ENGINE DETAIL

The Fiat-Hesston 55-56 features a 2.7L Fiat 8035.06 diesel engine with a direct injection system, providing efficient combustion and enhancing power output of 55 hp at 2500 RPM. The engine's compression ratio of 17:1 contributes to better torque generation, making it suitable for various agricultural applications. However, the relatively small displacement paired with a 3-cylinder layout may lead to lower torque compared to larger alternatives, potentially impacting performance during heavy-load operations.

HESSTON 55-56 ENGINE

The Fiat-Hesston 55-56 tractor is equipped with a robust 2.7L 3-cylinder diesel engine, known for its efficient fuel consumption and durability under load. With a fuel tank capacity of 19.2 gallons (72.7 L), it enables extended operation, making it suitable for medium-sized agricultural tasks without frequent refueling. However, operators should consider that the relatively smaller engine size may limit power output for heavier implements, potentially requiring careful management of load capabilities.

TRANSMISSIONS OVERVIEW

The Fiat-Hesston 55-56 tractor features an 8-speed or 12-speed partially synchronized transmission, allowing for smooth gear transitions suitable for various agricultural tasks. The partially synchronized design enables easier shifting between gears without clutch engagement, beneficial during field operations. However, operators may still experience some difficulty in extreme speed changes, making it less ideal for high-speed road travel compared to fully synchronized systems.

Description 8-speed partially synchronized/12-speed partially synchronized

TRANSMISSION 1

The Fiat-Hesston 55-56 tractor features a partially synchronized transmission with a total of 8 forward and 2 reverse gears, organized into four gears in each of the two ranges. This design enhances operational flexibility for various tasks, but may present challenges in achieving seamless gear shifts under heavy loads. Ideal for farm applications requiring a balance of speed and torque, it is crucial for operators to be familiar with the gear engagement process to maximize efficiency.

Type partially synchronized
Gears 8 forward and 2 reverse
Description Four gears (1-4), plus reverse (R), in two ranges (I/II)

TRANSMISSION 2

The Fiat-Hesston 55-56 tractor features a partially synchronized transmission with a total of 12 forward and 3 reverse speeds, allowing for versatility in various agricultural tasks. The transmission's design offers four direct gears across three range settings, which enhances the operator's ability to manage different load conditions efficiently. However, the partially synchronized system may present challenges in smooth gear shifting, particularly under load, necessitating operator experience for optimal performance.

Type partially synchronized
Gears 12 forward and 3 reverse
Description Four gears (1-4), plus reverse (R), in three ranges (I, II, and III).

MECHANICAL

The Fiat-Hesston 55-56 tractor features a robust 4x2 configuration with options for 2WD or 4WD, enhancing versatility for different terrain conditions. Its ROPS cab provides essential safety for the operator, while the 8-speed or 12-speed partially synchronized transmissions offer good maneuverability and control during various agricultural tasks. A potential challenge may be the limited synchronization at higher speeds, which could affect shifting in more demanding applications.

HESSTON 55-56 TIRES

The Fiat-Hesston 55-56 tractor offers versatile configurations with both 2WD and 4WD options, enhancing traction for varied agricultural applications. The 2WD setup is best suited for flat terrains with standard agricultural tires, while the 4WD configuration with larger front tires improves stability and maneuverability on uneven surfaces. Considerations include the operational costs associated with 4WD maintenance versus the simplicity and fuel efficiency of the 2WD system.

2WD Standard tires (ag) Front: 6.00-16. Rear: 12.4-32
4WD Standard tires (ag) Front: 11.2-20. Rear: 12.4-32
