Motion 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.
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.

Gasoline fuel tank
8065-007
WARNING!
Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see the safety instruction).
WARNING!
The engine and the exhaust system become very hot during operation.
Risk for burns if touched.
Allow engine and exhaust system to cool at least two (2) minutes before refueling
WARNING!
Fill to bottom of filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.
IMPORTANT INFORMATION
Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage Instructions for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur.

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.
Steering
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.
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 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, the mower turns to the direction of the reverse position lever.
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 Manual
Transport in the
Operation section) to an open, flat area, without other people or vehicles or obstacles nearby. To move unit under its own power, the operator must be in the seat, start engine (see
Before Starting in the
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

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 and that the deck is cleaned more often.
Mowing pattern
WARNING!
Clear the lawn of stones and other objects that can be thrown out by the blades.

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.

Transaxle (Transmission) Fluid Change
This transaxle is designed with an external filter for ease of maintenance. To ensure constant fluid quality levels and longer life, an oil filter change interval of every 200 hours is recommended.
The following procedure is performed with the transaxles installed in the mower and the mower on level ground. Apply the pump release valve for each transaxle and set the parking brake.
1. Remove the three ¼" filter guard screws and filter guard. Clean any loose debris from around the perimeter of the filter. See illustration.
2. Place an oil drain pan (12" or more diameter and
8 qt. capacity is optimal) beneath the oil filter.
Remove the oil filter from the transaxle.
10. Fill with 20W50 motor oil until oil just appears at the bottom of each transaxles’ top port
(approximately 2 quarts per transaxle, 4 quarts total). Install the top port lug into each transaxle as the oil level reaches the port.
11. Install and torque the top port plugs to 180 in./lbs.
12. Continue to fill the transaxles through the expansion tank until the “Full Cold” line is reached
(this will take approximately 23 additional ounces).
13. Reinstall the expansion tank cap by hand. Be careful to not overtighten.
14. Proceed to the purge procedure.
Drain old oil filters of all free-flowing oil prior to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area.

After the oil has drained, wipe the filter base surface and apply a film of new oil to the gasket of the replacement filter.
Install the new filter by hand, turning it threequarters to one full turn after the filter gasket contacts the filter base surface.
Reinstall the filter guard. Torque screws to
65 in/lbs. each.
Repeat steps on the opposite side.
Drain old oil filters of all free flowing oil prior to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area.
Remove the top port plug (see illustration) from the left side and right side of the transaxles prior to filling with oil. This will allow the transaxles to vent during oil fill.
Remove the cap from the transaxles’ expansion tank located on the vehicle frame.

Purging Procedures
Due to the effects air has on efficiency in hydrostatic drive applications, it is critical to purge 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.
Resulting symptoms in hydrostatic systems may be:
•
•
Noisy operation.
Lack of power or drive after short term operation.
•
•
High operation temperature and excessive expansion of oil.
Shortened component life.
Before starting, make sure the oil tank is at the proper oil level. If not, fill to the specifications outlined above.
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.
4.
5.
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.
It may be necessary to repeat Steps 2 and 3 until all the air is completely purged from the system. When the hydraulic drive operates at normal noise levels and moves smoothly forward and reverse at normal speeds, the hydraulic drive is considered purged.
After the vehicle has been used two times, the oil level should be checked while the oil is cold and adjusted accordingly.

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 a stabilizer has been added.
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.
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.
3.
4.
5.
6.
7.
Inspect the machine for worn or damaged parts and tighten any nuts or screws that may have become loose.
Change the engine oil; dispose of properly.
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.
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.
Lubricate all grease zerks, joints, and axles.
8.
Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold.
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 the machine performs its best the following season.
