ENGINES OVERVIEW
The Oliver 1250 tractor is equipped with either a Fiat 2.3L 4-cylinder diesel engine or a Fiat 1.9L 4-cylinder gasoline engine, providing flexibility in fuel type selection. The diesel variant offers better torque and fuel efficiency, making it advantageous for heavy-duty tasks, while the gasoline engine may be preferred for lighter applications due to lower operational costs. Challenges include potential availability of parts for the diesel engine, depending on market demand and geographic location.

ENGINE DETAIL 1
The Oliver 1250 tractor features a robust Fiat 4-cylinder diesel engine with a displacement of 2.3L, delivering a high compression ratio of 21.5:1 for improved combustion efficiency. Its 24-volt starter system provides reliable ignition, while the oil bath air cleaner enhances engine filtration, potentially extending engine life. However, the relatively limited rated RPM of 2500 may restrict high-speed application capabilities, making it more suitable for low to medium-speed farming tasks such as plowing or tilling.

ENGINE DETAIL 2
The Oliver 1250 tractor features a Fiat 4-cylinder gasoline engine with a relatively low compression ratio of 7.5:1, which might indicate less power output but greater reliability on lower-quality fuels. The oil bath air cleaner enhances filtration efficacy, an advantage for dusty operating environments, while its starter voltage of 24V ensures reliable starting under various conditions. However, with a moderate displacement of 116 ci and a maximum RPM of 2500, it may not be suited for high-speed tasks but excels in applications requiring torque at lower speeds, such as tilling or plowing.

OLIVER 1250 ENGINES
The Oliver 1250 tractor is equipped with two engine options: a Fiat 2.3L 4-cylinder diesel and a Fiat 1.9L 4-cylinder gasoline engine. The diesel variant offers superior fuel efficiency and torque, ideal for heavy-duty applications, whereas the gasoline model provides smoother operation and potentially lower initial costs. Potential challenges include finding parts for older models and varying fuel availability based on the chosen engine type, making suitability dependent on operational needs and local conditions.

TRANSMISSION
The Oliver 1250 tractor features a partially synchronized transmission with 6 forward and 2 reverse gears, allowing for smoother gear shifts particularly between gears 2/3 and 5/6, enhancing operator control during varied terrain applications. The oil capacity of 14 quarts (13.2 liters) is relatively compact, permitting efficient lubrication while still maintaining optimal operating temperatures. This design is advantageous for agricultural operations requiring frequent gear changes, but may pose challenges in high-torque scenarios where full synchronization could reduce wear and improve reliability.

MECHANICAL
The Oliver 1250 tractor features a 4x2 2WD chassis, which provides good maneuverability but may struggle in loose terrain compared to 4WD models. Its mechanical rear differential lock enhances traction during challenging conditions, while the 6-speed partially synchronized transmission offers a balance between speed changes and load handling, albeit with potential challenges in smooth shifting. The open operator station enhances visibility and comfort but may expose the operator to the elements, making it less suitable for prolonged harsh weather conditions.
