ENGINE DETAIL
The Centaur AG-48, powered by a 140 ci (2.3 L) Le Roi D140 gasoline 4-cylinder engine, features a robust design with a bore and stroke of 3.50x3.625 inches (89 x 92 mm) for effective torque delivery at a low rated RPM of 1500. The oil bath air cleaner contributes to enhanced engine longevity by preventing dirt ingress, though it may require more maintenance compared to dry alternatives. This tractor is ideal for low-speed agricultural tasks but may face challenges in high-speed applications due to its design focus on torque rather than speed.

CENTAUR AG-48 ENGINE
The Centaur AG-48 tractor is powered by a Le Roi 2.3L 4-cylinder gasoline engine, offering a balance between sufficient power and efficient fuel consumption. Its smaller engine size may result in reduced torque compared to diesel counterparts, which could limit heavy-duty applications; however, it might excel in lighter agricultural tasks or smaller operations requiring maneuverability. Pros include lower initial costs and easier maintenance, but operators should consider the fuel economy and power limitations for specific farming scenarios.

TRANSMISSION
The Centaur AG-48 tractor features an unsynchronized transmission with a simplistic gear arrangement of 4 forward and 1 reverse, facilitating straightforward operation but potentially limiting speed variations. Its dry disc clutch provides efficient engagement with minimal maintenance; however, operators may experience heavier pedal effort compared to hydraulic options. This tractor is suitable for basic agricultural tasks where ease of use and reliability outweigh the need for advanced transmission capabilities.

| Gears | 4 forward and 1 reverse |
| Clutch | dry disc |
MECHANICAL
The Centaur AG-48 features a 4x2 2WD chassis, which provides simplicity and lower maintenance, but may struggle with traction on uneven terrain compared to 4WD models. Its 4-speed unsynchronized gear transmission allows for basic operation, although it may require more driver skill for gear changes, leading to potential operational delays. This configuration is ideal for light agricultural tasks on flat terrain, where maneuverability prevails over heavy-duty performance.

| Transmission | 4-speed unsynchronized gear |
CENTAUR AG-48 TIRES
The Centaur AG-48 tractor features a versatile tire configuration with 5.00-15 Ag front tires and 9-24 Ag rear tires, providing a balance of traction and stability. This setup is advantageous for light to medium agricultural tasks, allowing for maneuverability in tight spaces. However, the narrower tire width may pose challenges in muddy or uneven terrain, potentially resulting in soil compaction if not managed correctly.

DIMENSIONS & TIRES
The Centaur AG-48 tractor, with a weight of 2,700 lbs (1224 kg), provides a favorable power-to-weight ratio for light to medium agricultural tasks. Its front tires (5.00-15) offer agility for maneuvering in tight spaces, while the larger rear tires (9-24) enhance traction and stability on uneven terrain. However, the relatively lightweight may limit its performance in heavy-duty applications or on steep inclines, necessitating careful consideration for specific farming needs.
