ENGINE DETAIL

The White Field Boss 21 tractor features a compact Isuzu 3-cylinder diesel engine, providing 21hp (15.7kW) at 2600 RPM, which is suitable for light agricultural tasks and small-scale farm operations. The high compression ratio of 22.5:1 allows for efficient fuel combustion, while the single-stage air cleaner promotes engine longevity under moderate dust conditions. However, with a maximum idle RPM range of 850-2860, operators must monitor engine performance closely to prevent potential overheating during prolonged low-speed operations.

WHITE FIELD BOSS 21 ENGINE

The White Field Boss 21 is powered by a compact Isuzu 1.2L three-cylinder diesel engine, providing a good balance of torque and fuel efficiency for agricultural tasks. With a 6.1-gallon (23.1-liter) fuel tank, it offers sufficient operational range for small to medium farming activities, though frequent refueling may be necessary for extended use. Potential challenges include limited power output for heavy-duty applications, making it less suitable for larger operations requiring higher horsepower.

TRANSMISSION

The White Field Boss 21 features a robust transmission system with 12 forward and 4 reverse gears, allowing for versatile speed management and fine control in various field conditions. This extensive gear ratio optimization enhances operational efficiency, making it suitable for both heavy-duty tasks and precision farming. However, operators may experience a learning curve with gear shifting, particularly in complex terrains where rapid gear changes are required.

WHITE FIELD BOSS 21 TIRES

The White Field Boss 21 tractor features versatile tire options, allowing adaptation for agricultural tasks (standard ag tires) or turf applications (lawn/turf tires). Its 2WD configurations provide superior traction on flat terrains, while the 4WD options enhance stability and grip on uneven ground. When selecting tires, consider the operational environment: standard ag tires are suitable for heavy tillage, while turf tires minimize soil compaction during landscaping activities.

DIMENSIONS & TIRES

The White Field Boss 21 tractor features a compact 59-inch wheelbase, enhancing maneuverability in tight spaces, making it ideal for small farms and landscaping tasks. Weighing between 1584 to 1672 pounds provides stability; however, the 2WD configuration may limit traction on uneven terrains. The tire combination (4.00-12 front and 12.4-16 rear) ensures decent load-bearing capability, but may require careful consideration for operator demands in varied soil conditions.
