MECHANICAL
The Challenger MT855E is equipped with a crawler drive system, offering superior traction and stability on uneven terrain, making it ideal for heavy tillage or hauling applications. Its power differential steering enhances maneuverability, which is advantageous in tight spaces or during field turns, although it may require more skill to operate effectively compared to traditional steering systems. The standard cab with air-conditioning increases operator comfort during extended use, but may also add weight, impacting overall agility in certain field scenarios.
