MT800C Series


Track Tractors

The MT800C Series is the only high horsepower track tractor that can be configured to accommodate row-crop work or be equally at home pulling large tillage tools and air seeding applications. The powerful engine, combined with a proven transmission, is only part of this highly productive yet versatile track tractor. The MT800C Series has the flexibility to match virtually any soil type or farming practice.

The MT800C Series also offers the ultimate in comfort, convenience, and control. When you consider the proven Mobil-trac™ undercarriage system, the simplicity of the Tractor Management Center with controls at your fingertips, and the spacious climate-controlled cab, you’ll quickly discover that these tractors are as comfortable as they are powerful.

The Tier III Cat® C15 and C18 ACERT® technology engines supply significant power when compared to other tractors in its class. The real test of an engine is when it maintains power, while lugging through tough conditions and encountering heavy loads. The MT800C Series models have the built-in deep torque reserve that today’s farmers demand.



While most engine manufacturers resorted to other methods to meet Tier III standards, including exhaust gas recirculation (EGR), Caterpillar took a completely different path, developing its own unique technology. ACERT technology allows precise control of the combustion process ensuring emission standards compliance without sacrificing horsepower, performance, or reliability.

  • 923 cubic inches (15.2 L) and 1,106 cubic inches (18.1 L) displacement
  • 42% torque rise
  • Peak torque is reached at 1,400 RPM.
  • A more efficient fuel system achieves maximum fuel economy and lower emissions.
  • Mid-support of the cylinder liners decreases vibration, reduces engine noise, and reduces power lost by piston blow-by.

Built from the ground up solely for use on the Challenger track tractor, the CAT Powershift transmission features push-button control for all 16 forward and 4 reverse gears.

With eight gears providing a 4 to 9.3 MPH (6.5 to 14.9 kph) working range, the MT800C Series provides the responsiveness and productivity your applications need. Since getting the job done means being in the field, Challenger offers one of the fastest transport speeds of any other track tractor at 24.6 MPH (39.6 kph) meaning more time in the field and less time on the road.

The CAT transmission and engine are continuously communicating to provide optimum productivity and performance. The transmission senses the load on the engine and adjusts to deliver smoother shifts and longer life for all components.

Power Management (PM)

The Power Management system is designed to get the job done faster and more efficiently.

This control coordinates engine speed with transmission gear to match an operator’s needs with field conditions. Maximum Power mode keeps the engine in the peak power range for heavy draft loads. Constant Ground Speed achieves an operator-designated ground speed while automatically controlling shifts and engine speed to maximize fuel efficiency.



Challenger MT800C Series tractors offer more flow, more versatility, and more efficiency than ever before.

Standard features include 4 remote hydraulic valves with a 5th and 6th valve available as an option. The MT800C Series feature a closed center, load-sensing, pressure- and flow-compensating system, a 43.5 gpm (164.7 L/min) pump standard, and a 59 gpm (223.3 L/min) pump option.

The operator can electronically adjust flow rates, timed detents, and individual valve operation with precision from the cab’s Tractor Management Center display. The operator can also direct continuous flow of up to 36 gpm (136.3 L/min) through any one coupler. This is particularly important in seeding and planting applications where uninterrupted oil flow to hydraulically driven motors is critical.

Operator Area

Operator Area

One of the first things you’ll notice about the cab is its size. Leading the industry, it boasts 108 ft3 (3.06 m3) of comfort, convenience, and control.  You’ll appreciate the 67.5 ft2 (6.2 m2) of usable glass area, the slim profile dash, and the short sloping engine hood which combine to deliver an unobstructed, panoramic view.

Additional comfort and convenience amenities include: 

  • An optional VRS semi-active, heated operator’s seat that provides continuous real-time automatic damping force in response to varying terrain.
  • An electronic dash showcasing all major tractor and engine functions, including the selected gear, engine RPM and machine hours.
  • The Surround-Flow™ ventilation system keeps you comfortable and productive with 12 vents strategically placed throughout the cab.
  • Optional Nightbreaker HID lighting provides clear definition of detail from a greater distance than normal halogen lights.
  • The largest and most comfortable instructor’s seat in the industry is standard, but can also fold down and double as a workspace to use your laptop.

Tractor Management Center (TMC)

Challenger’s unique Tractor Management Center (TMC) has an intuitive ergonomic design that puts all key functions at your fingertips including the all new ISOBUS TMC display. As the international standard for electronic communications used in agriculture, ISOBUS allows any compatible tractor to communicate with any compliant implement, no matter the manufacturer.

The TMC display allows the operator to monitor all tractor, engine, and transmission functions, as well as check and adjust hydraulic flow settings all from one single location. It can control all connected ISOBUS compatible implements - eliminating the need for additional monitors or control boxes in the cab. Simply plug and play for seamless operation.

Mobil-trac™ system

Mobil-trac™ system


Challenger’s exclusive Mobil-trac system (MTS) combines the speed, mobility, and versatility of rubber tires with the flotation, traction, and low ground pressure offered by tracks.  The superior traction and floatation provided by the MTS gives you more pulling ability, greater efficiency, and a smoother ride to let you do more per day.


Thanks to the exclusive Opti-Ride™ suspension, advanced Marsh Mellow® springs, and oscillating bogey system, the MTS can adapt and contour to the varying field terrain, isolate and absorb any bumps and ruts, and provide the operator a smooth comfortable ride..


Easily adjusting the infinitely variable undercarriage gauge, which ranges from 90-128 inches (2286-3215 mm), allows the Challenger MT800C Series tractors to fit virtually any farming operation. With the widest selection of belt offerings available, Challenger provides the flexibility to match any cropping operation and efficiently put the power to the ground.
