Producers got their first look at the re-styled next-generation MT700 Series track tractors from Challenger at this year’s Farm Progress Show in Illinois. The company has added three new models to the lineup, offering 380 to 431 horsepower. They get that power from a new 9.8 litre diesel that hits peak torque in the 1,200 to 1,600 r.p.m. range. And it routes that power through a new transmission, the Accu-VT CVT.
Operators should notice a big difference in the ride with these machines. The new MT700 Series is the first to use three stages of suspension and oscillating mid-wheels that allow the tracks to better contour over the ground.
“The MaxxRide integrated comfort system consists of the oscillating mid-wheels, hardbar suspension and cab suspension, so operators experience great ride quality without sacrificing the in-field benefits of power, control and traction,” according to Josh Keeney, tactical marketing manager at AGCO, who led a walk-around of the tractor at the show. “Handling at higher road speeds also has been improved, and ride comfort when traveling on the road is noticeably better than previous models.”
The primary suspension has been redesigned with coil springs and high-capacity, off-road style shock absorbers to create the more comfortable ride, which the brand claims is superior to hydro-pneumatic suspension systems. A new two-point cab suspension system with increased suspension at the rear of the cab absorbs and dissipates the vibration from the ground through the rear axle.
There are also improvements inside the cab, starting with a new 10.4-inch touch-screen AccuTerminal that has a smartphone feel. Using the AccuTerminal, operators can manage all tractor settings and adjustments as well as monitor and control ISOBUS 11783-compatible implements. It also handles camera functions, field documentation, variable rate applications, guidance, wireless data transfer, and the AccuField Command headland management system.
All systems, including the hydraulics and PTO are designed to run at lower engine rpm, to further lower fuel costs and reduce engine wear, according to Keeney. An upgraded hydraulic system offers full output at just 1,700 r.p.m.
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. Porch lighting on the cab provides a safe view of the area, then the smart-battery disconnect powers everything down for the night. An integrated walk-around platform provides exterior cab access to help with jobs like cleaning windows.
