ENGINE DETAIL
The Hesston 680 tractor is powered by a Fiat 8045 diesel engine with a displacement of 3.5L, offering direct injection for improved fuel efficiency and performance. With a 17:1 compression ratio and a rated RPM of 2500, it provides a robust power delivery suitable for both fieldwork and heavy-duty tasks. However, its relatively low RPM may limit its speed capabilities in transport scenarios, emphasizing its design for torque rather than high-speed operations.

TRANSMISSIONS OVERVIEW
The Hesston 680 tractor is equipped with an 8-speed partially synchronized transmission and a mechanical shuttle, offering flexibility in speed control and direction changes. The 16-speed capability enhances versatility across various tasks, making it suitable for both fieldwork and transport scenarios. A potential challenge might be the learning curve associated with the partially synchronized shifting, which could require operator training for optimal performance.

TRANSMISSION 1
The Hesston 680 tractor features a partially synchronized transmission with eight forward and two reverse gears, enabling efficient operation across varied terrains. The synchronization in gears 3 and 4 enhances shifting smoothness, particularly beneficial for applications requiring frequent gear changes, such as tilling or plowing. However, the partially synchronized design may pose challenges during quick directional changes, necessitating operator skill for optimal performance.

MECHANICAL
The Hesston 680 tractor features a 4x2 2WD and 4x4 MFWD option, providing versatility for varied terrains; however, the 2WD might limit performance in challenging conditions. Its hydrostatic power steering enhances maneuverability, especially in tight spaces, while the differential hydraulic disc brakes ensure reliable stopping power. The optional Supercomfort cab with air conditioning creates a conducive operator environment for extended use, making it suitable for prolonged agricultural tasks.

HESSTON 680 TIRES
The Hesston 680 tractor features a versatile tire configuration with 7.50-16 (2WD) or 11.2-24 (4WD) front tires and 16.9-30 rear tires, optimizing traction and stability across various terrains. This dual-wheel setup enhances load-bearing capabilities, making it suitable for agricultural tasks like plowing and tilling, particularly in wetter or uneven ground conditions. However, the 2WD limitation may pose challenges in extreme conditions, where 4WD would provide better mobility and reduced tire slippage.

DIMENSIONS & TIRES
The Hesston 680 tractor features a relatively short wheelbase of 89 inches (226 cm), which can enhance maneuverability in tight spaces, making it advantageous for smaller farms or specialized tasks. Weighing between 5407 and 6029 pounds, it offers a decent balance of stability and power, especially with the larger rear tires (16.9-30), which provide improved traction on various terrains. However, the limited tire size on the front (7.50-16) may pose challenges in heavy-duty applications or uneven ground, potentially leading to increased wear or reduced performance in harsh conditions.
