ENGINE DETAIL
The Challenger MT862 tractor features a robust MAN D3876 turbocharged diesel engine with an impressive displacement of 15.3 liters, producing a rated power of 610.2 hp at 1730 RPM and delivering substantial torque of 2139 lb-ft at 1450 RPM, making it well-suited for heavy-duty applications such as large-scale agricultural tasks or construction projects. The 500-hour oil change interval facilitates maintenance efficiency, although operators should anticipate higher operational costs due to the engine's size and fuel consumption. Overall, its high torque output at lower RPM is advantageous for tasks requiring significant pulling power, but it may challenge maneuverability in tighter spaces or steep terrain.

CHALLENGER MT862 ENGINE
The Challenger MT862 features a robust MAN 15.3L 6-cylinder diesel engine, providing high torque and power for demanding agricultural applications. Its large 350-gallon fuel tank facilitates extended operational periods, while the 35.7-gallon DEF tank supports compliance with Tier 4 emissions regulations, enhancing environmental performance. The main considerations are the weight and space required for storage and transportation of such a large machine, which can limit its suitability for smaller farms.

TRANSMISSION
The Challenger MT862 features an Accu-VT continuously-variable transmission (CVT), providing seamless gear transitions without distinct shifts, enhancing operator comfort and reducing power loss. This infinite forward and reverse capability allows for precise speed control, making it ideal for varied field applications such as tillage or planting. However, the complexity of CVT systems can result in higher maintenance costs compared to traditional gear-driven transmissions.
