TRANSMISSION 1

The Kubota GL320 tractor features a versatile 16-speed transmission with four main gears across two ranges (low/high) and a creeper range, which enhances its ability to operate in various agricultural scenarios, such as tilling and hauling at different speeds. The shuttle shift allows quick direction changes, improving maneuverability in tight spaces. However, the use of a dry disc clutch may require more maintenance compared to wet clutches, particularly under heavy load conditions.
