Introduction
Fiat 665C Crawler Tractor
The Fiat 665C is an agricultural crawler tractor produced between 1982 and 1984. Designed for demanding field operations, this tracked machine belongs to the Fiat crawler series, emphasizing stability and traction in challenging terrain conditions.
Engine and Performance
The tractor is powered by the Fiat 8045.2, a 3.5-liter, 4-cylinder diesel engine. This liquid-cooled power unit features direct injection and a Thermostart pre-heating system, delivering 66 hp (49.2 kW). It is designed to maintain consistent output at a rated engine speed of 2500 RPM.
Transmission and Drive
The 665C utilizes a crawler drive system featuring 12.2-inch tracks for optimal ground pressure distribution. The mechanical transmission offers multiple configurations, including a base 8-speed forward and 4-speed reverse gear set, complemented by a 279.4mm dry disc clutch. Final drives are managed through spur gears, and braking is handled by band brakes.
Hydraulics and PTO
The hydraulic system is of the open-center type, providing a pump flow of 9 gpm (34.1 lpm) at a pressure of 2460 psi. It supports up to three rear valves for implement operation. The rear PTO is independent, providing a standard 540 RPM at an engine speed of 2197 RPM, allowing for versatile implement integration.
Hitch and Ergonomics
The tractor is equipped with a Category II rear hitch featuring both position and draft control for precise implement management. Operator safety is provided by a two-post Roll-Over Protective Structure (ROPS) fitted with a canopy.
Conclusion
With a weight ranging from 7529 to 7859 pounds, the Fiat 665C is a specialized machine suited for farmers requiring high traction and stability on uneven or soft ground. Its combination of a reliable diesel engine and robust crawler undercarriage makes it a capable performer for primary cultivation and heavy-duty field tasks.
