Challenger to launch MT800E Series tracked tractors at Agritechnica

Challenger is introducing its most powerful tracked tractor ever, the MT875E. Producing a rated output of 590hp, the new flagship generates a maximum power of 640hp (over 30hp more than the current MT875C).

Making its debut at Agritechnica 2013, the MT875E is one of the four new MT800E Series models. Superceding the MT800C Series, the new tractors benefit from the 12 cylinder 16.8 litre AGCO POWER™ engine.

Putting even more power to the ground through the Mobil-Trac™ system, this provides progressive farmers and contractors with higher levels of performance and efficiency.

Challenger MT800E Series:

Challenger MT800E features

• New 12 cylinder 16.8 L AGCO POWER™ Tier 4 Final / Stage IV engine

• New radiator design to improve cooling and simplify cleaning

• Improved geometry of steerable linkage system

• Optional high flow hydraulic pump with 321.8 lit/min capacity

• Improved operator comfort

New AGCO POWER™ V12 engine

The MT800E Series are the first tracked tractors in the industry to use the newly-developed AGCO POWER™ 16.8 litre, V12 engine. Developed and built at AGCO`s new production facility in Nokia, Finland, the new engine uses a combination of SCR and cEGR (Cooled Exhaust Gas Recirculation) to meet stringent Tier 4 Final / Stage IV engine emission regulations without the need of a Diesel Particulate Filter.

Working in a similar fashion to current Exhaust Gas Recirculation systems, cEGR differs in that engine exhaust gases are cooled before being mixed with air from the main intercooler.

Electronically actuated, and water cooled, as well as decreasing NOx levels, cEGR also reduces the amount of Diesel Exhaust Fluid (AdBlue) required during after treatment.

EPA regulations stipulate the components used in Exhaust After Treatment must last for at least 3,000 hours or five years, whichever comes first.

The new AGCO POWER™ V12 16.8 litre engine almost triples the requirements, the manufacturer confidently predicting an EAT components life of 8,000 hours.

New radiator design to improve cooling and simplify cleaning

Unlike the three banks of radiators used on the previous MT800C, the MT800E benefits from a new two-stage design. In addition to improved air-flow and cooling, the compact space saving format provides for easier access for cleaning.

Improved geometry of steerable linkage system

Challenger is the only tracked tractor available with a steerable rear linkage. Currently offered only on the three smaller models, in launching the MT800E Series the steerable rear linkage is also offered on the range-topping MT875E.

The latest version features a new design and positioning of the steering cylinders. Resulting in an improved steering angle, this leads to better control and stability in wet and dry conditions.

Optional high flow hydraulic pump

The standard 220 lit/min oil flow from the current range has been retained, but all MT800E Series tracked tractors are available with an optional 321.8 lit/min system.

The higher oil flow leads to faster operation when working with wide hydraulically-operated implements.

Improved operator comfort

In addition to a smoother shifting transmission, Challenger is also introducing other refinements on the MT800E Series to further improve operator comfort, boost performance and increase durability.

The MT845E and the MT855E are fitted with the Air Ride Seat, but the Deluxe VRS seat with fabric cover (leather optional) from the current top model is standard on both MT865E and MT875E.

In addition, all four tracked tractors can be specified with the Deluxe VRS vented leather seat. This luxurious option features an in-built heating and cooling system to take operator comfort to a higher level.

AutoGuide 3000™ is a new, integrated and affordable system, which is designed to provide agriculture professionals with the highest levels of accuracy. This latest generation provides easy to use, ‘plug and play’ operation and is fully scalable from sub-meter to centimetre accuracy.

The new guidance option operates directly from the 7.4” Tractor Management Centre Display, eliminating the need for an additional screen. It is also possible to engage guidance through the One-Touch™ headland management system.

A natural evolution of the popular MT800C Series, the new four model MT800E Series goes into production next spring with first deliveries expected in Europe by the summer.
