Challenger® Track Tractors MT851

MAN power

An incredibly smooth, quiet, high-torque-at-low-engine speed MAN power plant drives more power to the ground. With an RPM band ranging from 1,000 to 1,700 engine RPMs, and peak torque achieved from 1,000 RPMs.

AccuDrive CVT

The AccuDrive CVT transmission provides optimal coordination with the engine for peak performance and productivity across multiple applications.

A long wheelbase

The superior design of a long wheelbase with four sets of midwheels per side provides improved vehicle balance while distributing the tractor weight over a greater area, effectively reducing the deep compaction that restricts plant root growth.

AccuJoystick

Assign up to two preset cruise control and engine speeds to seamlessly adjust your ground speed with the easy-to-use Accu joystick.           

Cooler running

An independent, hydraulically controlled variable fan reduces power consumption and provides higher cooling capacity.

Smart Ride Plus (optional)

When equipped with Smart Ride Plus suspension, the MT800 Series features a load-leveling suspension system. With the push of a button in the cab, Smart Ride Plus uses hydraulic pressure in the track suspension elements to raise or lower the front of the machine.
