DESIGN AND FUNCTION

Engine

The Husqvarna Rider ProFlex series
comprises professional machines with twin-
cylinder, air-cooled Kawasaki engines.

Major engine repairs are not described in this
workshop manual. This information can be
found in Kawasaki’s manuals, which contain
detailed information about adjusting and
repairing the engines. These manuals can be
ordered from an authorised service
workshop.

The table below contains the model numbers
for the different Rider models. These should
be stated when ordering manuals:

Model

Kawasaki’s
engine type

Rider Pro 18 AWD

FH531V-DS50

Rider ProFlex 21 AWD

FH641V-DS50

It is important that only original spare parts
are used to repair the engines. If other parts
are used, the guarantee is invalidated.

The machines have twin-cylinder, overhead
valve engines with pressure lubrication and
separate oil filters. The engine is equipped
with a catalytic converter, which reduces
hydrocarbon and nitrogen oxide emissions by
up to 65% and carbon monoxide emissions
by up to 45%.
