TRANSMISSIONS OVERVIEW
The AGCO ST25 tractor is equipped with a 6-speed gear/hydrostatic transmission, offering versatility in speed management and enhanced control in varying terrain conditions. This combination allows for efficient power delivery during tasks such as tilling or hauling, while also providing smoother operation in tight spaces. However, potential challenges may include a steeper learning curve for new operators and increased maintenance requirements related to the hydrostatic system.

TRANSMISSION 1
The AGCO ST25 features a 6-speed forward and 2-speed reverse transmission, offering a versatile range for various agricultural tasks, facilitating both speed and torque adjustments. Its dry disc clutch enhances durability and reduces maintenance needs, but it may require careful operation to prevent overheating during prolonged use. Ideal for small to medium farming operations, the tractor’s gear setup allows for efficient maneuverability and responsiveness in diverse field conditions.
| Type | gear |
| Gears | 6 forward and 2 reverse |
| Clutch | dry disc |
TRANSMISSION 2
The AGCO ST25 features a hydrostatic transmission, providing infinite speed selection within two ranges for enhanced maneuverability and precision during operation. This design allows for smooth operation and reduced operator fatigue, making it suitable for tasks like mowing or light tillage. However, the hydrostatic system may face challenges in terms of durability and efficiency compared to traditional gear-driven systems, particularly in heavy-duty applications.
