Introduction
Groundsmaster® 300 Series traction units are equipped
with a Dana Hydrostatic Axle, model GT-20. The differ•
ential and axle form the final drive of the power train
(Fig. 1A).
The differential has a heavy duty case with automotive
type, cut gears that rotate on tapered roller bearings.
Single-row, pre-set, tapered roller bearings are used on
the outside ends of the axle shafts.
The entire drive line of the axle assembly is made of
alloy steel. The axle has a die-cast aluminum housing
that also serves as the hydraulic oil reservoir.
Power is transmitted from the transmission output gear
to the pinion spur gear. The pinion spur gear transmits
power directly to the differential drive gears, to turn the
axles and the wheels.
The differential axle has a one-piece axle shaft with the
flange being part of the axle stem (Fig. 1B).
