Steering - Husqvarna Rider PR 17 Workshop Manual

DESIGN AND FUNCTION

Steering

All mowers in the Rider series have articulated steering. The machines are equipped with hydraulic power
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.
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.

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 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 Locations PR 17, PF 21" on page 106.
