TRANSMISSION
The Chamberlain 4490 tractor features a partial power shift transmission with 12 forward and 4 reverse gears, facilitating versatile speed control for various applications, but requires the tractor to be stopped for gear changes, which could limit operational efficiency in dynamic field conditions. The 15.5-inch dry disc clutch provides robust engagement but may necessitate maintenance under heavy use. With an oil capacity of 40.1 quarts (38.0L), proper lubrication is crucial for optimal transmission performance and longevity.

CHAMBERLAIN 4490 TIRES
The Chamberlain 4490 tractor features robust tire options with different configurations for 2WD and 4WD, ensuring optimal traction and versatility in varied agricultural environments. The 11.00x16 front tires for 2WD offer stability, while the 14.9x26 front tires in 4WD enhance maneuverability and weight distribution, particularly in soft soil conditions. However, the size disparity may affect the tractor's overall handling; thus, selecting the appropriate drivetrain is crucial based on soil conditions and intended application.

DIMENSIONS & TIRES
The Chamberlain 4490 tractor offers a broad weight range of 13,779 to 14,319 pounds, enhancing stability during operation, especially when utilizing rear 24.5x32 tires in 2WD mode. The 2WD fixed wheelbase of 113.5 inches may provide better maneuverability in constrained spaces, while the longer 4WD wheelbase of 115 inches improves traction on uneven terrain, making it suitable for heavier agricultural tasks. However, the trade-off between 2WD's agility and 4WD's traction must be evaluated based on specific operational scenarios, as 4WD may introduce higher wear rates on tires and components in certain conditions.
| 2WD fixed Wheelbas | 113.5inches / 288cm |
