Driving - Husqvarna R 422 Ts Workshop Manual

Driving

The R 422 Ts is equipped with a hydrostatic
transmission that gives the driver complete
control over driving. The speed is controlled
using the forward or reverse pedals.
The AWD machines are equipped with
constantly engaged all wheel drive, which
means a differential lock is not required.
The hydraulic pump and transmission are
assembled as a unit.

The axle consists of a hydraulic motor,
differential and drive axles.
In order to move the machine without the
front axle's drive engaged, there is a
mechanical bypass valve that is operated by
a control on the inside of the left-hand wheel.
Rear axle on R 422 Ts AWD from the top.
Designed in principle as the front axle
To move the machine without the rear axle's
drive engaged, there is a hydraulic bypass
valve operated with a control behind the left
wheel.
The oil is drained using two plugs on the
underside. One plug drains the hydraulic
motor and the other drains the differential.
