Introduction - Husqvarna P 520D Workshop Manual

Husqvarna P520D/P525D is a professional machine
for professional use on large areas of land. It can be
equipped with accessories for mowing, clearing
snow, sweeping, etc.
This Workshop Manual is intended as an aid for
personnel with general knowledge of the repair and
service of P520D/P525D. Service for this machine
requires knowledge corresponding to vocational
training for automotive mechanics with machinery
or automobile specialty.
Modifications to the machine can be gradually
introduced into ongoing production. As these
modifications affect service and/or spare parts,
specific service information will be sent out on each
occasion. This means this Workshop Manual can in
time become out of date. In order to prevent this, the
Manual should be read together with all service
information concerning the ride-on mower in
question.
This Workshop Manual covers model years from
2011 and later. It concerns the machine including
removal and assembly of sub-contractor
components. For dismantling/assembling, adjusting
and testing sub-contractor components, please refer
to the manuals published by the respective
manufacture.
