Introduction
Leyland 455 Utility Tractor
The Leyland 455 is a utility tractor produced between 1978 and 1988. It originated as a variant of the Leyland 255 model, featuring a four-wheel drive system integrated by Four Wheel Traction Ltd to enhance traction and versatility in agricultural operations.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled engine with a displacement of 222 cubic inches (3.6 liters). It operates at a rated speed of 2200 RPM and features a compression ratio of 17.8:1. The engine intake is equipped with a dry-type air cleaner to ensure consistent performance in dusty field conditions.
Transmission and Drivetrain
Equipped with a mechanical dry disc clutch, the transmission system offers 10 forward and 2 reverse gears. The gear configuration consists of five speeds across two ranges (low and high), providing the necessary flexibility for various field tasks. The machine is configured with a four-wheel drive system for improved stability and force distribution.
Hydraulics and PTO
The tractor utilizes an open-center hydraulic system with a pump flow rate of 7.9 gallons per minute (29.9 liters per minute). The rear power take-off (PTO) is independent and operates at a standard 540 RPM. The rear hitch is compatible with Category II/I implements and includes both position and draft control for precise implement management.
Controls and Braking
Operator control is facilitated by a power-assisted steering system, reducing steering effort during maneuvers. Braking is managed by mechanical dry disc brakes, providing reliable stopping power for the utility tractor.
Conclusion
The Leyland 455 serves as a robust utility tractor suited for general agricultural tasks. Its combination of four-wheel drive, independent PTO, and draft-controlled hitch makes it a functional choice for farmers requiring consistent performance and mechanical reliability.
