Growers looking for ways to improve engine fuel efficiency and get more of that horsepower on the ground will find the answer in a new series of Challenger track tractors that does all of that and meets the latest emission standards.

Challenger, the original track tractor, has recently introduced a new MT700D series that is available in two models and designed to take on the most demanding jobs in the ag environment. The new models are powered by the AGCO POWER 8.4L diesel engine and equipped with the exclusive Mobil-trac system that designed to put more power to the ground.

"AGCO POWER engines are not just an ordinary power plant for a tractor," said Carlton Self, product marketing specialist for high-horsepower tractors. "The manufacturing process for these diesel engines relies on an industry-exclusive assembly process which allows us to work to exacting standards. The process includes precision balancing of the cam shaft, connecting rods and bearings to the nearest gram, which reduces vibration, optimizes engine performance and extends service life."

The AGCO POWER 8.4L diesel in the model MT765D is rated at 285 PTO and 350 engine horsepower and the model MT755 is pegged at 260 PTO and 327 engine horsepower. Both engines provide low operating input costs, low noise levels, long life and uncompromised power and torque. In fact this engine will sustain a higher level of torque throughout the RPM spectrum, according to Self.

Tier 4i emissions standards are met with the industry-leading AGCO e3 clean-air technology that allows maximize power output while minimizing exhaust treatment costs by varying the diesel exhaust fluid (DEF) rate based on real-time emission measurements.

The engine features a single-piece cast iron block with wet cylinder liners, which enables the engine to handle high horsepower loads without overheating, thereby extending its service life. As a way of maximizing fuel efficiency, four valves per cylinder are featured in this engine as well as a new pump and injectors. In addition, increased common rail pressure and SISU electronic controls help maximize engine efficiency.

The new Challenger series track tractors also feature the exclusive Mobil-trac five axle undercarriage system with oscillating mid-wheels. This unique design minimizes soil compaction while maximizing traction and pulling power in even the most demanding environments, Self noted.

Standard polyurethane mid-wheels provide longer life in abrasive environments and where long transport distances are required. Gauge settings, ranging from 72 to 160 inches, plus a wide selection of track widths, allow these tractors to fit the needs of a wide range of farming operations.

Attention has also been given to improving operator comfort and visibility in the new Challenger series track tractors. The spacious 110 cubic feet of space in the cab provides for unparalleled visibility and operator comfort, which only enhances the already smooth, industry-leading Mobil-trac ride.

Other features include a 59 gallon per minute (GPM) hydraulic pump option and 37 GPM flow per hydraulic remote designed to provide the hydraulic capacity needed for large planters and tillage equipment.

These tractors are built by the experienced manufacturing team at the Challenger tractor facility in Jackson, Minn., and are supported by a dealer network that provides unparalleled support and parts availability to ensure maximum uptime.
