ENGINE DETAIL

The Challenger MT655C features a robust AGCO SISU POWER 84CTA turbocharged 6-cylinder diesel engine with an impressive power range of 265hp to 295hp and a torque output of 955 lb-ft at 1500 RPM, making it suitable for heavy agricultural tasks. The engine's Interim Tier 4 emissions compliance, achieved through an e3 SCR system and optional IEGR, enhances environmental sustainability, though it may increase maintenance complexity due to the additional components. Its high-pressure common rail fuel system ensures efficient combustion, potentially yielding better fuel economy under load; however, operators should be aware of the need for quality fuel to maintain performance.

CHALLENGER MT655C ENGINE

The Challenger MT655C is powered by the AGCO SISU POWER 8.4L 6-cylinder diesel engine, delivering high torque for demanding tasks, and can operate efficiently under heavy loads. Its substantial fuel tank capacity of 155.9 gallons (590.1L)—or 182.3 gallons (690.0L) without SCR—enables extended operation periods, making it ideal for large agricultural projects. However, with a 7.9-gallon (29.9L) DEF tank, operators must monitor fluid levels closely to comply with emissions standards, particularly during prolonged use.

TRANSMISSION

The Challenger MT655C features a Techstar Continuously Variable Transmission (CVT) that provides infinite gear ratios for seamless power delivery and enhanced fuel efficiency. This design allows for smooth acceleration and deceleration, reducing operator fatigue during long hours of operation. However, the complexity of CVT systems may lead to higher maintenance costs compared to traditional gear transmissions, particularly in heavy-duty agricultural applications.

CHALLENGER MT655C TRANSMISSION

The Challenger MT655C features a continuously variable transmission (CVT), providing seamless power delivery and enhanced fuel efficiency through optimal engine speed management. This system allows for smooth acceleration and deceleration, making it ideal for applications requiring precise speed control, such as tillage or planting. However, the complexity of CVT can lead to higher maintenance costs and potential durability concerns under extreme conditions, necessitating careful operational practices.

MECHANICAL

The Challenger MT655C features a four-wheel drive system and electro-hydraulic differential locks, enhancing traction and stability on varied terrains, particularly beneficial for heavy-duty applications like tillage and hauling. Its hydraulic wet disc brakes provide superior stopping power and are less prone to fade compared to traditional brakes. The cab's climate control options improve operator comfort, making it ideal for long hours in the field, although the additional features may increase overall costs.

CHALLENGER MT655C TIRES

The Challenger MT655C tractor features a robust tire configuration with 480/70R34 at the front and 520/85R46 at the rear, enhancing traction and stability on various terrains. This setup is advantageous for heavy tillage and planting operations due to its larger rear tires, which provide better flotation and reduced soil compaction. However, the tire differences may introduce challenges in handling during sharp turns, necessitating careful operation to maintain maneuverability.

DIMENSIONS & TIRES

The Challenger MT655C features a 122.2-inch wheelbase, enhancing stability during heavy-duty applications. Weighing between 24,250 to 25,795 pounds, it offers substantial traction for various terrains, while the combination of front 480/70R34 and rear 520/85R46 tires maximizes floatation and reduces soil compaction. Ideal for large-scale farming operations, its robust frame is advantageous for towing and fieldwork, but users should consider the weight when maneuvering on softer ground to avoid sinking.
