TRANSMISSION 1
The Chery RK604 tractor features a shuttle transmission with 12 forward and reverse gears, allowing for excellent maneuverability in tight spaces and versatility in various farming applications. The 254mm dry disc clutch ensures reliable engagement and disengagement, reducing slippage during operation but may require more maintenance compared to wet clutches. Ideal for small to medium-sized operations, the RK604 is suitable for tasks such as plowing or hauling, though operators might find the clutch pedal effort heavier during extended use.
