ENGINE DETAIL
The Oliver 1255 tractor features a robust Fiat 8035 diesel engine, offering a balanced displacement of 2.3L and a notable compression ratio of 17:1, providing efficient fuel combustion. With its direct injection fuel system and oil bath air cleaner, the tractor is designed for reliability and longevity, though maintenance may be intensive due to the air filter type. The 2400 RPM rated speed allows for effective power delivery; however, operators should ensure proper oil and coolant capacities (8.25qts and 13.5qts respectively) for optimal operation and cooling efficiency during extended use.

OLIVER 1255 ENGINE
The Oliver 1255 is powered by a Fiat 2.3L 3-cylinder diesel engine, offering a balance of fuel efficiency and adequate torque for medium-duty agricultural tasks. Its three-cylinder configuration may provide lower initial weight, enhancing maneuverability, but could lead to vibrations compared to larger engines. Expect challenges in parts availability due to its specific engine design, particularly in regions where Fiat components are less common.

OLIVER 1255 TIRES
The Oliver 1255 tractor offers two-wheel drive and four-wheel drive configurations, allowing versatility for various agricultural tasks. The 2WD system with narrower tires (6.00-16) provides better maneuverability on smaller farms, while the 4WD option with wider tires (16.9-30) enhances traction and stability on uneven terrain. Keep in mind that 2WD may be less efficient in wet conditions, making 4WD preferable for heavier-duty applications or when operating on softer ground.
