AGCO Corporation unveiled its latest entry into the track tractor category this week, the Challenger MT700 Series featuring 3 models ranging in power from 380 to 431 hp.
The MT700 models feature an industry-first three-stage suspension system, making for a smoother ride both in the field and on washboard gravel roads. “Operators are going to notice a significant difference in ride comfort—one they won’t find on other track tractors of any color,” says Josh Keeney, tactical marketing manager for AGCO.
The three-stage suspension includes a mobile track system with pivoting mid-wheels in the three-wheel bogey configuration, heavy duty shock absorbers and springs and enhanced cab suspension. The Tri-Bogie suspension system provide better track-to-ground contact, which in turn provides more stability and comfort in the cab. The tractors also have a re-designed MobilTrac System, which moves the hardbar further forward. That, in turn, creates a longer wheelbase and more stability.
The MT700 models are powered by 9.8 liter diesel engines, designed to work at lower RPM to provide optimal torque while consuming less fuel and reducing engine wear. The powertrain continues to feature AGCO’s continuously variable transmission, which creeps from 65’/minute to a road speed of 25 mph. The hydraulic system is designed to operate at engine rpm speeds of 1,200 to 1,600, again to provide optimal torque and fuel efficiency. This lower engine speed also provides a quieter working environment for the operator, says Keeney.
The cooling system in the MT700s have also been redesigned. Instead of standing vertically, the system is tilted up and back so that it pulls in the cleanest possible air for cooling. Fans are also driven by hydraulic motors, and are no longer tied directly to the engine. That allows fans to be operated independently at just the right speed to drive air through the radiators to increase efficiency.
A new LED lighting system allows operators to “light up the night,” especially important when performing critical field operations late into the evening. The lighting package is positioned to provide clear night-time views to reach out to the ends of a 24-row planter. The lights can also be selectively dimmed so they don’t blind a combine operator, for example, when the tractor is pulling a grain cart for on-the-go unloading.
The new cabs of the MT700s also have unique, integrated walk-around outside platforms for easy cleaning of all windows if the farmer decides not to install a side washer/wiper system. The tractors also come equipped with a full package of auto-guidance.
The suggested retail price of the tractors range from $362,000 to $386,000. A few units will be available yet this year, but full production will start in the first quarter of 2018, says Sweeney. The tractors will get their first public viewing at farms shows this fall. Learn more at http://www.challenger-ag.us.
