ENGINE DETAIL
The Branson 6640C features a robust Kukje D3400NA diesel engine with a displacement of 3.4L, delivering 66hp at a rated RPM of 2600, which is optimal for medium-duty tasks and moderate workloads. Fuel efficiency at 2.4 gallons per hour could be advantageous for extended operational periods but may limit range compared to larger capacity models. A dry air cleaner and air heater pre-heating system enhance performance in dusty or cold conditions, though maintenance of these components is crucial for optimal engine longevity and efficiency.

TRANSMISSION
The Branson 6640C tractor features a syncro shuttle transmission with 24 forward and reverse gears, providing enhanced control during operations like loading and transporting. With a dry disc clutch, the tractor benefits from reduced maintenance compared to wet clutches, though it may require more precise engagement to prevent wear. This configuration is ideal for applications that demand frequent directional changes, such as in small farms or landscaping tasks.

MECHANICAL
The Branson 6640C features a robust 4x4 MFWD, enhancing traction and stability across diverse terrains, ideal for both agricultural and industrial tasks. Its hydrostatic power steering provides effortless maneuverability, while the 24-speed syncro shuttle transmission allows for precise speed control during varying load conditions. Key advantages include improved operator comfort due to the standard cab, but challenges may arise in maintenance complexity with the wet disc brake system, requiring regular inspection for optimal performance.

BRANSON 6640C TIRES
The Branson 6640C tractor features versatile tire options across agricultural, lawn/turf, and industrial applications, enabling it to adapt to various terrains and tasks. The ag front tires (12.5/80-18) paired with rear tires (16.9-28) provide a good balance of traction and stability for farming, while the lawn/turf setup (31x15.50-15 fronts and LSW570x648 rears) prioritizes ground protection and maneuverability on softer surfaces. However, choosing the right tire configuration is crucial; the agricultural setup excels in fieldwork, while the industrial configuration can enhance performance in construction and landscaping tasks but may compromise on field traction.
