SAFETY INFORMATION

Read This Manual Carefully And Thoroughly Before Operating The Mower!

Training

1. Carefully and thoroughly read the owner’s manual. Allow adequate time to fully understand the controls and operation of the equipment.

2. Never allow anyone to operate the mower that is not old enough, large enough, and strong enough to safely handle the machine. and that has not read and fully understood the owner’s manual.

3. Do not carry passengers. Avoid mowing while people, especially children and pets are nearby, since rotating blades can throw rocks and other items with enough force to cause serious injury.

Before Use of Equipment

Operator:

Wear protective clothing while mowing. Long trousers and safety glasses will help reduce the risk of injury from thrown objects. It is required that steel toe shoes with aggressive soles or some other type of substantial footwear be worn to help protect your feet and maintain traction on slopes or uneven ground. Always wear hearing protection while mower is in operation or engine is running.

Mowing Area:

Thoroughly inspect the area where the equipment is to be used. Look for items such as stones, sticks, wire and other foreign objects. When struck by the mower, these and other objects may become projectiles that could lead to serous injury and/or death.

Mower:

For your safety and the long life of your mower, always inspect the mower before each use. Before inspection, make sure it is on a flat and level surface, the blades are disengaged, the ignition switch off with the key removed, and the spark plug wire is off of the spark plug(s) and hidden so that accidental contact can not be made.

General Condition:

· Walk around the mower looking for any fluid spills or leaks on or underneath the mower. Remove any

and all excessive debris, dirt, and/or fluids.

· Look for signs of damage or excessive wear. Check the tightness of all nuts, bolts, pins, and screws.

Tighten any that may be loose and replace any that may have been lost during use.

· Be sure the safety interlock controls are operating properly so that the engine can not be started unless

the ground speed control lever is in neutral and the blades disengaged.

Check the mower blades for any damage or abnormal wear and replace in sets so that they are balanced.

· Check the mower cutting height to assure a high quality and even cut. See page 13 for details.

· Check the tire pressure on all four tires. See page 16 for details.

· Check all belts for proper wear and correct tension. See pages 18-20 for details.

· Check engine oil and air filters as recommended in the engine manufacturers’ operators manual.

· Properly secure your mower for transport. The parking brake should not be engaged during transport.

Operation of Equipment

DANGER: GASOLINE IS HIGHLY FLAMMABLE AND EXPLOSIVE. DO NOT ADD FUEL WHILE THE ENGINE IS RUNNING OR IS HOT. KEEP OPEN FLAMES, SPARKS, AND HEAT AWAY FROM THE FUEL AND STORE FUEL IN CONTAINERS SPECIFICALLY DESIGNED FOR THAT PURPOSE. ADD FUEL OUTDOORS ONLY AND IF THE FUEL IS SPILLED, DO NOT START THE ENGINE. MANUALLY PUSH THE MOWER AWAY FROM THE SPILL AND IMMEDIATELY WIPE UP.

Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. Carbon monoxide is odorless, tasteless, and can be fatal.

Mow only in daylight.

Make sure the mower is in neutral and the blades are disengaged before attempting to start the engine.

Do not stop or start suddenly when going uphill. Never use riding attachments on slopes since there is an increase risk that they might roll over.

Avoid steep slopes and use extreme caution when changing directions or speed when operating on a slope.

Be extremely careful when operating on a slope or when the grass is damp or wet. Reduced traction could cause sliding. Never mow by pulling the mower back towards you...you might slip.

Watch for traffic when crossing surfaces other than grass. (i.e. transporting,) loading a trailer or vehicle, or when the mower is not in use.

Never operate the mower with defective guards, shields, or without the safety devices securely mounted in place.

Never direct discharge of material toward bystanders nor allow anyone near the mower while in operation.

Do not change the governor settings or over speed the engine.

Always stop the engine whenever you leave the mower, even for a moment.

To help reduce the risk of a fire hazard, keep the engine and the area around the engine free of grass, leaves, or any other type of foreign material.

Beware of cutting edges. Always wear gloves for safety when performing blade maintenance activities. Beware on multiple blades units since the rotation of one blade may cause the rotation of the other blades.

Do not store or operate the mower with the grass chute deflector in raised position. Serious injury could occur.

Keep body and hands away from pin holes or nozzles that eject hydraulic fluids since fluid escaping under pressure may have sufficient force to penetrate skin and cause serious injury. If foreign fluid is injected under the skin, it must be surgically removed within a few hours by a doctor familiar with this form of injury. Always use paper or cardboard and not your hands to search for leaks.

SAFETY INFORMATION DECALS

The following labels are intended to alert you to potential hazards and to provide you with important safety information. Should these decals become difficult to read or are missing from the mower, contact your mower dealer for a replacement.

OPERATING THE MOWER

It is recommended that before you operate the mower, you allow adequate time to fully understand the controls and operation of the equipment. When reading this manual, it is recommended that you do so with the equipment nearby for quick orientation, reference of controls and maintenance adjustments.

Operating Controls

Before continuing to read the manual, it is recommended that you take adequate time to identify the controls of the mower.

“A” Traction Control “E” Throttle/Choke Control “B” Operator Presence Controls “F” Travel Speed Control Lever “C” Blade Control Lever “G” Neutral Lever “D” Key Switch “H” Parking Brake Lever

Starting The Engine:

DANGER: DO NOT OPERATE THE ENGINE IN A CONFINED SPACE WHERE DANGEROUS CARBON MONOXIDE FUMES CAN COLLECT. CARBON DIOXIDE IS ODORLESS, TASTELESS, AND CAN BE FATAL.

After going through the steps as discussed on pages 6-9, you are now ready to start the engine. NOTE: THIS UNIT WAS SHIPPED WITHOUT GAS, BE SURE TO ADD FRESH GAS AND TO DOUBLE CHECK THE OIL IN THE ENGINE BEFORE ATTEMPTING TO START THE MOWER.

1. Make sure that the shut off valve, located at the bottom of the fuel tank is in the “ON” position (figure 2).

2. Make sure that the traction control lever is in the neutral position (figure 3)

3. Make sure that the parking brake lever is in “OFF” position. (figure 4)

4. Make sure that the neutral lever is in position. (figure 5)

5. Make sure that the speed control lever is in the position and the blade control lever is in the “OFF” position. NOTE: The safety interlock system will prevent the engine from being started if the speed control is not in the position and the blade control lever is not in the “OFF” position.

6. Slide the engine control to the position, or to “CHOKE” if the engine is cold.

7. Turn the key clockwise to the “RUN” position.

8. Slowly pull the start cord on the engine until just past compression. STOP! Return the start cord and then pull firmly with a smooth, steady motion to start the engine.

9. When the engine starts to run, slowly return the engine speed control out of “CHOKE” to the desired engine speed.

Going Forward:

CAUTION Become totally familiar with the operation and characteristics of

the mower before attempting to actually mow with it.

1. Making sure that the traction control levers are in the neutral position, push down and hold the operator presence control lever “A” on the handle grips with one hand (figure 6).

2. With the other hand, move the speed control lever to the desired speed. Near position is slow and near position is for transporting the mower between mowing areas. (figure 7) It is recommended that you start out in and then increase your ground speed to match the mowing conditions.

3. Release the traction control lever locks by squeezing up both traction control levers “C” only as much as needed while at the same time applying forward pressure in the traction control lever locks “B” with your thumbs.

4. Slowly and evenly, let both traction control levers down simultaneously and the mower will start to go forward. NOTE: If the operator lets go of both operator presence control levers while either the blade control lever is in “ON”, and/or the gear shift control lever is out of the neutral position the safety inter lock system will stop the engine. To restart the mower, reset all controls to the “OFF” position and neutral “N” positions.

NOTE: Top speed is suggested only for transport!

Turning The Mower

To turn the mower in the direction you want to go, gently squeeze the side’s traction control lever (i.e. to go right, squeeze the right traction control lever; to go left, squeeze the left traction control lever). The more a particular traction control lever is squeezed, the sharper a turn the mower will make.

Stopping The Mower

To stop the mower, gently and evenly squeeze up on both of the traction control levers until the mower comes to a complete stop. Then with your thumbs, push down on the traction lever locks until the levers are securely locked in the neutral position. While still holding down with one hand the operator presence controls, move the speed control lever to the position with the other hand. If the operator is leaving the operator’s position behind the mower for any reason, disengage the blades, shut the engine off, and remove the key.

If you are leaving the operator’s position, park the mower on level ground. If it is not possible to do so, be sure to block the wheels to prevent the mower from rolling away.

Using The Reverse

1. Slowly and evenly squeeze up on both control levers until the mower comes to a complete stop and then with your thumbs, push down on the traction lever locks until the levers are securely locked in the neutral position.

2. While still holding down the operator presence control with one hand, use the other and pull the blade control lever to the “OFF” position.

3. Move the speed control lever to the position.

4. Slowly and evenly, squeeze up on both control levers only as much as needed, while at the same time the mower will go backwards. The farther both control levers are squeezed, the faster the mower will go in reverse. NOTE: When going in reverse you should look down and behind. .

5. To stop the mower, slowly and evenly let both traction control levers down simultaneously until the mower comes to a complete stop.

Mowing

DANGER: THOROUGHLY INSPECT THE AREA WHERE THE EQUIPMENT IS TO BE USED. LOOK FOR ITEMS SUCH AS STONES, STICKS, WIRE, AND OTHER FOREIGN OBJECTS. WHEN STRUCK BY THE MOWER, THESE AND OTHER OBJECTS MAY BECOME PROJECTILES THAT COULD LEAD TO SERIOUS INJURY AND OR DEATH. CLEAR AREA OF ALL DEBRIS AND KEEP PEOPLE AND PETS AWAY.

DANGER: DO NOT OPERATE THE MOWER WITH DEFECTIVE GUARDS, SHIELDS, OR WITHOUT THE SAFETY DEVICES SECURELY IN PLACE.

For the highest quality of cut and performance, always mow with the engine at full throttle. Quality of cut may be determined by the ground speed and speed of the mower. Generally, the slower the mower travels across the terrain, the better the cut.

1. With the mower at the beginning of the area to be mowed and traction control levers in the neutral position, hold down with one hand the operator presence control.

2. With the other hand, slowly push the blade control lever forward to the “ON” position.

3. Move the speed control lever to the desired speed. Always begin at a slow ground speed and increase only as the condition of the terrain warrants.

4. Slowly and evenly, engage the traction control levers and begin mowing.

5. To stop mowing, slowly and evenly squeeze up on both traction control levers until the mower comes to a complete stop and then with your thumbs, push down on the traction lever locks until the levers are securely locked in the neutral position. Return the speed control lever to the position.

6. Pull the blade control lever back to the “OFF” position.

Moving the Mower Without Turning on the Engine

1. Push the parking lever to the “ON” position.

2. Move the neutral lever to the position (figure 8)

3. Push the parking lever to the “OFF” position. You can now move the mower.

4. Before starting to move the mower, make sure the hydro transmission is completely closed.

Parking the Mower

Push the parking lever to the “ON” position. (figure 9) Do not transport the mower with the parking brake engaged. Secure the mower properly when transporting the mower.

CAUTION: Gently engage the breaking mechanism; Excessive force may cause damage.

WARNING: IF YOU ARE NOT FAMILIAR WITH THE OPERATION OF THE HYDRO DRIVE AND ZERO TURN FEATURE, PRACTICE TURNING AND MANEUVERING WITH THE HAND CONTROLS BEFORE ENGAGING THE BLADE.

Changing The Height Of Cut:

DANGER: BEFORE MAKING ANY ADJUSTMENTS AND/OR SERVICING YOUR MOWER, MAKE SURE THE MOWER IS ON LEVEL GROUND, BLADES DISENGAGED, KEYS REMOVED, AND THE ENGINE OFF WITH THE SPARK PLUG WIRE(S) REMOVED FROM THE SPARK PLUGS(S) AND HIDDEN TO PREVENT ACCIDENTAL CONTACT.

When your hydro mower is shipped from the factory, the mowing height is set at 2-1/2”. The mowing height may be raised or lowered using a combination of front wheel spacers and blade bolt assembly spacers. It is recommended that you first set your height of cut to the highest level using the blade spacers and then lower the height of cut using the front wheel spacers.

Measuring The Height Of Cut:

CAUTION Beware of the cutting edges on the blades. The rotation of one blade may cause the other

blade(s) to rotate. Always wear work gloves when handling blades.

Park the mower on level ground.

With the blade control lever in the “OFF” position, the engine off with the key removed, and the spark plug wire (s) removed from the spark plug(s), reach through the discharge chute and slowly rotate the blade

so that the length of the blade is going from the front of the mower towards the rear.

Using a tape measure or small ruler, measure the distance from the front tip of the blade’s cutting edge to the ground. As a general rule, if measuring the cutting height on a hard surface such as concrete, the mower will usually mow about 1/4” lower in grass due to the weight of the machine.

Removing And Adjusting The Blades:

CAUTION Beware of the cutting edges on the blades. The rotation of one blade may cause the other

blade(s) to rotate. Always wear work gloves when handling blades.

Park the mower on level ground and block the rear wheels to prevent accidental rollback. Raise the front end of the mower and secure with a jackstand. Using two (2) 15/16” box end wrenches, use one wrench to loosen nut “A” while holding blade bolt “C” with the

other wrench (Figure 10). Slide the blade bolt down through the mower deck and out. To raise the blades to the height desired, remove the appropriate amount of spacers from the blade bolt.

Example: If the height of cut needs to be raised 1/2”, move two (2) of the 1/4” spacers “B” on each blade from underneath the mower (Figure 10) to the top of the mower (Figure 11).

Reinsert the blade bolt through the cutting deck. Install the blade spacers that were removed, back onto the blade bolt followed by the nut and tighten (Figure 6).

IMPORTANT: The amount of spacers should always be the same on each blade bolt. Never put the spacers below the blade.

Adjusting The Front Wheels: (refer to Figure 12)

Raise and support the front of the mower with a jackstand. While supporting the front wheel with one hand, remove the flip pin from the wheel shaft. Remove the wheel from the front wheel support arm being careful not to loose the spacers. Remove the amount of spacers desired to lower the height of cut. Reinsert the wheel through the support arm. Reinstall the spacers on the top that were removed from the bottom and then secure with the flip pin. To raise the height, repeat steps 1-3, but take the spacers from the top of the wheel support arm, and put them on the bottom.

Figure 10

Figure 11

Figure 12

Figure 13

Adjusting the Deck: (refer to Figure 13)

Changes to the cutting height can be achieved by repositioning the cutter deck. There are six available positions. This adjustment will also effect the pitch of the deck. NOTE: Pitch is the angle of the blades (comparing front to rear). A 1/4” downward pitch (front of deck down) recommended for best cutting performance.
