ENGINE DETAIL

The Kubota L4400 features a robust 2.2L, 4-cylinder diesel engine producing 45.3 hp at 2600 RPM, ensuring sufficient power for a variety of agricultural tasks. With an oil capacity of 8 quarts, the tractor allows for extended service intervals, while the 6.9-quart coolant capacity aids in maintaining optimal operating temperatures, crucial for demanding applications. However, the fixed displacement may limit performance in high-altitude operations, and users should consider proper maintenance to avoid overheating issues during extended use.

KUBOTA L4400 ENGINE

The Kubota L4400 features a robust 2.2L 4-cylinder diesel engine, providing a balance of power and fuel efficiency suited for agricultural tasks. Its compact design allows for versatile maneuverability in tight spaces, but the engine's size can limit peak horsepower compared to larger models. Ideal for small to medium farms, the L4400 excels in tasks like tilling, mowing, and loader operations, but may face challenges with heavy-duty implements or steep terrain.

TRANSMISSIONS OVERVIEW

The Kubota L4400 features a hydrostatic transmission providing seamless speed control, ideal for varying field conditions and operator comfort. Its 8-speed constant mesh ensures reliable power delivery with reduced gear shift stress, enhancing durability. However, the hydrostatic system may lead to slightly lower fuel efficiency under heavy loads compared to traditional transmissions.

TRANSMISSION 1

The Kubota L4400's hydrostatic transmission offers smooth operation with infinite speed control across three ranges, enhancing maneuverability during tasks. Its oil capacity of 47.5 quarts (45.0 liters) ensures adequate lubrication for extended use, but regular maintenance is crucial to avoid overheating issues. When considering this model, note that while hydrostatic systems provide ease of use, they may be less efficient under heavy load compared to traditional gear transmissions.

Type hydrostatic
Gears infinite (3-range) forward and reverse
Oil capacity 47.5qts / 45.0L
Description Originally only available with a gear transmission, the hydrostatic was made an option on the L4400 in 2006.

TRANSMISSION 2

The Kubota L4400 features a constant mesh transmission with 8 forward and 4 reverse gears, providing versatile speed options suitable for varied agricultural tasks. The mechanical shuttle shifting enhances ease of operation, allowing quick transitions between forward and reverse—ideal for loader work or frequent directional changes. However, the oil capacity of 42.4 quarts necessitates regular maintenance to ensure optimal performance and longevity of the drivetrain.

Type constant mesh
Gears 8 forward and 4 reverse
Oil capacity 42.4qts / 40.1L
Description Four gears (1-4) in two ranges (Low/High) and reverse (R). Mechanical shuttle shifting between forward-low and reverse.

MECHANICAL

The Kubota L4400 tractor features a 4x4 MFWD option, enhancing traction for varied terrains, but limited to a rear differential lock that may affect maneuverability in tight spaces. Its hydrostatic 8-speed transmission provides smooth, efficient power delivery, ideal for applications requiring frequent speed adjustments. The foldable two-post ROPS offers safety without compromising visibility, though options for full cab protection may be limited.
