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 and approved only with the equipment originally provided or recommended by the manufacturer.

The below-mentioned boxes are included in this workshop handbook, as is appropriate.

WARNING! 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 eye protection when working with tensioned springs.

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.

IMPORTANT INFORMATION

This box indicates a risk of damage to the material if the instructions are not followed.

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.

Use eye protection when working with the battery with the plugs removed. 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.

IMPORTANT INFORMATION

Waste oil and old filters shall be handled as hazardous waste.

• Fit the lock nut on the socket head cap screw.

Tow plate

The tow plate is fitted the “wrong way round” at the factory for transport reasons. Fit the tow plate on the rear bumper as shown in the diagram.

Check the oil level in the engine

Check the oil level in the engine when the Rider stands horizontal with the engine switched off.

Lift up the engine cover.

Loosen the dipstick and pull it out. Wipe the dipstick and replace it.

The dipstick should be screwed fully down.

Loosen the dipstick and pull it out again. Check the oil level.

The oil level should lie between the markings on the dipstick. If the level is close to the “ADD” mark, top up with oil to the “FULL” mark on the dipstick.

The oil is poured in the same hole the dipstick fits in.

Fill the oil slowly. Tighten the dipstick correctly before starting the engine. Start and run the engine at idling speed for approx. 30 seconds. Turn off the engine. Wait 30 seconds and check oil level. If necessary fill so that the oil comes up to the ”FULL” mark on the dipstick.

Use engine oil SAE 30 or SAE 10W/30, class SFCC on all machines up to 2002 models as well as later models of Rider 11 and 13 with side-valve engines.

Rider 16, 2003 model

ADD

FULL

From 2003 Rider 16 models use first and foremost synthetic engine oil class SJ-CF 5W/30 or 10W/30, otherwise SAE30, class SF-CC.

Checking the oil level in the transmission

(Not Rider 11)

Remove the transmission cover. Loosen both screws (one on each side) and lift off the transmission cover.

Check that there is oil in the transmission’s oil tank. Fill if necessary with engine oil SAE 10W/30 (class SF–CC).

IMPORTANT INFORMATION

Delivery measures

Check and top up with oil after each test drive. The oil level will drop if there are air pockets in the transmission.

Wheels

Fit the wheels (certain markets). The tyre pressures should be 60 kPa (0,6 kp/cm2 /8,5 PSI) on all the wheels. To improve the driving capacity the pressure in the back tyres can be reduced to 40 kPa (0,4 kp/cm2 /5,6 PSI). Maximum permitted pressure is 100 kPa (1,0 kp/cm2 /14 PSI).

IMPORTANT INFORMATION

Different pressures in the front tyres will cause the blades to cut the grass at different heights.

Checking and adjusting of the mowing deck’s ground pressure and parallelism

Carried out after checking the tyre pressures. See respective sections in this Workshop Manual.

Engine

These Husqvarna Riders have single-cylinder, aircooled engines from Briggs & Stratton.

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 28B707 Rider 13 286707 Rider 16 -2002 28N707 Rider 16 2003- 282H070110

Rider 11 and Rider 13 are fitted with a single cylinder side-valve engine of 10.5 resp. 12.5 hp with splash lubrication. Rider 16 is fitted with a single cylinder overhead-valve engine of 15.5 hp. A new overhead-valve engine with AVS (Anti Vibration System) has been introduced from 2003 models.

Steering

Design and function

All the ride-on mowers in the 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 (8"-12")depending on which model is chosen.

Rider machines have a sliding bearing (1) on the steering column.

Driving

Rider 11 has a manual gear box with five forward gears, neutral and one reverse gear. This gear box is an "inline" type, which means that you can change from neutral to fifth gear without having to go through all the other gears.

Rider 13 and Rider 16 are equipped with hydrostatic transmission which provides the driver complete control. Continuously variable speed control, forwards and reverse, is by means of a pedal.

Mowing deck

The entire Rider series is equipped with frontmounted mowing decks to ensure effective cutting even in confined areas.

Rider 11 and Rider 13 have a mowing deck with rear ejection and a cutting width of 850 mm (34").

Rider 11 Bio and Rider 13 Bio have a Bio deck with a cutting width of 900 mm (36").

20 – English

Rider 16 can be fitted with mowing decks with either side or rear ejection where both have mowing widths of 970 mm (38"), BioClip unit with mowing width 900 mm (36") alternatively 1030 mm (41") or Combi unit 1030 mm (41") alternatively 1120 mm (44"). The Combi unit works as a BioClip unit when a BioClip plug is fitted, but can be modified for rear ejection by removing the BioClip plug.

Design and function

The mowing deck is raised and lowered using the mechanical lifting lever, which actuates a shaft that rotates. When the shaft rotates, the chain that is secured in an arm on the inner end of the shaft raises or lowers the tool frame.

The attachment’s lifting device

When lowering the unit, the two connecting rods, via the three-point link, will alter the belt adjuster so that the drive belt is tensioned and the blades begin to rotate. When the attachment is raised the microswitch in the safety circuit is actuated.

The mowing deck is rear suspended with the lug on the rear transverse axle in a U-bracket on the tool frame. The front of the tool frame is linked to a bracket on the attachment. The front rollers are supported against the ground, for example, when turning when the attachment tends to lean. The rollers on the rear section of the protective frame are used when removing and fitting the mowing deck or moving it to the service position. Otherwise, when dismantling, the rear of the attachment would fall directly to the ground when the lug on the rear axle releases its grip.

The mowing height is adjusted using the lever, which has a catch for the different mowing height positions. The setting for the mowing height range is located on the same axle, see ”Adjustment of the mowing height range”. Two connecting rods via a

toggle joint actuate the protective frame around the mowing deck and raise or lower the mowing deck’s cover within the mowing height range.

There are two struts on the top of the cutting unit cover. The upper one is coupled between the horizontal connecting rod and the tongue of the forward perpendicular shaft on the top of the mowing deck cover. When the shaft is rotated, it will raise or lower the cutting unit cover in relation to the protective frame. The lower strut (parallel strut) is connected between the front and rear transverse axles, so that even the rear axle rotates in the same way as the front axle. There is an adjuster on the parallel strut to adjust the mowing deck cover’s parallelism with the ground. See ”Checking and adjusting the mowing deck’s the parallelism”.
