TRANSMISSION 1

The Yanmar AF-18 tractor features a robust 8-speed transmission with both forward and reverse gears, providing excellent maneuverability and adaptability for various agricultural tasks. This versatility is advantageous in tight spaces or when working on uneven terrain. However, operators should be aware of potential challenges in mastering gear shifting under varying load conditions, which may affect efficiency and performance.

Gears 8 forward and reverse

TRANSMISSION 2

The Yanmar AF-18 tractor features a creeper gear system, which allows for enhanced low-speed control, ideal for tasks requiring precision like tilling or planting. With 12 forward and reverse gears, it offers versatility in speed and torque management, catering to a variety of agricultural applications. However, the complexity of the gear system may require more maintenance and operator experience to fully utilize its capabilities in different terrain scenarios.
