Engine; Steering; Drive - Husqvarna P524 Workshop Manual

4.2 Engine

The machine has a twin-cylinder, overhead valve
engine with pressure lubrication and separate oil
filter.
It is important that only original spare parts are
used to repair the engine. If other parts are used,
the guarantee is invalidated.
Major engine repairs are not described in the
workshop manual. This information can be found
in the engine manufacturer's own manuals,
which include detailed information about engine
adjustments and repairs. Manuals can be ordered
from an authorized servicing dealer or downloaded
from the engine manufacturer's website. Specify the
engine's serial number when ordering the manual.

4.3 Steering

All ride-on mowers in the P500 series have
articulated steering. The machines are equipped
with hydraulic power steering. Steering forces from
the steering wheel are transferred to the rear
carriage via a hydraulic cylinder. This makes the
ride-on mower easy and precise to steer.
The control unit is connected directly to the steering
wheel and runs the steering cylinder, which is
connected between the chassis and the rear axle, in
and out. If the engine stops, it is still possible to
steer, but the wheel is heavy to turn.
The hydraulic tank is common to all hydraulic
functions on the machine.

4.4 Drive

The machine is equipped with hydrostatic
transmission which gives the driver complete driving
control. Speed is controlled variably using the pedals
forward or back.
The hydraulic pump and transmission are three
separate units.
Front and rear transmission
Front and rear transmission comprise a hydraulic
motor and a gearbox with differential and output
shafts. The hydraulic motor and the gearbox are
separated from each other and have separate oil
sources.
The hydraulic pressure must be released in order for
the machine to be moved when the engine is shutoff.
