Driving on slopes

Driving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it.

IMPORTANT INFORMATION

Do not drive down slopes with the unit raised.

This is what you do

• Remove obstacles such as stones, branches, etc.
  Mow upwards and downwards, not sideways.

• Do not use the machine on ground that slopes more than 10^ .
• Avoid starting or stopping on a slope. If the tyres start to slip, stop the blades and drive slowly down the slope.
  Always drive smoothly and slowly on slopes.
• Do not make any sudden changes in speed or direction.
• Avoid unnecessary turns on slopes, if necessary, turn slowly and gradually downwards if possible. Drive slowly. Do not turn the wheel sharply.
• Watch out for and avoid driving over furrows, holes and bumps. It is easier for the machine to overturn on uneven ground. Tall grass can hide obstacles.

Take extra care if any attachments are fitted that can change the stability of the machine.
- Do not mow too close to edges, ditches or banks. The machine can suddenly overturn if one wheel comes over the edge of a steep slope or a ditch, or if an edge gives way.
- Do not mow wet grass. It is slippery, and tyres can lose their grip so that the machine skids.
- Do not try to stabilize the machine by putting your foot on the ground.
- When cleaning the chassis, the machine may never be driven near verges or ditches.

• When mowing, keep away from bushes and other objects.
• Follow the manufacturer's recommendations regarding wheel weights or counterbalance weights to increase machine stability.

IMPORTANT INFORMATION

Wheel weights fitted on the rear wheels are recommended when driving on slopes for safer steering and improved manoeuvrability. Consult your dealer concerning the use of wheel weights if you are unsure. Wheel weights can not be used on AWD-machines. Use counterweights.

Children

• Serious accidents may occur if you fail to be on your guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing. Never assume that children will remain where you last saw them.
• Keep children away from the area to be mowed and under close supervision by another adult.
• Keep an eye out and shut off the machine if children enter the work area.
• Before and during reversing procedures, look behind you and down for small children.
• Never allow children to ride along. They can fall off and seriously injure themselves or be in the way for safe manoeuvring of the machine.
• Never allow children to operate the machine.

• Be particularly careful near corners, bushes, trees or other objects that block your view.

Maintenance

• Stop the engine. Prevent starting by removing the ignition cable from the spark plug or remove the ignition key before making any adjustments or carrying out maintenance.
• Never fill the fuel tank indoors.

• Petrol and petrol fumes are poisonous and extremely flammable. Be especially careful when handling petrol, as carelessness can result in personal injury or fire.
  Only store fuel in containers approved for the purpose.
• Never remove the fuel cap and fill the petrol tank while the engine is running.
• Allow the engine to cool before refuelling. Do not smoke.
• Do not fill petrol in the vicinity of sparks or naked flames.
• Handle oil, oil filters, fuel and the battery carefully, of environmental considerations. Follow the local recycling requirements.
• Electrical shocks can cause injuries. Do not touch cables when the engine is running. Do not test the ignition system with your fingers.

WARNING! The engine and the exhaust system become very hot during operation. Risk of burn injuries if touched. When mowing, keep away from bushes and other materials in order to avoid a heating effect.

• If leaks arise in the fuel system, the engine must not be started until the problem has been resolved.
• Store the machine and fuel in such a way that there is no risk that leaking fuel or fumes can cause any damage.
• Check the fuel level before each use and leave space for the fuel to expand, because the heat from the engine and the sun may otherwise cause the fuel to expand and overflow.
• Avoid overfilling. If you spill petrol on the machine, wipe up the spill and wait until it has evaporated before starting the engine. If you spill on your clothing, change your clothing.
• Allow the machine to cool before performing any actions in the engine compartment.

WARNING! The battery contains lead and lead pollutants, chemicals that are considered to cause cancer, birth defects or other reproductive impairment. Wash your hands after touching the battery.

• Be especially careful when handling battery acid. Acid on the skin can cause serious corrosive injuries. In the event of spillage on the skin wash immediately with water.
• Acid in the eyes can cause blindness, contact a doctor immediately.
  Take care with battery maintenance. Explosive gases form in the battery. Never perform maintenance on the battery while smoking or in the vicinity of open flames or sparks. This can cause the battery to explode and cause serious injuries.

• Make sure all nuts and bolts are tightened correctly and that the equipment is in good condition.
• Do not modify safety equipment. Check regularly to be sure it works properly. The machine must not be driven if protective plates, protective covers, safety switches or other protective devices are not fitted or are defective.
• Observe the risk of injury caused by moving or hot parts if the engine is started with the engine cover open or protective cowlings removed.
• Do not change the setting of governors and avoid running the engine at excessively high revs. If you run too fast, you risk damaging the machine components.
• Never use the machine indoors or in spaces lacking proper ventilation. Exhaust fumes contain carbon monoxide, an odourless, poisonous and highly dangerous gas.

• Stop and inspect the equipment if you run over or into anything. If necessary, make repairs before starting.
• Never make adjustments with the engine running.
• The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer.
• The blades are sharp and can cause cuts. Wrap the blades or wear protective gloves when handling them.
• Check regularly that the parking brake works. Adjust and maintain as required.
• Reduce the risk of fire by removing grass, leaves and other debris that may have fastened on the machine. Allow the machine to cool before putting it in storage.

Transport

IMPORTANT INFORMATION

The parking brake is not sufficient to lock the machine during transport. Ensure you secure the machine firmly to the transporting vehicle.

• The machine is heavy and can cause serious crush injuries. Take extra care when loading it onto or off a vehicle or trailer.

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.

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:

1 Press down the parking brake pedal (1).
2 Press in the lock button (2) on the steering column.
3 Release 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-plugin, finely chops the cuttings to fertiliser. Without the BioClip-plugin 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 fill the tank completely, leave an expansion area of at least 2.5cm (1).

WARNING! Petrol is highly inflammable. 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.

Pull the controls to the end positions, do not use an intermediate position.

Release lever Rider 175

Pull out the control to disengage the drive system.
- Push in the control to engage to the drive system.

• Front control (pushed in), drive system engaged.

Before starting

• Read the safety instructions and information concerning the placement of controls and functions before starting.
• Perform daily maintenance before starting as set out in the Maintenance schedule.

IMPORTANT INFORMATION

The air intake grille in the engine cover behind the driver's seat must not be blocked by, for example, clothing, leaves, grass or dirt. Impaired cooling of the engine.

Risk of major engine damage.

Start the engine

1 Make sure that the clutch control is depressed. Rider 175 AWD has one control for the front axle and one control for the rear axle.

2 Lift 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

3 Move 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.

4 Turn the ignition key to the start position.

5 When 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.

6 Push 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.

7 Set 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 flames 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 INFORMATION Your 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

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

2 Carefully 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.

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

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

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

IMPORTANT INFORMATION

The life span of the drive belts is increased significantly if the engine runs at a low speed when the blades are engaged. Therefore apply full throttle first 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 fixed 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.

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

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

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

Release lever

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

Pull the controls to the end positions, do not use an intermediate position.

WARNING! No service procedures must be conducted on the engine or cutting unit unless:

The engine is switched off.

The parking brake is applied.

The ignition key is removed.

The cutting unit is disengaged.

The ignition cables are removed from the plugs.

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.

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.

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 fill 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^ (40 ^ )

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 first 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 first.

1 Place a container underneath the engine's left oil drain plug.
2 Remove the dipstick. Remove the drain plug from the engine's left side.

3 Let the oil run out into the container.
4 Fit the drain plug and tighten it.
5 If necessary fill 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 filling instructions. The engine holds 1.4 litres (1.5 USqt) when the oil filter is not replaced and 1.6 litres (1.7 USqt) of oil when the oil filter is replaced.
6 Run 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 filter

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

Lightly lubricate the rubber seal on the new oil filter using new oil. Fit the oil filter 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 filter.

Checking the transmission oil level

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

2 Check 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 filter 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 flames, sparks or pilot flames in boilers, hot water heaters, drying cabinets, etc. Exercise caution when handling fuel. It is highly inflammable, 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 flames. Never use petrol for cleaning purposes. Use degreasing agents and hot water instead.

To prepare the machine for storage follow these instructions:

1 Carefully clean the machine, especially under the cutting unit. Touch-up paint damage to avoid rust.
2 Inspect the machine for worn or damaged parts and tighten loose screws and nuts.
3 Change the engine oil, and take care of the waste oil.
4 Empty the fuel tank. Start the engine and run it until the carburettor is emptied of fuel.
5 Remove 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.
6 Grease all grease nipples, joints and axles.
7 Remove the battery. Clean it, charge it, and store it in a cool place.
8 Store 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.
