TRANSMISSION
The Leyland 255 tractor's mechanical dry disc clutch provides reliable engagement, crucial for managing the power delivery during operation. With a total of 10 forward and 2 reverse gears, this configuration allows for versatile speed and torque options, enhancing productivity across varied tasks. However, the limited number of ranges may challenge operators in extreme conditions requiring more precise gear selection.

MECHANICAL
The Leyland 255 tractor features a 4x2 2WD chassis, which offers simplicity and lower maintenance costs but may limit off-road capabilities compared to 4WD models. The power-assisted steering enhances maneuverability, while the mechanical dry disc brakes provide reliable stopping power, albeit with potentially increased wear in wet conditions. The 10-speed gear transmission allows for versatile speed selection, making it suitable for a range of agricultural tasks; however, the open operator station may expose the operator to weather elements unless the optional cab is utilized.
