ENGINE DETAIL
The White Field Boss 31 features a robust Isuzu 3-cylinder diesel engine, offering 30hp at a rated RPM of 2600, making it suitable for moderate agricultural tasks and light-duty operations. With a notable compression ratio of 21.4:1, it balances power output with fuel efficiency, although the limited displacement (1.5L) may restrict performance under heavy load scenarios. The starter system operates on a 12V system, ensuring reliable ignition, but potential challenges may arise in cold-start conditions without proper maintenance.

TRANSMISSION
The White Field Boss 31 features a partially synchronized triple-sync transmission, allowing for smooth gear shifts between its 12 forward and 4 reverse gears. The configuration of three synchronized gears within four ranges provides versatility for various field applications, facilitating efficient power delivery and speed adjustment. However, operators should be cautious when shifting under load to avoid potential gear grinding during transitions.

MECHANICAL
The White Field Boss 31 offers a versatile 4x2 or 4x4 configuration, allowing for improved traction in varying conditions, particularly advantageous in muddy or uneven terrains with the optional MFWD. The 12-speed partially synchronized transmission enhances operation efficiency, though it may require driver familiarity for optimal performance. The manual steering in 2WD can present challenges in maneuverability, while the mechanical wet disc brakes provide consistent stopping power, essential for safety in heavy-duty applications.

WHITE FIELD BOSS 31 TIRES
The White Field Boss 31 offers versatile tire options, accommodating both agricultural and lawn/turf applications with standard sizes tailored for 2WD and 4WD configurations. The 2WD setup utilizes narrower front tires, enhancing maneuverability in tight spaces, while the 4WD variant's wider front tires provide improved traction in challenging terrains. However, the choice of tires significantly impacts operational efficiency; agricultural tires excel in soil handling, while turf tires minimize ground disturbance, making the tractor adaptable across different farming scenarios.

DIMENSIONS & TIRES
The White Field Boss 31 tractor's 65-inch wheelbase offers enhanced stability for various agricultural tasks, but the relatively lightweight range of 2215 to 2414 pounds may limit its ability to handle heavier loads on uneven terrain. The 5.00-15 front tires and 11.2-24 rear tires indicate a good balance of traction and maneuverability, though the two-wheel drive (2WD) configuration may challenge performance in muddy or steep conditions. Ideal for small to medium-sized farms, the Field Boss 31 excels in lighter operational tasks, but operators should be cautious of its limitations in very demanding environments.
