With the launch of the MT800B Series, which now includes the awesome 570hp MT875B, Challenger further extends its lead as the producer of the world’s largest and most technically advanced tractors.

The MT800B Series features five models with increased power on every model and the new ‘flagship’ MT875B range topper, which at 570hp takes gross engine power to a new level among modern production tractors. The MT875B has the largest engine and highest power level in any production tractor – wheels or tracks.

No other manufacturer can match either the power or the sophistication of the new MT800B Series. These tractors are still the first, and only, machines built specifically for operation on rubber tracks. And the best is now even bigger and better.

“The MT Series set the benchmark providing new standards in agricultural tractor productivity,” says Andrew Rabett, Challenger General Product Marketing Manager for Europe, Africa and the Middle East.

“The new MT800B Series further extends performance and proves the commitment to on-going development of the Challenger products under AGCO’s ownership. This is matched only by Caterpillar’s advances in improving engine technology by not only developing the new ‘clean-burn’ ACERT™ engines, but also making them available to users a full year ahead of the imposition of the Tier III emission regulations. This simply serves to show just how far Challenger is ahead of the competition.”

All models are fitted with the latest Caterpillar ACERT™ engine, which not only meets forthcoming emission regulations, but also lift powers between 10hp to 20hp on the ‘B’ Series, compared with the previous models. It is also the first time an 18.1-litre engine has been used in a modern, production tractor.

This high capacity CAT® C18 ACERT™ unit generates 570hp (gross) in the MT570B and 510hp (gross) in the MT865B. The 15.2-litre capacity, C15 is now used MT835B (350hp), MT845B (400hp) and MT855B (460hp), replacing the C12 used previously in the smaller models. With a 42% torque rise and 8% extra power, the engines respond to changing conditions with plenty in reserve to pull through without the need to change gear.

These latest generation Caterpillar engines use ACERT™ technology to not only control emissions, but they also do this without sacrificing power, performance or reliability. On the contrary, it provides a power boost on all models. ACERT™ is not one single item, but a range of technology that produces better control of the combustion process.

ACERT™ employs cross flow cylinder head designs, four-valve per cylinders, waste gate turbo-charging and air-to-air after cooling. Fuel delivery is controlled precisely by CAT’s mechanically actuated, electronically controlled unit injectors (MEUI), which provide multiple injections and ‘rate shaping’ to ensure optimum combustion. All this is co-ordinated by the new ADEM 4 electronic control module (ECU). This is the most sophisticated unit of its type produced by the company and uses extremely fast and high capacity processing power for seamless integration of the engine, transmission, hydraulics and other components.

Up in the cab operators will not only appreciate the extra power, but also notice that the cab is quieter. Noise levels have been cut by 2.3dB(A), which is a significant reduction in intensity. Comfort is further enhanced with the option of semi-active seat suspension. This features 170mm of vertical travel with continuous automatic damping that responds to changing terrain.

The ‘Intelletronics’ system is improved and now allows operators to program the transmission to set any gear between one and seven in which to pull away, as well as the desired Power Management mode. This enables users to further tailor the tractor to the specific task, and both settings are retained in the memory after shutting down.

This setting will be shown on the Tractor Management Centre (TMC) screen. Also new on the TMC is a track tension monitor screen that shows, using two bar graphs, the actual pressure on each track. This addition is useful when working in difficult, sticky soil conditions or on hard bumpy ground. An alarm sounds to prevent damage due to over-stretching.
