ENGINE DETAIL
The New Holland Workmaster 55 features a turbocharged 4-cylinder diesel engine with a displacement of 2.2L, offering a gross power output of 55hp at 2700 RPM. A dual dry element air cleaner enhances engine efficiency, while its Tier III emissions compliance is suitable for moderate environmental regulations. The high compression ratio of 23.4:1 improves thermal efficiency, but may require high-quality fuel to avoid potential knocking in certain conditions.

NEW HOLLAND WORKMASTER 55 ENGINE
The New Holland Workmaster 55, powered by a 2.2L 4-cylinder diesel engine, provides robust torque ideal for medium-duty farming tasks. With a fuel capacity of 13.5 gallons (51.1 L), it offers a reasonable range for extended operations without frequent refueling, which can enhance productivity. However, farmers should consider the tractor's weight and towing capacities to ensure compatibility with specific implements and terrain types for optimal performance.

TRANSMISSION
The New Holland Workmaster 55 features a synchronized mechanical shuttle with 8 forward and reverse gears, facilitating smooth direction changes without stopping. The 11-inch dry organic clutch enhances durability but requires the operator to stop the tractor to shift gears or ranges, which can hinder productivity in field operations. This setup is ideal for tasks requiring controlled maneuverability but may pose challenges in applications demanding rapid gear changes.

| Description | Four gears in two ranges. Tractor must be stopped to shift gears or range. Synchronized left-hand shuttle. |
MECHANICAL
The New Holland Workmaster 55 tractor features a versatile 4x4 MFWD option, enhancing traction and performance on varied terrains, ideal for both agricultural and light construction tasks. Its mechanical rear differential lock and limited slip front axle provide improved grip, while hydrostatic power steering offers enhanced maneuverability, particularly beneficial in tight spaces. The 8-speed synchronized mechanical shuttle transmission allows for smooth gear changes, enhancing operator efficiency, though it may present a learning curve for those accustomed to fully automatic systems.

NEW HOLLAND WORKMASTER 55 TIRES
The New Holland Workmaster 55 tractor offers versatile tire options, with standard 2WD tires (7.5x16 front and 14.9x28 rear) beneficial for lighter tasks and maneuverability, while the 4WD configuration (9.5x24 front and 14.9x28 rear) enhances traction in challenging conditions, making it suitable for diverse applications like tilling and transporting loads on uneven terrain. However, 2WD may exhibit limitations in traction on slippery surfaces compared to its 4WD counterpart. Choosing the right configuration depends on your operational needs, with 4WD providing better stability and power transfer for demanding tasks.

DIMENSIONS & TIRES
The New Holland Workmaster 55 tractor, weighing between 3,770 and 4,078 pounds, offers a robust yet manageable size for various agricultural tasks. Its tire configuration, with 7.5x16 front and 14.9x28 rear tires, enhances traction and stability, particularly in 2WD applications. This setup is advantageous for light to medium-duty operations on flat terrain but may face challenges in navigating steep gradients or soft ground conditions due to the lack of 4WD.
