TRANSMISSIONS OVERVIEW

The Kubota KT305 tractor features a 12-speed power shift transmission, which allows for smooth gear transitions and optimal power delivery under varying load conditions. This could enhance operational efficiency, especially in tasks requiring extensive speed adjustments, like plowing or cultivating. However, the complexity of the transmission may require more maintenance and operator training compared to simpler gear systems.

Description 12-speed 48-speed power shift

TRANSMISSION 1

The Kubota KT305 tractor features a 12-speed gear system with three gears across four ranges, enabling precise control in various field conditions via a shuttle shift mechanism. Its dry disc clutch can provide reliable engagement and disengagement, but may require more maintenance compared to wet clutches. This setup is advantageous for tasks demanding varied speed and torque, such as tilling or hauling, but may pose challenges for operations requiring frequent gear changes.

Gears 12 forward and reverse
Clutch dry disc
Description Three gears (1-3) in four ranges (creeper, low, medium, high) with shuttle shift

TRANSMISSION 2

The Kubota KT305 features a Glideshift power shift transmission with an impressive 48 forward and 30 reverse gears. The ability to shift sequentially without using the clutch in gear allows for smooth transitions during operation, which enhances productivity in variable conditions. However, the requirement to stop and clutch for range shifts could limit operational efficiency in dynamic environments, where quick adaptations are necessary.

Transmission Glideshift
Type power shift
Gears 48 forward and 30 reverse
Description Sixteen gears (10 in reverse) with three ranges. Gears may be shifted sequentially while moving, without using the clutch. Tractor must be stopped, and clutch used, to shift ranges

MECHANICAL

The Kubota KT305 features a robust 4x4 MFWD system, enhancing traction on diverse terrains, which is ideal for agricultural applications. The power steering and wet disc brakes provide improved handling and safety, while the optional air-conditioned cab ensures operator comfort during long hours. With a choice between a 12-speed and a 48-speed power shift transmission, it caters to various operational needs, optimizing performance for both light and heavy-duty tasks.
