KUBOTA GT-21 POWER
ENGINE DETAIL
The Kubota GT-21 tractor features a robust D1403 diesel engine known for its reliable performance and fuel efficiency, making it ideal for small agricultural tasks and light-duty applications. With a displacement of 1.4L and rated power of 20.7hp at 2600 RPM, it balances adequate power output with a compact size, promoting maneuverability in tight spaces. A notable advantage of the 12V electric starter is ease of use, although users should be mindful of the maintenance needs associated with liquid-cooled systems, particularly in extreme temperatures.

KUBOTA GT-21 ENGINE
The Kubota GT-21 is powered by a 1.4L 3-cylinder diesel engine, providing efficient fuel consumption and robust torque for various applications. With a 7.4-gallon (28.0L) fuel tank, it offers extended operational capability, minimizing refueling downtime. However, the compact engine may limit power in heavy-duty tasks, making it more suited for moderate agricultural or landscaping work rather than intensive field operations.

TRANSMISSIONS OVERVIEW
The Kubota GT-21 features a 12-speed hydrostatic transmission, allowing for seamless speed adjustments and precise control in various agricultural applications. This design enhances operator comfort and reduces fatigue during prolonged use, but may require regular maintenance to ensure optimal performance. Ideal for tasks such as mowing or light tillage, the hydrostatic system provides excellent adaptability in diverse terrain conditions.

TRANSMISSION 1
The Kubota GT-21 tractor features a 12 forward and 4 reverse gear configuration within four distinct ranges, including a creeper range for ultra-low speed operations. This gearbox design allows for versatile maneuverability and precise control, particularly beneficial in tasks requiring slow speed, such as tilling or landscaping. However, the complexity of the multi-range system may pose a learning curve for operators unfamiliar with advanced transmission setups.

TRANSMISSION 2
The Kubota GT-21 features a hydrostatic transmission, providing seamless speed adjustments without gear shifting—ideal for tasks requiring precision like mowing or tilling. Its infinite (3-range) forward and reverse gears enhance maneuverability, making it suitable for diverse agricultural tasks or tight spaces. However, hydrostatic systems can demand more maintenance compared to traditional gear systems, potentially increasing long-term ownership costs.

MECHANICAL
The Kubota GT-21 features a 4x4 MFWD (Mechanical Front-Wheel Drive) system, enhancing traction and stability on varied terrains, making it ideal for both agricultural and landscaping tasks. With a two-post folding ROPS (Roll Over Protective Structure), safety is prioritized while maintaining a compact profile for maneuverability. Its 12-speed hydrostatic transmission offers smooth operation and precise speed control, benefiting applications that require varied power delivery and consistent performance.

KUBOTA GT-21 TIRES
The Kubota GT-21 tractor features standard agricultural tires with front dimensions of 6-14 and rear dimensions of 8.3-24, providing a balance of traction and stability for varied terrain. The optional GT-21J tires, with a rear size of 9.5-22, enhance flotation and reduce soil compaction, making them advantageous for softer ground conditions. However, the larger rear tires may affect maneuverability in tighter spaces, which is a consideration in small-scale farming scenarios.
