TRANSMISSIONS OVERVIEW

The Fiat 90-90 tractor features a robust 15-speed synchronized transmission complemented by a 20-speed creeper option, enhancing versatility for various agricultural tasks. The synchronized gears allow smooth shifting, critical for maintaining engine power during load changes, while the creeper speeds are advantageous for precision work such as plowing or cultivating in tight spaces. However, the complexity of a 15-speed system may present a learning curve for some operators, necessitating familiarization for optimal performance.

TRANSMISSION 1

The Fiat 90-90 tractor features a synchronized transmission with 15 forward gears and 3 reverse gears, allowing for versatile speed and torque management. The dry disc clutch provides reliable engagement, though it may require more frequent maintenance compared to wet clutches. For optimal performance in diverse field conditions, the optional 40 KPH gearbox and four-wheel-drive system enhance traction and speed adaptability.

Gears 15 forward and 3 reverse
Clutch dry disc
Description Five gears, plus reverse, in three ranges. A 40 KPH gearbox was available with four-wheel drive.

TRANSMISSION 2

The Fiat 90-90 tractor features a creeper transmission with a total of 20 forward and 4 reverse gears, allowing for exceptional low-speed control, which is advantageous for tasks like plowing or precision farming. The dry disc clutch provides reliable engagement, although it may require more frequent maintenance than oil-immersed clutches, especially in heavy-duty applications. Ideal for both field and transport work, this tractor's gear ratio variety can optimize performance across diverse agricultural needs.

MECHANICAL

The Fiat 90-90 tractor offers a 4x2 or optional 4WD configuration, providing versatility for various field conditions; however, the absence of a front differential lock could limit traction in challenging terrains. Its hydraulic wet disc brakes enhance stopping power and durability, crucial for heavy-duty operations, and the availability of hydraulic trailer brakes increases towing safety. The 15-speed synchronized transmission, with an optional 20-speed creeper mode, allows for precise speed adjustments, making it ideal for tasks requiring high maneuverability, such as plowing or seedbed preparation.
