ENGINE DETAIL
The Cletrac AG tractor features a robust Herclues gasoline engine with a 3.7 L displacement, advantageous for agricultural applications due to its liquid cooling and efficient 4-cylinder design. Operating at a rated RPM of 1400, it delivers reliable torque, though the single-carburetor system could be a challenge in maintaining optimal performance across varying loads. With an oil capacity of 13 quarts, regular maintenance is key to prolonging engine life, particularly in prolonged operation scenarios.

TRANSMISSION
The Cletrac AG tractor features a [-|-] gear type with a simple transmission system offering 3 forward and 1 reverse gear, allowing for straightforward operation in various agricultural tasks. The dry disc clutch provides reliable engagement and disengagement mechanics but may require more maintenance compared to wet clutches in heavy-duty applications. Its design is ideal for smaller-scale farming where versatility and ease of use are prioritized, though it may pose challenges in terms of power delivery under high-load conditions.

MECHANICAL
The Cletrac AG tractor features a crawler chassis, which provides superior traction and stability on uneven terrain, ideal for agricultural applications. Its mechanical clutched steering allows for precise maneuverability, although it may require more physical effort from the operator compared to hydraulic systems. The open operator station promotes visibility and airflow but may expose the operator to harsh weather conditions and debris.
