The sixth generation of Challenger’s 700 series of tracked tractors packs more power, fuel efficiency and operator comfort than any other tracked machine on the market.

AGCO introduced the redesigned MT700 to media at its Jackson, Minnesota, manufacturing facility on July 20.

The MT700 series—available in 380, 400 and 430 horsepower iterations—features new styling that looks downright sleek. That package covers an entirely new AccuDrive powertrain, featuring AGCO Power 9.8L diesel engines mated to the Challenger Accu-VT continuously variable transmission for smooth, seamless speed control. The engines are cooled with a unique “concentric air system,” in which the radiator and cooling fan are aimed slightly upward, pulling cooler, clean air.

The combination results in a high-torque, low-speed approach, which allows the Challenger MT700 Series tractors to run in the maximum torque range while delivering low fuel consumption to help increase productivity and reduce costs.

All systems, including the hydraulics and PTO, are designed to run at lower engine rpm, to further lower fuel costs and reduce engine wear. The upgraded hydraulic system offers greater flow at lower engine rpm and the capabilities to meet the demands of the latest planters and implements. Now instead of running at full throttle to meet the hydraulic needs, the AccuDrive system allows full output at 1,700 rpm. Not only does this allow for the tractor to run in the peak torque range of 1,200 to 1,600 rpm, but it also does so more efficiently with less engine wear. This system also results in a quieter working environment for the operator. 

Unique suspension

The Challenger MT700 Series is the first two-track machine with three stages of suspension and oscillating midwheels that precisely contour to the ground over terraces and uneven surfaces.

Called MaxxRide, the integrated system includes oscillating midweels, hardbar suspension and cab suspension to improve ride quality without sacrificing power and traction.

“Handling at higher road speeds also has been improved, and ride comfort when traveling on the road is noticeably better than previous models,” said Josh Kenney, tactical marketing manager at AGCO.

The primary suspension has been redesigned with rugged coil springs and high-capacity shock absorbers for a more comfortable ride compared to hydro-pneumatic suspension systems. Offroad style, heavy-duty shock-absorbers provide precisely tuned digressive damping. 

All new cab

Operators will note a number of amenities, including air-ride seat, larger instructors’ seat and Bluetooth capability.

At the right of the operator’s seat is a 10.4-inch touch-screen AccuTerminal, through which users can manage all tractor settings and adjustments, plus monitor and control ISOBUS 11783-compatible implements, camera functions, field documentation, variable rate applications, guidance and wireless data transfer, and the AccuField Command headland management system. The Advantage armrest, AccuTerminal, Advantage joystick, PTO controls and conveniently color-coded keypad are all within easy reach of the operator’s fingertips.

A new LED light package adds more lights at the rear of the tractor, positioned to provide a clear view out to each end of a 24-row planter for those late nights in the field. When leaving the field after a long day, porch lighting on the cab provides a safe view of the area, then the smartbattery disconnect powers everything down for the night.

These tractors connect with AGCO’s entire suite of Fuse Technologies and Fuse Connected Services for the latest in guidance, precision farming and remote monitoring technology.

Furthermore, they can be equipped with automated steering products from NovAtel and Trimble. 


A limited number of MT700 series tractors will be available this fall, with full production in 2018. The manufacturer suggests base prices range from $362,000 for the MT738 to $386,000 for the MT743.
