The transmission is a hydraulically engaged four speed forward, three speed reverse countershaft type power shift transmission. A caliper-disc type parking brake is located on the front axle. The transmission outputs through universal joints to three drive shaft assemblies. The front drive shaft is a telescoping shaft which drives the front axle. The front axle is mounted directly to the loader frame. The front axle is equipped with hydraulic lock differential. The rear axle is mounted on an oscillating pivot. The rear axle is equipped with conventional differential. The power transmitted to front axle and rear axle is reduced by the pinion gear and ring gear of differential. It then passes from the differential to the sun gear shaft (axle shaft) of final drive. The power of the sun gear is reduced by a planetary mechanism and is transmitted through the planetary hub to the wheel. Identify the Tier Level of your Equipment (Read our Article on Tier Level )
