ENGINE DETAIL

The Fiat 446 tractor features a robust 3-cylinder, 2.6L diesel engine with a direct injection fuel system, delivering 50hp at 2600 RPM, making it suitable for varied agricultural tasks. With a high compression ratio of 17:1, this engine provides efficient fuel usage but may require higher quality diesel to prevent knocking. Challenging aspects include its relatively limited oil capacity of 7.9 quarts, which necessitates regular maintenance checks to ensure optimal engine lubrication and longevity.

FIAT 446 ENGINE

The Fiat 446 is powered by a 2.6L 3-cylinder diesel engine, which delivers a balance of torque and fuel efficiency, suitable for light to moderate agricultural tasks. With a fuel tank capacity of 16.1 gallons (60.9L), it provides ample operational range, although the relatively small size may necessitate more frequent refueling during extensive work sessions. This tractor is advantageous for small to medium-sized fields, but its limited horsepower could pose challenges for heavy-duty applications.

TRANSMISSIONS OVERVIEW

The Fiat 446 tractor’s 8-speed or 12-speed gearbox options provide versatility in varying field conditions, allowing for effective power management and speed control. The 12-speed variant enhances operational efficiency, especially during tasks requiring precision, like plowing or tilling. However, the complexity of the 12-speed gearbox may present maintenance challenges compared to the simpler 8-speed system, so choosing the right option depends on the intended use and operator familiarity.

TRANSMISSION 1

The Fiat 446 tractor features an 8-speed forward and 2-speed reverse gear system, allowing for versatile speed control and improved maneuverability in various field conditions. Its 279.4mm dry disc clutch provides robust engagement and effective power transfer, but may present challenges in terms of heat dissipation during prolonged operation. This tractor is well-suited for medium-duty agricultural tasks, benefiting from its adaptability and performance efficiency.

TRANSMISSION 2

The Fiat 446 features a 12-forward and 3-reverse gear configuration, providing versatile speed options for various agricultural tasks. The 279.4mm dry disc clutch ensures reliable power transmission but may require more frequent maintenance compared to hydraulic options. In scenarios demanding sudden torque changes, users may find the dry clutch challenging as it can lead to increased wear and potential slippage under heavy loads.

FIAT 446 TIRES

The Fiat 446 tractor features a 2WD configuration with standard agricultural tires, providing decent traction for light to moderate field operations. The front tire size of 6.00-16 and varying rear sizes (12.4/11-32 and 12.4/11-32 or 8.3/8-24) allows flexibility in terms of load distribution and stability on uneven terrain. However, the 2WD setup may limit performance in more challenging conditions, such as wet or hilly landscapes, where four-wheel drive could offer better grip and maneuverability.

DIMENSIONS & TIRES

The Fiat 446 tractor's 2WD configuration, with a wheelbase of 80.7 inches, provides enhanced stability for hauling and general field work, while the lighter 4WD option at 79.2 inches improves maneuverability in tighter spaces. Weighing between 4299 to 4762 pounds, this tractor is well-balanced, but might struggle with traction in muddy conditions without four-wheel drive. The choice between 2WD and 4WD should be based on the terrain and specific tasks—2WD for flat and dry surfaces, and 4WD for uneven or wet conditions.
