Presentation

Congratulations on your choice of an excellent quality product that will give you great pleasure for many years. This operator???s manual describes Rider 175 and Rider 175 AWD.

The machines are equipped with a 17,5 horse power engine from Briggs & Stratton.

Rider 175 AWD is equipped with all wheel drive.

The power transmission from the engine is handled by a hydrostatic gearbox, which allows variable variation of the speed by using the pedals.

One pedal for driving forward and one for reverse.

Throttle control/choke control

The throttle control regulates the engine speed, and thereby also the rotation speed of the blades.

The control is also used to activate the choke. When the choke is engaged a richer fuel and air mixture is fed to the engine, which facilitates starting in the cold.

Speed limiter

The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards, and pedal (2) to drive backwards.

2 1

WARNING! Make sure that branches do not

!obstruct the pedals when mowing under bushes. Otherwise there is a risk you may lose control.

Parking brake

The parking brake is applied as follows:

1Press down the parking brake pedal (1).

2Press in the lock button (2) on the steering column.

3Release the parking brake pedal while keeping the button pressed in.

The parking brake lock disengages automatically when the brake pedal is pressed.

Cutting unit

Rider 175 and 175 AWD can be equipped with two different cutting units.

???Combi 1030mm/41???

???Combi 1120 mm/44???

The Combi-unit, equipped with a BioClip-plug, ???nely chops the cuttings to fertiliser. Without the BioClip-plug the unit works in the same way as a rear ejection unit.

Lifting lever for the cutting unit

The lift lever is used to set the cutting unit in transport or mowing position.

If the lever is pulled backwards the unit is raised and the blades automatically stop rotating (transport position).

If the lock button is pressed in and the lever is moved forwards the unit will be lowered and the blades will automatically start to rotate (mowing position).

The lever can also be used to temporarily regulate the cutting height, e.g. for a small mound in the lawn.

Cutting height adjustment lever

The cutting height can be adjusted to 7 different positions with the cutting height lever.

Combi-unit 40-90 mm (1 9/16??? - 3 9/16???)

Seat

The seat has a jointed attachment on the front edge and can be tipped forward.

The seat can also be adjusted lengthways.

Loosen the handles under the seat and adjust it forwards or backwards to the desired position.

Fuelling

The engine runs on unleaded petrol with a minimum octane rating of 85 (not mixed with oil). We recommend the use of biodegradable alkylate petrol. (max. methanol 5%, max. ethanol 10%, max. MTBE 15%)

Do not ???ll the tank completely, leave an expansion area of at least 2.5 cm (1???).

WARNING! Petrol is highly in???ammable.

!Exercise care and refuel outdoors (see safety instructions).

IMPORTANT INFORMATION Do not use the fuel tank as a support area.

Release lever

The release control must be pulled out in order for the machine to be moved when the engine is shutoff.

Should you attempt to drive the machine with the clutch controls pulled out it will not move. The drive on the axle is disengaged when one of the controls is pulled out.

2Lift up the cutting unit by pulling the lever backwards to locked position (transport position) and apply the parking brake.

Rider 175 AWD The engine can not be started if the parking brake is not pressed down.

Starting a cold engine

3Move the throttle to position 3 (choke position). In this position the engine is fed with a richer mixture, which means the engine is easier to start.

Starting a warm engine

Move the throttle in between positions 1 and 2.

4Turn the ignition key to the start position.

5When the engine starts release the ignition key immediately back to neutral position.

IMPORTANT INFORMATION

Do not run the starter for more than about 5 seconds at a time. If the engine does not start, wait about 15 seconds before trying again.

6Push the throttle control to full throttle position. Let the engine run at moderate speed or half throttle for 3-5 minutes before subjecting it to heavy load.

7Set the required engine speed with the throttle control.

WARNING! Never run the engine indoors, in

!enclosed or poorly ventilated areas. The exhaust fumes contain toxic carbon monoxide.

Starting the engine with a weak battery

WARNING! Lead-acid batteries produce

!explosive gases. Avoid sparks, open ???ames and smoking close to batteries. Always wear protective glasses in the vicinity of batteries.

If the battery is too weak to start the engine, it should be recharged.

When jump leads are used for emergency starting, follow the procedure below:

IMPORTANT INFORMATIONYour Rider is equipped with a 12-volt system with negative earth. The other vehicle must also have a 12-volt system with negative earth. Do not use your Rider battery to start other vehicles.

Connecting the jump leads

???Connect each end of the red cable to the POSITIVE pole

(+) on each battery, exercise care not to short circuit any of the ends against the chassis.

???Connect one end of the black cable to the NEGATIVE pole (-) on the fully charged battery.

???Connect the other end of the black cable to a good CHASSIS EARTH, away from the fuel tank and the battery.

Remove the cables in the reverse order

???The BLACK cable is removed from the chassis and then the fully charged battery.

???Finally the RED cable from both batteries.

Driving the Rider

1Release the parking brake by ???rst pressing down the parking brake pedal and then releasing it.

2Carefully press down one of the pedals until the required speed is obtained. Pedal (1) is used to drive forwards, and pedal (2) to drive backwards.

2 1

3Select the required cutting height (1-7) with the cutting height lever.

It is important that the air pressure in both front wheels is equal, 60 kPa / 0,6 bar / 8.5 PSI, to produce an even cutting height.

4Press in the lock button on the lifting lever and lower the cutting unit.

IMPORTANT INFORMATION

The life span of the drive belts is increased signi???cantly if the engine runs at a low speed when the blades are engaged. Therefore apply full throttle ???rst when the cutting unit has been moved to the mowing position.

Cutting tips

WARNING! Clear the lawn from stones and

!other objects which can be thrown out by the blades.

???Localise and mark stones and other ???xed objects to avoid collision.

???Start with a high cutting height and reduce down until the required mowing results are obtained.

???The mowing result will be best with the highest permitted engine speed, see technical data, (the blades rotate rapidly) and low speed (the Rider moves slowly). If the grass is not too high and thick, the driving speed can be increased without noticeably depreciating the mowing result.

???The best lawns are achieved if the grass is cut often. Mowing becomes more uniform and the grass cuttings become more evenly distributed over the surface. The total time consumption is not greater since it is possible to select a higher driving speed without inferior mowing results.

???Avoid mowing a wet lawn. The mowing results are inferior since the wheels sink down into the soft lawn.

???Hose down the cutting unit with water underneath each time it is used. The cutting unit should then be put in the service position.

???When the BioClip function is used, it is very important that the mowing interval is not too long.

WARNING! Do not use the machine on

!ground that slopes more than 10??. Mow slopes upwards and downwards, never across. Avoid sudden changes in direction.

Stop the engine

Preferably allow the engine to idle for a minute to obtain normal working temperature before stopping it if it has been working hard. Avoid idling the engine for long periods, as there is a risk of carbon build-up on the spark plugs.

1Lift up the cutting unit by pulling the lever backwards to its locked position.

2Move the throttle control to the MIN. position. Turn the ignition key to the ???STOP???.

3When the Rider is at a standstill, press down the parking brake and push in the locking button.

Cleaning

Clean the machine directly after use. It is much easier to wash off grass cuttings before they dry.

Oily dirt can be removed using a cold degreasing agent. Spray on a thin layer.

Rinse at normal water pressure.

Do not direct the jet towards electrical components or bearings.

Do not rinse hot surfaces such as the engine and exhaust system.

It is recommended that you start the engine and run the mower for a short period after cleaning, so that any remaining water is blown off.

Lubricate the machine if necessary after cleaning. Carry out extra lubrication when the bearings have been exposed to a degreaser or a water jet.

IMPORTANT INFORMATION

Avoid using a high pressure washer or a steam cleaner.

There is a major risk of water penetrating into bearings and electrical connections. Corrosion attack can result, which will lead to running problems. Cleaning additives generally aggravate the damage.

4Place a set of bathroom scales under the cutting unit???s frame (front edge) so that it rests on the scales. If necessary a block can be placed between the frame and scales so that the support wheels do not bear any weight.

5Adjust the unit???s ground pressure by screwing in or out the adjusting screws located behind the front wheels on both sides.The ground pressure should be between 12 and 15 kg (26.5-33 lb).

Checking the cutting unit???s parallelism

Check the cutting unit???s parallelism as follows:

1Check the air pressure in the tyres 60 kPa/0.6 kp/cm2/8.5 PSI.

2Place the machine on a ???at surface.

3Put the lifting lever in the mowing position.

4Measure the distance between the ground and the front and rear edges of the cutting unit hood. The cutting unit should have a slight slant, with the rear edge 2-4 mm (1/ 8???) higher than the front edge.

Adjusting the parallelism of the cutting unit

1 Remove the front hood and right-hand fender.

2Undo the nuts on the lift strut.

3Screw out (extend) the stay to raise the rear edge of the cover.

Screw in (shorten) the stay to lower the rear edge of the cover.

4Tighten the nuts after adjustment.

5On completion of the adjustment the unit???s parallelism should be re-checked.

6Fit the right-hand fender and the front hood.

6Place a foot on the front edge of the cutting unit near the wheel and raise the front edge of the unit to make it easier to remove the lift strut.

7Engage the strut in the holder.

WARNING! Observe caution to avoid

!trapping your hand.

8Lift of the drive belt. Then pull out the pin.

9Pull the frame forwards and re???t the pin.

10Grasp the front edge of the cutting unit, pull out and raise into the service position.

If the cylindrical bolt, which is now holding the cutting unit is removed, the cutting unit can be lifted off.

Restoring from service position

To leave the service position, reverse the procedures set out in Placing in the service position. Make sure that the cutting unit???s ???lug??? (3) enters the loop correctly on the underside of the machine, see diagram.

Checking the engine???s oil level.

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

Open the engine cover.

Loosen the dipstick, pull it up and wipe it off.

Now insert the dipstick again. The dipstick should be completely screwed down

Pull the dipstick out again and read the oil level.

The oil level should be between the markings on the dipstick. If the level is approaching the ADD mark, top up the oil to the FULL mark on the dipstick.

ADD FULL

The oil is topped up through the hole the dipstick sits 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 the oil level. If necessary ???ll so that the oil comes up to the FULL mark on the dipstick.

First and foremost use synthetic engine oil class SJ-CF 5W/ 30 or 10W/30 for all temperature ranges. Mineral oil SAE30, class SF???CC can be used at temperatures > +5 ??C (40 ??F)

Do not mix different types of oil.

Caution when using oils such as 5W-20, 10W-30 and 10W-40 the engine???s oil consumption increases. If these oils must be used, check the oil level frequently.

Replacing the engine oil

The engine oil should be changed the ???rst time after 5 hours running time. It should then be changed after every 50 hours of running time. When operating with a heavy load or at high ambient temperatures, replace every 25 hours.

WARNING! Engine oil can be very hot if it is

!drained directly after stopping the engine. Allow the engine to cool somewhat ???rst.

1 Place a container underneath the engine???s left oil drain plug.

2Remove the dipstick. Remove the drain plug from the engine???s left side.

3 Let the oil run out into the container.

4Fit the drain plug and tighten it.

5If necessary ???ll so that the oil comes up to the FULL mark on the dipstick. The oil is topped up through the hole the dipstick sits in. See Checking the engine???s oil level for ???lling instructions. The engine holds 1.4 litres (1.5 USqt) when the oil ???lter is not replaced and 1.6 litres (1.7 USqt) of oil when the oil ???lter is replaced.

6Run the engine warm, then check that there is no leakage from the oil plug.

IMPORTANT INFORMATION

Used engine oil is a health hazard and must not be disposed of on the ground or in nature; it should always be disposed of at a workshop or appropriate disposal location.

Avoid skin contact; wash with soap and water in case of spills.

Changing the oil ???lter

The oil ???lter must be replaced after every 200 hours running time. Turn the old oil ???lter anti-clockwise to remove. If necessary, use a ???lter remover.

Lightly lubricate the rubber seal on the new oil ???lter using new oil. Fit the oil ???lter by turning clockwise. Turn by hand until the rubber seal is seated. Now tighten a further half turn.

Fill with new oil according to Checking the engine???s oil level. Start the engine and let it idle for about 3 minutes. Now stop it and check for signs of leakage. Fill with oil to compensate for the oil held in the new oil ???lter.

Checking the transmission oil level

1Remove the transmission cover. Undo the two screws (one on each side) and lift off the transmission cover.

2Check that there is oil in the transmission???s oil tank.

Rider 175 Fill if necessary with engine oil SAE 10W/30 (class SF???CC).

Rider 175 AWD Fill if necessary with engine oil SAE 10W/ 40 (class SF???CC).

The oil and ???lter should be changed by an authorised service representative, as described in the Workshop Manual.

Work on the system entails particular demands on cleanliness and the system must be vented before the machine is used.

Lubricating the belt adjuster

The belt adjuster should be lubricated regularly using good quality molybdenum disulphide grease*.

Lubricate using a grease gun, 1 nipple from the right-hand side under the engine???s lower belt pulley, until grease is forced out.

With daily use, lubrication should be carried out twice weekly.

General lubrication

All joints and bearings are lubricated using molybdenum disulphide grease during manufacture. Continue to lubricate using the same type of grease *. Lubricate the steering and control wires using engine oil.

Carry out this lubrication regularly; with daily use, the machine should be lubricated twice weekly.

*Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality. The most important property is that the grease provides good protection against corrosion.

Winter storage

At the end of the season, or if the machine is going to stand idle for more than 30 days, it should immediately be made ready for storage. Fuel which is left to stand for long periods (30 days or more) can leave tacky deposits which can block the carburettor and interfere with the engine.

Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage. If alkylate petrol (Aspen) is used stabiliser is not necessary since this fuel is stable. However, one should avoid changing from standard to alkylate petrol since sensitive rubber parts can harden. Add stabiliser to the fuel in the tank or the storage container. Always use the mixing ratios indicated by the manufacturer. Run the engine for at least 10 minutes after adding the stabiliser so that it will reach the carburettor. Do not empty the fuel tank and carburettor if stabiliser has been added.

WARNING! Never place an engine with fuel

!in the tank indoors or in poorly ventilated areas where petrol fumes can come into contact with naked ???ames, sparks or pilot ???ames in boilers, hot water heaters, drying cabinets, etc. Exercise caution when handling fuel. It is highly in???ammable, and careless use can cause serious injury and damage to property. Drain off the fuel in an approved container outdoors and well clear of naked ???ames. Never use petrol for cleaning purposes. Use degreasing agents and hot water instead.

To prepare the machine for storage follow these instructions:

1Carefully clean the machine, especially under the cutting unit. Touch-up paint damage to avoid rust.

2Inspect the machine for worn or damaged parts and tighten loose screws and nuts.

3Change the engine oil, and take care of the waste oil.

4Empty the fuel tank. Start the engine and run it until the carburettor is emptied of fuel.

5Remove the plugs and pour about a tablespoon of engine oil into each cylinder. Pull round the engine to distribute the oil and screw the plugs back on.

6Grease all grease nipples, joints and axles.

7Remove the battery. Clean it, charge it, and store it in a cool place.

8Store the machine in a clean and dry place and cover it over for extra protection.

Guard

There is a cover to protect your machine during storage or transport. Contact your dealer for a demonstration

Service

Low season is the most suitable time to perform a service or overhaul of the machine in order to ensure high function safety during high season.

When ordering spare parts state your machine???s purchase year, model, type, and serial number.

Always use genuine parts.

Annual inspection or tuning by an authorised service workshop is a good way of getting the best out of your machine the next season.
