ENGINE DETAIL

The Hesston 80-90 tractor, equipped with a Fiat 8045.05 diesel engine, offers a robust 80hp power output at a rated RPM of 2500, making it suitable for medium-duty agricultural tasks. Its direct fuel injection and ether pre-heating system enhance cold-start performance, though the 17:1 compression ratio necessitates high-quality diesel to avoid knocking. The compact 3.9L displacement provides a balance of torque and efficiency, ideal for farming scenarios that require reliability in varied conditions.

HESSTON 80-90 ENGINE

The Hesston 80-90 tractor is powered by a Fiat 3.9L 4-cylinder diesel engine, providing a balance of power and fuel efficiency. With a 21.1-gallon (79.9L) fuel tank, it offers extended operating time, making it suitable for medium to large agricultural tasks without frequent refueling. However, engine maintenance may require specialized knowledge due to its less common diesel configuration; hence, access to parts and service could be a challenge in some regions.

TRANSMISSIONS OVERVIEW

The Hesston 80-90 tractor features a 12-speed synchromesh transmission which provides smooth gear engagement, enhancing operator comfort and efficiency in varying field conditions. The mechanical shuttle allows for quick direction changes without clutch disengagement, ideal for applications requiring frequent forward and reverse movement. Additionally, the 20-speed creeper gear enables precise low-speed control, beneficial for tasks like tillage or planting, but may present a learning curve for less experienced operators.

TRANSMISSION 1

The Hesston 80-90 tractor features a synchromesh transmission with 12 forward and 4 reverse gears, providing versatile speed and torque management for various agricultural tasks. The 279.4mm dry disc clutch ensures reliable engagement while minimizing slippage, critical for heavy-duty operations. With its three-range system (I-III) and four selectable gears, operators can efficiently navigate different terrains and load demands, though mastering the gear transitions may present a learning curve for inexperienced users.

Type synchromesh
Gears 12 forward and 4 reverse
Clutch 279.4mm dry disc
Description Four gears (1-4) in three ranges (I-III) plus reverse range.

TRANSMISSION 2

The Hesston 80-90 tractor features a mechanical shuttle transmission, allowing for seamless direction changes without clutching, enhancing operational efficiency during field tasks. With 12 forward and reverse gears, it offers versatile speed options for varying terrains and applications, improving maneuverability. However, mechanical shuttles may require more operator skill to manage effectively compared to hydrostatic systems, posing a learning curve for new users.

Description With 18.4-30 rear tires

TRANSMISSION 3

The Hesston 80-90 tractor's creeper gear type allows for exceptional low-speed maneuverability, ideal for precision tasks such as tilling or planting. With 20 forward and 8 reverse gears, it provides versatility in various agricultural operations, enabling operators to select appropriate speeds for different implements. However, the complexity of having multiple gears may require more operator training to optimize performance.

Gears 20 forward and 8 reverse

MECHANICAL

The Hesston 80-90 features a robust 4x2 2WD or optional 4x4 MFWD configuration, providing versatility for various terrain challenges. The planetary final drives and mechanical rear differential lock enhance traction and stability, making it suitable for demanding agricultural tasks. While the 12-speed transmissions allow for fine-tuning power delivery, the optional creeper gear offers exceptional low-end control for tasks like tilling or planting.

HESSTON 80-90 TIRES

The Hesston 80-90 tractor's 2WD configuration is suited for less demanding agricultural tasks on flatter terrains while the 4WD variant enhances traction in challenging conditions, making it ideal for uneven or muddy fields. The choice of front tire sizes—9.5L-15 for 2WD and 13.6-24 for 4WD—improves stability and maneuverability, primarily when working with larger implements. However, the 13.6-38/16.9-34 rear tire options may increase rolling resistance and fuel consumption, so careful consideration of the application is necessary for optimal performance.
