Built For The Track The Challenger MT800B-Transmission is designed and engineered to transfer the serious power of the Caterpillar® diesel engines to the ground-grabbing tracks. These are not converted from a wheeled tractor power train. They are the strongest, most durable and reliable transmissions in the industry. The powerful Caterpillar® diesel engines are coupled with the proven 16F/4R Power shift transmission, steering differential and final drives, designed specifically for the MT800B tractors . The power train delivers the optimum in rugged performance and durability, and every system is tested as a unit before it is installed in the tractor. Control of the engine, power train and hydraulics is integrated through a system of six on-board computers. These computers control state-of-the-art features like: - Intellitronics™,
- Power Management,
- One-Touch™,
- Auto-Guide™ and much more.
These rugged transmissions are built with heavy-duty cast iron housing, high capacity bearings and shafts for long-term durability . All gears are cut to provide maximum gear tooth contact with a minimum of noise. The transmission has nine individual clutch packs with seven rotating and two stationary clutches. Each of the 16F/4R gears is engaged when a combination of one range clutch and one speed clutch is engaged. The tractor will not “freewheel ” in any gear, and maintains constant speed, so the operator is always in control, even in the steepest gradients. Controlled Power The MT800B-Transmission electronic control and the electronic engine control, work together, linked through the Intellitronics™ network, to manage the shifting function. These electronic controls: - minimise shifting harshness,
- improving shift quality at any operating temperature, under all load conditions.
