| Gears | 12 forward and reverse |
| Description | Six synchronized gears in two ranges with hydraulic shuttle. The power shuttle was used on the M8580 with cab. |
TRANSMISSION 2
The Kubota M8580 features a mechanical shuttle transmission with 12 gears for forward and reverse operation, facilitating effective maneuverability in tight spaces. The requirement of a clutch to shift direction can be a drawback in high-traffic scenarios, affecting efficiency when frequent direction changes are needed. However, the synchronized gear design enhances operational smoothness, making it suitable for various agricultural tasks where control is paramount.
