Introduction
Fiat 45-76 Orchard and Vineyard Tractor
The Fiat 45-76 is a specialized agricultural tractor produced between 1990 and 1992 as part of the 55-76 series. Designed primarily for orchard and vineyard operations, this machine offers a compact footprint and reliable performance for specialized cultivation tasks.
Engine and Performance
The tractor is powered by the Fiat 8035.06, a 2.7-liter, 3-cylinder liquid-cooled diesel engine. It generates a rated power of 44 hp (33.1 kW) at 2500 engine RPM. The engine features a 17:1 compression ratio and uses a dry-type air cleaner to ensure longevity in dusty field conditions.
Transmission and Drivetrain
Multiple transmission configurations were available, including a 12-speed partially synchronized gearbox or a 12-speed mechanical shuttle for frequent direction changes. An optional creeper range expands the configuration to 20 forward and 8 reverse gears. All versions utilize a 254mm dry disc clutch and include a mechanical rear differential lock to improve traction.
Hydraulics and PTO
The 45-76 is equipped with an open-center hydraulic system providing a pump flow of 8.7 gpm (32.9 lpm) at a system pressure of 2697 psi (186 bar). The independent rear PTO offers standard speeds of 540 RPM at 2200 engine RPM, with an optional 540/1000 RPM configuration to accommodate a wide array of implements.
Mechanical and Dimensions
Available in both two-wheel and four-wheel drive configurations, the tractor features power steering and wet disc brakes for enhanced control. The Category I rear hitch incorporates both position and lower-link draft control. The machine is designed with a narrow tread width, fitting its intended use in restricted orchard rows.
Conclusion
The Fiat 45-76 is a robust, purpose-built tractor tailored for high-value crop environments. Its combination of mechanical simplicity, varied transmission options, and compact dimensions makes it a reliable asset for vineyard and orchard management.
