Safety regulations
General instructions
The workshop handbook is written for personnel who
are assumed to have general ride-on mower reparation and service know-how .
The workshop where the ride-on mower is repaired
should be equipped with safety devices in
accordance with local regulations.
No-one should attempt to repair the ride-on mower
without having first read and understood the contents
of this handbook.
The machine is tested for safety and approved only
for equipment supplied or recommended by the
manufacturer.
The below-mentioned boxes are included in this
workshop handbook, as is appropriate.
WARNING!
!
IMPORTANT INFORMATION
This box indicates a risk of damage to the
material if the instructions are not
followed.
The warning box indicates a
risk of injury to persons if the
instructions are not followed.
Special instructions
The fuel used in the ride-on mower has the
following hazardous characteristics:
• Toxic fluid and fumes
• Can cause eye and skin complaints
• Can cause breathing difficulties
• Highly flammable
When using compressed air, do not direct the
compressed air stream towards your, or anybody
else's, body. Air can be forced into the blood
stream, thereby constituting a danger to life .
Use hearing protectors when test driving.
After test driving, do not touch the silencer before it
has cooled down. Risk of burn injuries. This
especially applies if the ride-on mower is equipped
with a catalytic converter. If consumed, the lining on
and in the catalytic converter element is dangerous
to health. Use protective gloves when working with
the catalytic converter/silencer.
The blades are sharp and can cause cutting
injuries. Always use protective gloves when you are
handling the blades.
Use protective glasses when working with the
mowing deck. If the belt's tension spring comes off
and flies upwards, this can cause injury to persons.
2 – English
Be extra careful when handling battery acid. Spilling
acid on the skin can cause severe burn injuries. If
acid is spilt on the skin, rinse immediately with
water. If acid gets into the eyes, this can cause
blindness. Contact a doctor.
Be careful with the maintenance of the battery.
Explosive gas is formed in the battery. Never
handle the battery when smoking or in the vicinity of
naked flames or sparks. Otherwise, the battery can
explode and cause severe injuries.

General
Husqvarna Riders is a series of ride-on mowers
with a large capacity. There are six sizes, from the
smallest Rider 11 to the largest Rider 20 ProFlex.
This manual refers mainly to the smaller machines;
the larger ProFlex machines are covered by a
separate manual. All Riders have articulated
steering in order to easily cut around trees and
other obstacles. Moreover, they all have frontmounted mowing decks for controlled cutting and
for best possible cutting results.

Engine
All Husqvarna Riders have engines from Briggs &
Stratton. The Rider 11/11 Bio, Rider 13 H/13 H bio
and Rider 16 H have single-cylinder engines, while
the Rider 14 Pro has a twin-cylinder engine. Both
the single and two-cylinder engines are air cooled.
More intricate engine repairs are not described in
this workshop handbook, these can instead be read
in Briggs & Stratton's own handbooks which contain
detailed information about adjusting and repairing
the engines. The handbooks can be ordered from
an authorized service workshop.
The order numbers for the respective Rider models
are found in the table below. Please state these
when ordering manuals:
Model B & S model no.
Rider 11/11 Bio 28B707
Rider 13 H/13 H Bio 286707
Rider 14 Pro 294777
Rider 16 H 28N707
It is important that only original spare parts are
used when repairing the engines. If other parts are
used, the guarantee shall no longer be valid.
Rider 11/11 Bio and Rider 13 H/13 H Bio have a
single-cylinder side valve engine with spray
lubrication with power outputs of 10.5 and 12.5 hp
respectively.
Rider 16 H has a 15.5 hp single-cylinder overhead
valve engine.
The Rider 14 Pro has a twin-cylinder overhead
valve engine with pressure lubrication and a
separate oil filter. This engine is equipped with a
catalytic converter that reduces emissions of
hydrocarbons and nitrogen oxides by up to 65%
and reduces carbon dioxide by up to 45%.

Design and function
Steering
All the ride-on mowers in Husqvarna's Rider-series
have articulated steering. The steering force from
the steering wheel is transferred to the rear section
via wires and a chain. This ensures that the ride-on
mower is easy to manoeuvre, as well as having
high-precision steering. A Rider easily cuts around
all obstacles that may be found on the lawn.
Thanks to the articulated steering, the turning
radius is extremely small, the uncut circle when the
steering wheel is fully turned is just 20–30 cm
depending on which model is chosen.
Outline diagram of the articulated steering function.
Rider machines have a sliding bearing (1) on the
steering column.

Design and function
Driving
Rider 13 H/13 H Bio, Rider 16 H, Rider 14 Pro are
equipped with hydrostatic transmission which
provides the driver complete control. Continuously
variable speed control, forwards and reverse, is by
means of a foot pedal.
Rider 11 and Rider 11 Bio have a manual gear box
with five forward gears, neutral and one reverse
gear. This gear box is an "inline" type, which means

Changing the oil
The engine oil should be replaced after the first five
hours of running time, see service chart. Thereafter
it should be replaced every 50 hours of running
time (25 hours in harsh operating conditions).
WARNING!
!
Engine oil can be very hot if it is
drained off directly after the engine
is stopped. Therefore allow the
engine to cool down first.
Checking and adjusting steering wires
1
Remove the frame plate by releasing the screws
(two on either side).
2
Drain plug on Rider 11/11 Bio, Rider 13 H/13 H Bio and
Rider 16 H
Tip! When draining the engine oil use a folded
piece of cardboard to funnel the oil into the container.
Drain plug on Rider 14 Pro
Place a container under the drain plug on the left
side of the engine.
Remove the dipstick and drain plug. Let the oil
drain into the container.
Refit the drain plug and tighten it.
Fill with oil up to the “FULL” mark on the dipstick.
Pour the oil into the same hole the dipstick goes in.
Use engine oil SAE 30 or SAE 10W/30, class CDSF.
Run the engine until warm, then check that there
are no oil leaks from the drain plug.
The tension is checked by squeezing together the
wires (as shown in the diagram). Without having to
apply too much force, the wires should be able to
be squeezed to half the distance between them.
3
Stretch the wires by tightening the adjuster nuts
(one wire on each side of the ride-on mower). Do
not overtension them, they should only be tightened
up to the steering rim. Stretch both wires equally so
that the steering wheel position is not changed.
Check the wire tension after adjustments have
been made, in accordance with point 2.

Hydrostatic transmission brake
Removal of brake
1
• Place blocks in front of and behind the wheels so
that the ride-on mower can not roll. Then, release
the parking brake.
• Remove the split pin and the washer from the
brake's connecting rod (1).
• Remove the three bolts and washers (2) from the
transmission and detach the brake lining packet.
Installation of brake
1
• Put the brake drum on the axle and attach the
circlip.
• Assemble the brake lining packet on the transmission and tighten the three bolts and washers
by hand
• Press the brake lever (1) backwards so that the
brake lining locks the drum, and draw the three
bolts with moment to 27 Nm (20 ft, lbs.), whilst
the drum is locked.

• Firmly attach the brake's connecting rod in the
hole on the brake lever and assemble the washer and spring clip.
• Remove the blocks in front of and behind the
wheels and continue with “Adjusting brake”.
IMPORTANT INFORMATION
Firmly attach the connecting rod so that the
washer and the spring clip are on the
outside of the brake lever (see diagram).
Adjustment of brake
1
Apply the parking brake and check that the
transmission's brake arm is pulled as far forwards
as possible (see diagram). Adjust this with the
brake wire tensioning screw (see “Checking and
adjusting brake wire”).
When the parking brake is fully applied, the gap
between the spring and the spring holder
attachment (see diagram) should be 4–8 mm.
3
Adjust the gap by:
• Releasing the parking brake.
• Loosening the connecting rod by removing the
spring clip and the washer.
• Turning the connecting rod in or out of the spring
(see diagram) to adjust the gap.
• Firmly attach the brake's connecting rod in the
hole on the brake lever and assemble the washer and spring clip. Make sure that the washer
and spring clip are on the outside of the brake
lever.
• Apply the parking brake and check the gap once
again.
• Repeat the adjustment procedure until the
correct gap is obtained.
Ineffective brake power
As the brake is only used as a parking brake, wear
is negligeable. If the brake power is nevertheless
ineffective, this can be adjusted:
• Release the three bolts (N12) which hold the
brake lining packet.
• Press on the brake lever so that the brake lining
centres itself around the brake drum and tighten
the three bolts with moment (27 Nm).

Transmission maintenance
Oil change
Most garden owners do not have tools for or
experience of changing transmission oil. The
transmission probably has a longer operational life
than other ride-on mower components, this makes
transmission oil changes less important for most
customers. However, the transmission's operational
life is increased if oil changes are made.
If the ride-on mower is used
recommended to change the oil firstly after 50
hours use and every 300 hours use thereafter.
The oil filter only needs to be changed if the transmission is opened for repairs to be made.
