CONTROLS
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. There is also 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.

Training
Due to unique steering capabilities, zero turn mowers are far more maneuverable than typical riding mowers.
This section should be reviewed in its entirety prior to attempting to move the mower under its own power.
When first operating the mower or until becoming comfortable with controls, use a reduced throttle speed and reduced ground speed. DO NOT move control levers to the furthest forward or reverse positions during initial operation.
First time users should become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to attempting to operate on turf. Until the operator becomes comfortable with the mower controls and zero turning capability, overly aggressive maneuvers may damage turf.
Steering
To move forward and backward
The direction and speed of the mower’s movements are 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.
First time users should push the mower (see Moving
Machine By Hand in the Operation section) to an open, flat area without other people, vehicles or obstacles nearby. To move the unit under its own power, the operator must sit in the seat and start the engine (see Before Starting in the Operation section). Adjust the engine speed to idle, disengage the parking brake but do not engage the blades at this time. Rotate control levers inward. As long as the control levers have not been moved forward or backwards, the mower will not move.
Slowly move both control levers forward slightly. This will allow mower to start moving forward in a straight line. Pull the control levers back to the neutral position and the mower should stop moving.
Pull back slightly on control levers, allowing the mower to move backwards. Push the control levers forward 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, complete the turn.
IMPORTANT INFORMATION
When control levers are in the reverse position they return to neutral when released. This may cause the mower to suddenly stop.

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.
Mowing pattern
WARNING!
Clear the lawn of stones and other objects that can be thrown out by the blades.
8011-603
WARNING!
Never drive the rider on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side.
Avoid sudden directional changes.

STORAGE
Winter Storage
The machine should be readied for storage at the end of the mowing season, 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 store 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.
