ENGINES OVERVIEW
The Oliver OC-12 tractor offers two engine configurations: a Hercules 5.6L gasoline engine or a Hercules 4.9L diesel engine. The gasoline engine provides higher RPM for faster operations, while the diesel version offers greater torque and fuel efficiency suitable for heavy-duty tasks. When selecting between the two, consider the operational requirements, as the gasoline engine is advantageous for lighter work while the diesel excels in extended, power-demanding applications.

ENGINE DETAIL 1
The Oliver OC-12 features a Hercules JXLD engine, providing a substantial displacement of 339ci (5.6L) with 63hp at a rated RPM of 1750, allowing for good low-end torque suited for heavy-duty applications. With a 6.25:1 compression ratio, it operates efficiently on gasoline, though its lower RPM may limit top speed compared to more modern tractors. Challenges may include maintaining the 6-volt starter system, as it may affect reliability and availability of replacement parts in contemporary setups.

ENGINE DETAIL 2
The Oliver OC-12 features a Hercules DJXC diesel engine with a robust 61.5 hp output, making it suitable for moderate agricultural tasks. With a high compression ratio of 15.5:1, the engine is designed for efficiency, though it may require high-quality diesel fuel to prevent knocking in lower-quality applications. Its liquid-cooled system, with 20-quart coolant capacity, ensures optimal operating temperatures, essential for consistent performance during prolonged use.

OLIVER OC-12 ENGINES
The Oliver OC-12 tractor features a robust Hercules engine option available in both gasoline (5.6L) and diesel (4.9L) variants, providing flexibility in fuel choice depending on operational needs. The 35-gallon fuel tank capacity allows for extended operational hours, reducing refueling frequency, which is advantageous in large-scale agricultural tasks. However, the gasoline engine may offer higher torque at lower RPMs, while the diesel variant typically provides better fuel efficiency and longevity, making it essential to choose based on specific workload scenarios.

TRANSMISSION
The Oliver OC-12 features a [-|-] gear type transmission with 4 forward and 2 reverse speeds, providing versatility for various agricultural tasks such as plowing and hauling. Its oil capacity of 32 quarts (30.3L) ensures proper lubrication and cooling, which is critical for maintaining engine performance during extended operations. An advantage of this setup is the ability to manage heavy loads efficiently, though operators should be mindful of regular maintenance to prevent oil degradation.

OLIVER OC-12 TRANSMISSION
The Oliver OC-12 tractor's 4-speed gear transmission provides versatility in power management, allowing operators to select the optimal speed for different field conditions. Its robust build supports various agricultural tasks but may present challenges in finding replacement parts due to its vintage status. Operators may benefit from steady torque delivery in heavy-duty applications while facing potential limitations in modern speed and efficiency compared to newer designs.
MECHANICAL
The Oliver OC-12 crawler tractor features a robust track drive system, providing enhanced traction and stability on uneven terrain, ideal for agricultural or construction applications. Its open operator station offers improved visibility and operator comfort, but may expose the operator to weather elements and debris. This tractor is suitable for tasks requiring maneuverability in tight spaces while maintaining a balance between power and control.
