ENGINE DETAIL
The RK Tractors RK37HC, powered by a liquid-cooled Yanmar 3TNV88-CR diesel engine, offers a gross power output of 37.4 hp at a rated RPM of 3000, ideal for moderate agricultural tasks. Its common rail direct injection fuel system enhances fuel efficiency and reduces emissions, making it advantageous for environmentally conscious operations. However, users should be aware that the limited displacement of 1.6 L may affect performance under heavy loads, particularly in demanding field conditions.

RK TRACTORS RK37HC ENGINE
The RK37HC features a Yanmar 1.6L 3-cylinder diesel engine renowned for its fuel efficiency and torque delivery, ideal for compact utility applications. With a 9-gallon (34.1 L) fuel tank, it offers a practical range for extended operations in agricultural tasks, minimizing downtime for refueling. However, the relatively small engine displacement might limit power in demanding conditions compared to larger competitors, making it better suited for light to moderate workloads.

TRANSMISSION
The RK37HC tractor features a hydrostatic transmission, providing seamless, infinite speed control within its 3-range (forward and reverse) gearing, allowing for precise maneuverability in various agricultural tasks. This configuration enhances operator comfort and reduces fatigue, as it eliminates the need for clutch engagement during operation. However, hydrostatic systems can be more complex and may require higher maintenance compared to traditional gear-driven setups, making them potentially costlier in the long run.

| Gears | infinite (3-range) forward and reverse |
MECHANICAL
The RK37HC features a 4x4 MFWD system for enhanced traction in varied terrain, ideal for tasks requiring stability on uneven ground. Its hydrostatic transmission allows for smooth, variable speed control, which is advantageous for precision work such as loader applications. Equipped with a standard air-conditioned cab, the operator benefits from increased comfort during extended usage, although the maintenance of the air-conditioning system may add to operational costs.

RK TRACTORS RK37HC TIRES
The RK37HC tractor features versatile standard agricultural tires (7-16 front; 11.2x24 rear), optimizing traction and stability for fieldwork. The option for turf tires (28x8.5-15 front; 41x14-20 rear) is advantageous for maintaining sensitive lawns and gardens without damaging surfaces. Industrial tire configurations (10-16.5 front; 43x16-20 rear) enhance stability and load-bearing capacity for construction or heavy-duty tasks, albeit at the potential cost of maneuverability in tighter spaces.
