CONTROLS

1. Parking Brake

IMPORTANT INFORMATION The machine must stand absolutely still

when applying the parking brake. Always set the parking brake before dismounting. Release the parking brake before moving the mower.

The parking brake is found on the left of the machine. Pull the lever backward to activate the brake and forward to release it.

2. Steering Control Levers

The machine’s speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or backward about a neutral position. Furthermore, there is a neutral position, which is locked if the steering controls are moved outward. When both controls are in the neutral position (N), the machine stands still. By moving both controls an equal amount forward or backward, the machine moves in a straight line forward or backward respectively. In order, for example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right. Zero turn can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position. The rotation direction when zero turning is determined by which steering control is moved backward behind the neutral position. If the left steering control is pulled backward, the machine turns to the left. Use extra care when using this maneuver. If the steering controls are in uneven positions when standing still or do not fit in the slots for moving the controls outward, they can be adjusted.

OPERATION

Operation

Read “Safety Instructions” section and following pages, if you are unfamiliar with the machine.

Training

Zero turn mowers are far more maneuverable than typical riding mowers due to their unique steering capabilities. We suggest that this section be reviewed in its entirety prior to attempting to move the mower under its own power.

Additionally, we suggest when first operating the mower, use a reduced throttle speed and reduced ground speed by NOT moving control levers to the furthest forward or reverse positions during initial operation, or until operator becomes comfortable with controls. We also suggest first time users, or new users to Zero Turn mowers to become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to attempting to operate on turf. Until operator becomes comfortable with mower controls and zero turning capability, they may damage turf due to overly aggressive maneuvers.

To move forward and backward

The direction and speed of the mower’s movements is effected by the movement of the control lever(s) on each side of mower. The left control lever controls the left wheel. The right control lever controls the right wheel.

IMPORTANT INFORMATION When control levers are in the reverse

position they return to neutral when released. This may cause the mower to suddenly stop.

First time users should push mower (see “Moving by Hand” in the “Operation” section) to an open, flat area, without other people or vehicles/obstacles nearby. In order to move unit under its own power, the operator must be in the seat, start engine (see “Before Starting” in “Operation” section), adjust engine speed to idle, disengage parking brake, do not engage blades at this time, rotate control levers inward. As long as the control levers have not been moved forward or backwards, mower will not move. Slowly move both control levers forward slightly. This will allow mower to start moving forward in a straight line. Pull back on control levers to the neutral position and mower should stop moving. Pull back slightly on control levers, this will allow mower to start moving backwards. Push forward on control levers to the neutral position and mower should stop moving.

To turn to the right

While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction.

To turn to the left

While moving in a forward direction pull the left lever back towards the neutral position while maintaining the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction.

To zero turn

While moving in a forward direction, first pull both control levers back until the mower stops or slows dramatically. Then by alternating one lever slightly to the forward position and the other in the reverse position.

OPERATION

To start an engine with a weak battery

WARNING! Lead-acid batteries generate

explosive gases. Keep sparks, flame and smoking materials away from batteries. Always wear eye protection then around batteries.

If your battery is too weak to start the engine, it should be recharged. (See “Battery” in the Maintenance Section.)

IMPORTANT INFORMATION Your mower is equipped with a 12-volt

negative grounded system. The other vehicle must also be a 12-volt negative grounded system. Do not use your mower to start other vehicles.

If “jumper cables” are used for emergency starting, follow this procedure:

To attach jumper cables

• Connect each end of the RED cable to the POSITIVE (+) terminal on each battery, taking care not to short against chassis.

• Connect one end of the BLACK cable to the NEGATIVE (-) terminal of the fully charged battery.

• Connect the other end of the BLACK cable to a good CHASSIS GROUND on the mower with the discharged battery, away from the fuel tank and battery.

To remove cables, reverse order

• Remove BLACK cable first from chassis and

then from the fully charged battery.

• Remove RED cable last from both batteries.

OPERATION

Mowing Tips

• Observe and flag rocks and other fixed objects to avoid collisions.

• Begin with a high cutting height and reduce it until the desired mowing result is attained. The average lawn should be cut to 2½" (64 mm) during the cool season and over 3" (76 mm) during the hot months. For healthier and better looking lawns, mow often after moderate growth. For best cutting performance, grass over 6" (15 cm) in height should be mowed twice. Make the first cut relatively high; the second to the desired height.

• The mowing result will be best with a high engine speed (the blades rotate rapidly) and low speed (the rider moves slowly). If the grass is not too long and dense, the driving speed can be increased without negatively affecting the mowing result.

• The finest lawns are obtained by mowing often. The lawn becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results.

• Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and the grass clippings fasten under the cowling.

• Hose the mower deck underside with water after each use. When cleaning, the mower deck shall be raised into the transport position. Make sure the mower is cooled and the engine is off.

• Use compressed air to clean top surface of the deck. Avoid flooding water on top surface, engine and electrical components.

• When the mulching kit is used, it is important that the mowing interval is frequent.

WARNING! Clear the lawn of stones and

other objects that can be thrown out by the blades.

Adjusting the Mower Deck

WARNING! Before performing any service or adjustment checklist:

1. Engage the parking brake.

2. Place the Blade switch in the disengaged position.

3. Turn ignition switch to “OFF” position and remove the key.

4. Make sure the blades and all moving parts have completely stopped.

5. Disconnect the spark plug wire from all spark plugs and place the wire where it cannot come in contact with the plug.

Check the tire pressure before adjustment of the mover deck, refer to page 44.

Faulty mower deck adjustment will cause uneven mowing result.

Leveling

1. Position the mower on a level, preferably concrete, surface.

2. Check the pressure in all four tires. See “ Technical Data” on page 66" on page .

3. Raise the mower on lengths of 2" x 4" placed edgewise under the cutting deck from front to rear (see diagram).

4. Lower the deck onto the 2" x 4"´s. The rear of the deck is approximately 1/4" deeper than the front. This gives the deck a proper pitch front to back when lowered onto the 2" x 4" guides.

5. Set cutting height to 4".

6. Adjust the four lower chain bolts so that they are centered in the oblong slots.

7. Move the lifting lever and check that all the chains are equally tensioned. If they are not, adjust the appropriate lower chain bolt in its slot.

WARNING! Blades are sharp. Protect your

hands with gloves and/or wrap blades with a heavy cloth when handling.

Adjusting Cutting Height

1. Raise and secure the deck height lever to the transport position (4 1/2").

2. Position blade tip so it is straight forward.

3. Measure from the cutting edge of the blades to a flat level surface. The distance should be 4 1/2" (114 mm).

4. Drop and secure the lever at (for example) the 2" cutting height. Measure as above. The distance should be 2" (50 mm).

General

Remove the ignition key to prevent unintentional movements during lubrication. When lubricating with an oil can, it must be filled with engine oil. When lubricating with grease, unless otherwise stated, use a high grade molybdenum disulfide grease. For daily use, the machine should be lubricated twice weekly. Wipe away excess grease after lubrication.

It is important to avoid getting lubricant on the belts or the drive surfaces on the belt pulleys. Should this happen, attempt to clean them with spirits. If the belt continues to slip after cleaning, it must be replaced. Gasoline or other

petroleum products must not be used to clean belts.

English-55

LUBRICATION

Lubricating the Cables

If possible, grease both ends of the cables and move the controls to end stop positions when lubricating. Refit the rubber covers on the cables after lubrication. Cables with sheaths will bind if they are not lubricated regularly. If a cable binds, it can disrupt operation.

If a cable binds, remove the cable and hang it vertically. Lubricate it with light engine oil until the oil begins to escape from the bottom.

Tip: Fill a small plastic bag with oil and tape it so that it seals against the sheath and allow the cable to hang vertically from the bag overnight. If you do not succeed in lubricating the cable, it must be replaced.

Lubricating in Accordance with the Lubrication Schedule

1. Front Wheel Mount

Lubricate with a grease gun, one zerk for each wheel mount, until the grease is forced out.

Use only good quality bearing grease. Grease from well-known brand names (petrochemical

companies, etc.) usually maintains a good quality.

2. Front Wheel Bearings

Lubricate with a grease gun, one zerk for each set of wheel bearings, until the grease is forced out.

Use only good quality bearing grease.

3. Deck spindle

Lower the cutting deck completely. If you use grease gun without rubber hose, the foot

plate must be removed. Lubricate with a grease gun, one zerk, 2-3 strokes. Use only good quality bearing grease.

Purging Procedures

Due to the effects air has on efficiency in hydrostatic drive applications, it is critical that it is purged from the system.

These purge procedures should be implemented any time a hydrostatic system has been opened to facilitate maintenance or any additional oil has been added to the system.

The resulting symptoms in hydrostatic systems may be:

1. Noisy operation.

2. Lack of power or drive after short term operation.

3. High operation temperature and excessive expansion of oil.

Before starting, make sure the transaxle is at the proper oil level. If it is not, fill to the specifications outlined earlier.

The following procedures are best performed with the vehicle drive wheels off the ground. Then repeated under normal operating conditions.

1. Disengage the brake if activated.

2. With the bypass valve open and the engine running at fast idle, slowly move the directional control in both forward and reverse directions (5 or 6 times). As air is purged from the unit, the oil level will drop.

3. With the bypass valve closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level, and add oil as required after stopping the engine.

4. It may be necessary to repeat Steps 2 and 3 until all the air is completely purged from the system. When the transaxle operates at normal noise levels and moves smoothly forward and reverse at tnormal speeds, then the transaxle is considered purged.

5. After the vehicle has been used two times, the oil level should be checked while the oil is cold and adjusted accordingly.

STORAGE

Storage

Winter Storage

At the end of the mowing season, the machine should be readied for storage (or if it will not be in use for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function.

Fuel stabilizers are an acceptable option as regards to the sticky residues that can occur during storage.

Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer. Run the engine for at least 10 minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if you have added stabilizer

WARNING! Never store an engine with fuel

in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water tank, clothes drier, etc. Handle the fuel with care. It is very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and far away from open flame. Never use gasoline for cleaning. Use a degreaser and warm water instead.

To ready the machine for storage, follow these steps:

1. Thoroughly clean the machine, especially under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion.

2. Inspect the machine for worn or damaged parts and tighten any nuts or screws that may have become loose.

3. Change the engine oil; dispose of properly.

4. Empty the fuel tanks or add a fuel stabilizer. Start the engine and allow it to run until the carburetor is drained of fuel or the stabilizer has reached the carburetor.

5. Remove the spark plug and pour about a tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plug.

6. Lubricate all grease zerks, joints, and axles.

7. Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold.

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

Service

When ordering spare parts, please specify the purchase year, model, type, and serial number.

Always use genuine Husqvarna spare parts. An annual check-up at an authorized service

workshop is a good way to ensure that your machine performs its best the following season.
