DESIGN AND FUNCTION
Engine
Husqvarna’s ride-on mowers for professional users have two-cylinder, air-cooled engines from Kawasaki.
Major engine repairs are not covered in this workshop manual. Users are referred to Kawasaki’s own 
manuals. These contain detailed information on the adjustment and repair of the engines. The manuals can 
be ordered from authorized service workshops.
The table below shows the information to be quoted when ordering engine manuals:
When repairing engines, use genuine spare parts only. The warranty will be invalidated if other parts are 
used.
Drive and Control
Via a belt, the engine supplies direct, clutchles, drive to two hydraulic pumps. The pumps have axial 
pistons.
Each pump feeds oil to a fixed (non-adjustable) hydraulic motor (one by each drive wheel). The rate and 
direction of oil flow is steplessly adjusted (via a mechanical linkage) by the motion control levers. 
Adjustment is actuated by a swash plate that regulates the stroke length of the hydraulic pistons. The swash 
plate is an integral part of each pump. The mower can be made to turn or reverse by controling the rate and 
direction of flow to the hydraulic motors. The hydraulic motors control the speed and direction of the drive 
wheels. To swing the mower around its center, simply drive one wheel forwards and the other backwards.
Hydrostatic braking occurs whenever there is no flow of oil from the pumps.
Instructions for the repair of the hydraulic pumps are given in the “Hydro-Gear BDP-10A/21L Service & 
Repair Manual”.
Brakes
Hydrostatic braking (see “Drive and Control”) 
provides brake control when the mower is 
being powered by its engine. Putting the 
motion control levers in the neutral position 
brakes the mower. To move the mower 
manually, open the air screws on the 
hydraulic pumps. Oil is then circulated by the 
hydraulic motors and the machine can be 
moved short distances at low speed.
The mower also has a park brake. This 
operates on both rear wheels. A brake band 
on each rear wheel is engaged by a lever on 
the left of the mower operator. The lever and 
the brake bands are mechanically linked.
