ENGINE DETAIL
The AGCO Allis 5680 features a robust 4-cylinder, air-cooled diesel engine with a displacement of 4.0 L and produces 80 hp at 2500 RPM, making it suitable for mid-range agricultural tasks. Its bore-to-stroke ratio (4.13 x 4.55 inches) can enhance torque characteristics for plowing or heavy lifting, but the air-cooled system may limit performance in extremely hot conditions. A 12V starter ensures reliable ignition, but be cautious of battery maintenance in colder climates to ensure optimal starting performance.

TRANSMISSIONS OVERVIEW
The AGCO Allis 5680 tractor features a transmission option of either 12-speed or 16-speed, providing flexibility for varying field conditions and operational needs. The advantage of a 16-speed gearbox is enhanced control over speed and torque, aiding in tasks that require precision, such as tilling or planting. However, more gears can also mean increased complexity in operation and maintenance, which should be considered based on the operator's skill level and intended usage scenario.
| Description | 12-speed/16-speed |
TRANSMISSION 1
The AGCO Allis 5680 tractor features a 12-speed transmission, providing optimal torque management and flexibility in varying field conditions. This allows for precise speed control during plowing or towing operations, enhancing productivity and fuel efficiency. However, the complexity of a multi-speed transmission may require more frequent maintenance checks and operator training to maximize performance.
| Gears | 12 forward and reverse |
TRANSMISSION 2
The AGCO Allis 5680 tractor features a 16-speed transmission, providing flexibility in various agricultural tasks by allowing precise speed and power adjustments for a wide range of implements. This extensive gear selection enhances operational efficiency, making it suitable for both fieldwork and transport scenarios. However, mastering gear selection may require some operator training to fully leverage the tractor's capabilities.
| Gears | 16 forward and reverse |
MECHANICAL
The AGCO Allis 5680 tractor offers flexible drivetrain options with both 2WD and 4WD configurations, allowing adaptability to various terrains and handling requirements. The optional ROPS cab provides enhanced operator safety, while the choice between 12-speed and 16-speed transmissions enables precise speed control for diverse field operations. However, the absence of a fully enclosed cab may limit comfort in adverse weather conditions, making it less ideal for prolonged use in harsh climates.

AGCO ALLIS 5680 TIRES
The AGCO Allis 5680 tractor features a robust tire configuration with agricultural front tires (7.50-18) and larger rear tires (16.9R34), providing enhanced traction and stability for field operations. Its rear tire size suggests compatibility for heavier implements, making it ideal for plowing and tillage tasks. However, the smaller front tire may require attention in terms of steering precision and load distribution when handling larger rear-mounted equipment.

DIMENSIONS & TIRES
The AGCO Allis 5680, with a wheelbase of 92.9 inches, offers enhanced stability and maneuverability, ideal for tight agricultural operations. Its weight of 6000 lbs provides a solid foundation for traction, while the tire configuration (front tire 7.50-18 and rear tire 16.9R34) balances load distribution and ground contact for improved performance in varied terrains. However, the relatively limited wheelbase may pose challenges in heavy-duty plowing, potentially requiring additional ballast for optimal performance in more demanding applications.
