Final Drive Travel Gearbox Fit for Excavator Kubota KX91-3

Product Introduction
A travel gearbox, also known as a final drive, is an essential component of an excavator that transfers power from the hydraulic motor to the wheels or tracks. The primary function of the travel gearbox is to provide torque and speed to propel the excavator forward or backward.
Installation and Functioning
The travel gearbox is installed in the middle of the undercarriage of the excavator and is responsible for driving the tracks. The gearbox uses gear reduction to convert the high speed, low torque power from the hydraulic motor to low speed, high torque power, which is then transmitted to the tracks.
