the C400 combines high-drive clearance, torque, and stability for large-scale clearing operations.

Industry-leading clearance keeps the machine moving.

Conventional undercarriages are vulnerable to debris buildup. The C400L isn’t. With 25 inches of ground clearance, critical moving parts stay above the debris line, protected from buildup and contamination. The result is sustained speed and continuous operation in harsh conditions—a high-drive design proven for decades in demanding pipeline work.

Engineered for large-scale operations.

At the core of the C400 is a Cummins L9 engine that delivers 1,324 lb-ft of torque. That power is supported by CMI’s proven dozer-design track frame and a D4 sealed and greased undercarriage built for demanding, continuous work. An efficient hydraulic system channels engine output into steady, controlled mulching performance—maintaining torque under load and consistent cutting power through dense vegetation, heavy material, and large-scale clearing applications.
