ENGINE DETAIL
The Cletrac DG tractor features a Hercules RXC gasoline engine with a significant displacement of 529 ci (8.7L) and a low compression ratio of 5.8:1, making it suitable for heavy-duty tasks but potentially less efficient in fuel usage. Its oil bath air cleaner helps maintain engine performance in dusty conditions, while the 1300 RPM rating offers ample torque for agricultural applications. However, with a coolant capacity of 41 quarts (38.8L), proper maintenance is critical to prevent overheating during extended use.

CLETRAC DG ENGINE
The Cletrac DG tractor is powered by a Hercules 8.7L 6-cylinder gasoline engine, providing robust performance for various agricultural applications. Its 30-gallon (113.6L) fuel tank offers extended operating hours before refueling, making it efficient for long-duration tasks. However, the reliance on gasoline may be a drawback in areas where diesel fuel is preferred for economy and fuel availability.

TRANSMISSION
The Cletrac DG tractor features a [-|-] gear type transmission with 4 forward and 2 reverse gears, facilitating adequate speed and maneuverability for various field operations. The dry disc clutch provides reliable engagement but may require more maintenance compared to wet clutches in terms of wear and heat management. This setup is ideal for agricultural tasks that require frequent direction changes, although operators should be mindful of clutch performance under heavy loads.

MECHANICAL
The Cletrac DG, with its crawler chassis, offers enhanced traction on uneven terrain, making it suitable for agricultural and construction applications. The open operator station provides visibility and accessibility but may expose the operator to environmental elements. The 4-speed gear transmission allows for versatility in speed and torque, but users should be cautious about navigating steep gradients to avoid stalling.
