Steering - Husqvarna Rider Pro 18 AWD Workshop Manual

Steering

All mowers in the Rider series have articulated
steering. Pro 18 AWD and ProFlex 21 AWD are
equipped with hydraulic servo steering. The
steering force from the steering wheel is
transmitted to the rear carriage via a chain and
cables. This makes steering the rider both easy
and precise.

The servo steering obtains its pressure from the
pump to the hydrostatic transmission. The power
steering is mounted in the steering column and its
stator section is fitted in the power steering
housing, which is the front section of the machine's
frame. The steering servo is, in principle, a
hydraulic torque motor that is controlled by the
DESIGN AND FUNCTION
A Rider easily cuts around all obstacles on the
lawn.
A mechanical linkage gives the front wheels a
higher speed when cornering.
The turning circle is very small thanks to the
articulated steering; the uncut circle with full lock is
only 20-30 cm / 8"-12" depending on model.
steering wheel. When there is no hydraulic
pressure, the machine can still be steered, as the
steering shaft is mechanically attached to the
sprocket wheel on the power steering's outgoing
shaft (the rotor section). See also "Component
