GRAND ISLAND, Neb. — Challenger, a global brand of AGCO Corp., launched the MT400E Series tractors. The five new models offer max engine horsepower ratings from 120 to 160 and the choice of three transmission options, including the TechStar (CVT).

They are ideal for all-around use on livestock and row-crop operations. Models include the MT455E (120 hp), MT465E (130 hp), MT475E (140 hp), MT485E (150 hp) and MT495E (160 hp).

“Customers who have previewed these tractors have been impressed with the range of operator conveniences available from tractors with this level of power, stability and lift capacity. With features such as our optional industry-exclusive multi-function joystick and three transmission options, many customers are finding the MT400E Series offers the right combination for their operations,” said Eric Zimmerman, AGCO tactical marketing manager.

“These are big mid-range tractors ideal for someone who wants to run a large round baler or a mower conditioner or pull mid-size planters and tillage equipment.”

The MT400E Series tractors boast a base weight of 15,432 pounds and maximum loader lift capacity of 5,032 pounds at the pivot pin. An optional, factory-installed live third function enables up to three loader functions simultaneously to make loader work even easier.

“Dairy producers are constantly unloading and loading feed, hay or other material,” Zimmerman continued. “With the multi-function joystick, loader work is much easier and more efficient because an operator can control the loader, as well as move the tractor backward and forward with one hand.”

Power plant

The Challenger MT400E Series tractors are powered with a 4.9L AGCO Power 4-cylinder diesel engine meeting EPA Tier 4 Final emission standards using Selective Catalytic Reduction — meaning no diesel particulate filter, no regeneration requirements and no exhaust gas recirculation system.

The engines breathe intercooled intake air provided by a new turbocharger equipped with an electronic wastegate and are fed by a 29,000 psi fuel injection system. The engine service interval is 600 hours.

A new Vistronic engine-cooling fan automatically adjusts air flow through the radiator depending upon operating conditions, a feature that also improves engine brake efficiency by 15 percent over previous models.

To enable the MT400E Series to stay in the field working longer, engineers have included a 54-gallon fuel tank and a 7.9-gallon secondary Diesel Exhaust Fluid tank.

To efficiently deliver power to the ground and obtain the most productivity from every gallon of diesel fuel, AGCO engineers have equipped the MT400E Series with Engine Power management. This advanced electronic engine and transmission management system adjusts to provide more fuel when operating conditions require it.

Each of the three transmission choices includes EPM. They are:

n The TechStar CVT, a true continuously variable transmission with no clutch packs, capable of road speeds up to 31 mph.

n The AutoPower VI, 24F/24R Semi-Powershift with four ranges and six Powershifts per range and road speeds up to 31 mph.

n The standard AutoPower IV, 16F/16R Semi-Powershift with four ranges and four Powershifts per range with a max road speed up to 25 mph.

“The Power Management system operates automatically without operator involvement,” Zimmerman said.

The MT400E Series uses a proven front axle with QuadLink suspension, fully adjustable from the cab. The linkage has 4.5 inches of travel and is controlled by a single hydraulic cylinder and accumulator mounted in the axle housing.

Cab suspension for the MT400E Series tractors includes regular mechanical suspension or an optional active mechanical system that allows dampening forces to be increased from the cab, on-the-go, up to 15 percent in the field and 30 percent on the road.

Ergonomically designed cab controls keep operator efficiency high with a multi-function joystick for tractor operation. Also, well-designed pillar controls and a 50 percent larger, brightly lighted, multi-colored digital Setup and Information Screen and analog center dash control display help the operator monitor system functions and manage the hydraulic system.

In addition, the MT400E Series offers optional Fast Steering, allowing the operator to adjust the steering ratio for more or fewer turns of the steering wheel so loading and headland turns are faster and easier.
