TRANSMISSIONS OVERVIEW
The Fiat-Hesston 100-90 tractor features a 15-speed transmission option, which provides adequate speed versatility for various agricultural tasks, while the 20-speed variant enhances operational efficiency and allows for finer speed adjustments, reducing engine strain during fieldwork. Advantages of the 20-speed system include improved performance in varied terrains and better fuel economy. However, the increased complexity of the 20-speed transmission could raise maintenance challenges, requiring more specialized knowledge and parts availability.
| Description | 15-speed 20-speed |
TRANSMISSION 1
The Fiat-Hesston 100-90 tractor features a 15 forward and 3 reverse gear configuration, offering versatile speed options for varied terrain and tasks such as plowing or transporting materials. This extensive gear range allows for better control during fieldwork, but may require skilled operation to maximize efficiency. Ideal for medium to large-scale farming, it provides the speed needed for extensive work while still allowing for slow precision tasks.
| Gears | 15 forward and 3 reverse |
TRANSMISSION 2
The Fiat-Hesston 100-90 tractor offers a versatile transmission with 20 forward and 4 reverse gears, providing a broad range of speed and torque options for various agricultural tasks. This extensive gear selection can enhance operational efficiency in both fieldwork and transport, allowing for precise control in diverse conditions. However, operators may require some acclimatization to effectively utilize the full potential of the gear setup, especially when shifting between significantly different speeds.
| Gears | 20 forward and 4 reverse |
MECHANICAL
The Fiat-Hesston 100-90 tractor offers versatility in its driveline options, providing both 2WD for improved fuel efficiency on less demanding terrain and 4WD for enhanced traction in challenging conditions. With either a 15-speed or 20-speed transmission, users can achieve optimal performance and speed control across various applications, making it suitable for both field work and transport. However, the increased complexity of a 20-speed transmission may lead to higher maintenance requirements compared to the simpler 15-speed.
