ENGINE DETAIL

The Kubota STW37, equipped with a D1803 diesel engine, offers a compact 1.8L displacement that results in an efficient power output of 34.7hp (25.9kW) at a rated 2700 RPM, making it suitable for light agricultural tasks or landscaping. Its 3-cylinder configuration ensures a good balance between torque and fuel efficiency, while the electric starter simplifies operation. However, the limited horsepower may pose challenges for heavier applications, making it ideal for tasks that do not require high power levels.

KUBOTA STW37 ENGINE

The Kubota STW37 features a robust 1.8L 3-cylinder diesel engine, providing a blend of power and fuel efficiency for small to medium agricultural tasks. With a fuel tank capacity of 7.8 gallons (29.5 liters), it allows for extended operation between refuels, making it suitable for longer tasks or larger plots of land. However, while the smaller engine size is advantageous for maneuverability, it may present challenges in high-demand applications requiring more horsepower.

TRANSMISSION

The Kubota STW37 features a hydrostatic transmission, providing seamless control over speed and direction, which enhances ease of operation in various field conditions. With its infinite gears across three ranges for forward and reverse, operators can precisely match the tractor's performance to specific tasks, such as tilling or hauling. However, the complexity of hydrostatic systems may require more maintenance and can be less efficient in terms of fuel consumption compared to traditional gear-driven transmissions.

Gears infinite (3-range) forward and reverse

MECHANICAL

The Kubota STW37 features a 4x4 MFWD chassis, enhancing traction and stability in diverse terrains, while the mechanical rear differential lock further improves traction on slippery surfaces. Its power steering and wet disc brakes provide ease of control and safety during operation, making it suitable for demanding agricultural tasks. The optional air-conditioned cab offers comfort during extended use, but the absence of a fully enclosed cab can expose the operator to adverse weather conditions.

KUBOTA STW37 TIRES

The Kubota STW37 is equipped with standard agricultural tires (6.00-12 front, 9.5-22 rear) that provide good traction and stability in field conditions, ideal for tillage and cultivation tasks. The optional lawn/turf tires (24x8.50-14 front, 13.6-16 rear) offer a more gentle footprint, minimizing soil compaction and protecting grassed areas during landscaping tasks. When selecting between tire types, consider the primary use: agricultural applications favor standard tires, while turf-focused tasks benefit from the lower impact of lawn/turf configurations.
