Challenger® Track Tractors MT738

AGCO Power™ Engine

The highly efficient 7-cylinder engine was improved with a high-torque, low-engine-speed concept that delivers 1,400 ft./lbs. of torque at 1,275 RPM — perfect for heavy draft work. The engine, transmission, fan and hydraulics are precisely engineered to work at their highest capacity at these low engine speeds.

Accu-VT™ Transmission

The transmission provides optimal coordination with the engine for peak performance and productivity across multiple applications. During field operations, torque is transferred flexibly, resulting in tremendous pulling power. The continuously variable operation allows for 65 ft./hour to 25 mph all in one range without any intervention by the operator.

Concentric Air System (CAS)

A high-performance fan located in front of the cooler unit sucks in cold, dense air, accelerates it over the concentrically formed hood and presses it through the radiator. The CAS has its own hydrostatic drive, delivering ideal cooling power to each component — according to need — independent of engine speed.

Mobil-Trac™ System

Challenger’s legendary Mobil-trac system has been enhanced with a longer wheelbase at 101 in. (257 cm). Its unique pivoting tri-bogie mid-wheels keep the tractor in constant contact with the ground for better traction, more pulling ability, greater fuel efficiency and a smoother ride. The design also improves vehicle balance, while distributing weight over a greater area, in effect reducing the deep compaction that restricts plant root growth.

Accu-Terminal

All operating tasks and functions are right at your fingertips, including the Advantage joystick, PTO controls, hydraulic fingertip valves and more. You save time, plus distraction and fatigue are minimized.

Two-Point Cab Suspension

The cab suspension consists of two rugged coil-over shock absorbers, which provide a significant comfort advantage for the operator. Ground vibrations, typically transmitted by the rear axle during rough roading or field conditions, are greatly reduced. This innovative suspension allows a full 4 in. (100 mm) of travel at the rear of the cab, absorbing and dissipating the jarring ground vibrations you encounter with standard or quad-track systems.
