Better Performance on Track
There isn’t a better value for money Site tractor on the market than the MT800B Special Application tractor - the exclusive Mobil-tracTM system combines the speed, mobility and versatility of rubber tyres with the traction, flotation, smooth ride and low ground pressure of tracks.

At 3000 mm (118.1 inches) between axles, the Mobil-trac unit is the longest twin rubber-tracked tractor in the industry. This improves balance and traction; whilst offering a shorter turning radius than any articulated tractor.

The Opti-RideTM suspension also absorbs ridges, bumps and ruts like no other system on the market. High-tech rubber/fabric springs between the hardbar and chassis cushion shocks to the operator. A stabiliser bar allows the individual tracks to oscillate and suspended midwheels smooth the ride by moulding to the ground surface, cushioning the impact while improving traction.

Adaptable To Your Specific Needs
A wide choice of undercarriage options allows you to tailor a Challenger MT800B Series Special Application tractor to fit your specific operation, no matter the conditions.

Three belt widths and two treadbar designs put more power to the ground thanks to treadbars, guide blocks and track carcasses that are created from specialised rubber compounds designed
to resist abrasion and wear.

Extreme Application Belt
Designed to handle heavy road travel, steep side slopes or abrasive traction conditions, they feature a thick carcass to resist abrasion from stones; tall tread bars for longer wear life and traction; and long guide blocks.

Special Application Belt
Designed for harsh environments and operations, these belts feature 63 mm (2.5-inch) tall tread bars, 13 mm shorter than those used on extreme application belts. This helps reduce tread bar flexing and irregular wear on compacted and unbroken soils and improves cleaning. The belt carcass is also thicker, with two additional layers of rubber added to the inner belt surface.
