TRANSMISSIONS OVERVIEW

The Kioti RX6620 features a 12-speed synchro shuttle, allowing seamless gear shifting for enhanced operational efficiency, particularly in applications requiring frequent directional changes, such as loader work. The power shuttle system provides the advantage of quick direction changes without clutch engagement, improving productivity in field tasks. However, operators should be aware that familiarity with the shuttle controls is crucial to maximize performance and minimize wear on transmission components.

TRANSMISSION 1

The Kioti RX6620 features a synchro shuttle transmission, allowing smooth shifts between forward and reverse, which enhances productivity in tasks requiring frequent directional changes. With 12 forward and reverse gears, operators benefit from precise speed control suited for diverse applications, although mastering the gear selection can be challenging for less experienced operators. The dry disc clutch system is reliable but may require more maintenance compared to oil-immersed systems, especially in heavy-duty operations.

Gears	12 forward and reverse
Clutch	dry disc

TRANSMISSION 2

The Kioti RX6620 features a power shuttle transmission, allowing for seamless direction changes without clutch disengagement, enhancing operational efficiency in varied field conditions. Its 12-forward and reverse gears offer versatility in speed and torque management, enabling precise power delivery for tasks ranging from heavy tilling to maneuvering in tight spaces. The wet disc clutch provides durability and reduced maintenance, ideal for intensive agricultural applications but may require additional initial investment.
