Safety Rules & Information

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.

This mowing deck is capable of amputating hands and feet and throwing objects.

The triangle in text signifies important cautions or warnings which must be followed.

GENERAL OPERATION

• Read, understand, and follow all instructions in the manual and on the unit before starting.

• Only allow responsible adults, who are familiar with the instructions, to operate the unit (local regulations can restrict operator age).

• Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade(s).

• Be sure the area is clear of other people before mowing. Stop unit if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Always look down and behind before and while travelling in reverse.

• Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the deflector in place.

• Slow down before turning.

• Never leave a running unit unattended. Always disengage the

PTO, set parking brake, stop engine, and remove keys before dismounting.

• Turn off the PTO switch to disengage the blades when not mowing.

• Stop engine before removing grass catcher or unclogging chute.

• Mow only in daylight or good artificial light.

• Do not operate the unit while under the influence of alcohol or drugs.

• Watch for traffic when operating near or crossing roadways.

• Use extra care when loading or unloading the unit into a trailer or truck.

• Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-related injuries.

These operators should evaluate their ability to operate the riding mower safely enough to protect themselves and others from injury.

• Keep in mind the operator is responsible for accidents occurring to other people or property.

• All drivers should seek and obtain professional and practical instruction.

• Always wear substantial footwear and trousers. Never operate when barefoot or wearing sandals.

• Before using, always visually check that the blades and blade hardware are present, in-tact, and secure. Replace worn or damaged parts.

• Never operate the machine with defective guards, or without safety protective devises in place.

• Disengage attachments before: refuelling, removing an attachment, making adjustments (unless the adjustment can be made from the operator’s position).

• When the machine is parked, stored, or left unattended, lower the cutting means unless a positive mechanical lock is used.

• Follow the manufacturer’s recommendation for wheel weights or counterweights.

SLOPE OPERATION

WARNING

Never operate on slopes greater than 17.6 percent

(10°) which is a rise of 3-1/2 feet (106 cm) vertically in

20 feet (607 cm) horizontally.

When operating on slopes use additional wheel weights or counterweights. See your dealer to determine which weights are available and appropriate for your unit.

Select slow ground speed before driving onto slope.

In addition to front and rear weights, use extra caution when operating on slopes with rear-mounted grass catcher.

Mow UP and DOWN the slope, never across the face, use caution when changing directions and DO

NOT START OR STOP ON SLOPE.

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution.

If you cannot back up the slope or if you feel uneasy on it, do not operate on it.

Control of a ride-on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are: insufficient tire grip on the ground, speed too fast, inadequate braking, the type of machine is unsuitable for it’s task, lack of awareness of the ground conditions, incorrect hitching and load distribution.

Do

• See your authorized dealer for recommendations of wheel weights or counterweights to improve stability.

• Mow up and down slopes, not across.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles.

• Use slow speed. Tires may lose traction on slopes even through the brakes are functioning properly. Choose a low gear so that you will not have to stop or shift while on the slope.

• Use extra care with grass catchers or other attachments. These can change the stability of the unit.

• Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.

• Always keep unit in gear especially when traveling downhill. When clutching, release clutch slowly.

Do Not

• Do not start or stop on a slope. If tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.

• Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

• Do not mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.

• Do not mow on wet grass. Reduced traction could cause sliding.

• Do not try to stabilize the unit by putting your foot on the ground.

• Do not use grass catchers on steep slopes.

• Do not mow slopes you cannot back up.

• Do not shift to neutral and coast down hill.

Safety Rules

Slope Operation Continued

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the unit and the mowing activity.

Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and under the watchful care of another responsible adult.

• Be alert and turn unit off if children enter the area.

• Before and during reverse operation, look behind and down for small children.

• Never carry children. They may fall off and be seriously injured or interfere with safe unit operation.

• Never allow children to operate the unit.

• Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

TOWING

• Never allow children or others in or on towed equipment.

• Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.

• Follow the manufacturer’s recommendations for weight limit for towed equipment and towing on slopes.

• On slopes, the weight of the towed equipment may cause loss of traction and loss of control.

• Travel slowly and allow extra distance to stop.

• Do not shift to neutral and coast down hill.

TRANSPORTING AND STORAGE

WARNING

When transporting this tractor on an open trailer, make sure unit is facing forward, toward the direction of travel. If tractor is facing backward, wind lift could cause damage to the hood.

• Always observe safe refueling and fuel handling practices when refueling the tractor after transportation or storage.

• Always follow the engine manual instructions for storage preparations before storing the tractor for both short and long term periods.

• Always follow the engine manual instructions for proper start-up procedures when returning the unit to service.

• Never store the unit or fuel container inside where there is an open flame or pilot light, such as in a water heater. Allow unit to cool before storing.

EMISSIONS

• Engine exhaust from this product contains chemicals known, in certain quantities, to cause cancer, birth defects, or other reproductive harm.

• Look for the relevant Emissions Durability Period and Air Index information on the engine emissions label.

SERVICE AND MAINTENANCE

• Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

• Keep unit free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage.

• Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.

• Never make adjustments or repairs with the engine running unless specified otherwise in the engine manufacturer’s manual.

• Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recommended parts, when necessary.

• Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.

• Check brake operation frequently. Adjust and service as required.

• Use only factory authorized replacement parts when making repairs.

• Always comply with factory specifications on all settings and adjustments.

• Only authorized service locations should be utilized for major service and repair requirements.

• Never attempt to make major repairs on this unit unless you have been properly trained. Improper service procedures can result in hazardous operation, equipment damage and voiding of manufacturer’s warranty.

• On multiple blade mowers, take care as rotating one blade can cause other blades to rotate.

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

Operating the engine at excessive speed can increase the hazard of personal injury.

• Disengage drive attachments, stop the engine, remove the key, and disconnect the spark plug wire(s) before: clearing attachment blockages and chutes, performing service work, striking an object, or if the unit vibrates abnormally. After striking an object, inspect the machine for damage and make repairs before restarting and operating the equipment.

CONTROL FUNCTIONS

Please take a moment and familiarize yourself with the name, location, and function of these controls so that you will better understand the safety and operating instructions provided in this manual.

The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section.

A. Ground Speed Control Levers

These levers control the ground speed of the rider. The left lever controls the left rear drive wheel and the right controls the right rear drive wheel.

Moving a lever forward increases the FORWARD speed of the associated wheel, and pulling back on a lever increases the REVERSE speed.

Note: The further a lever is moved away from the neutral position the faster the drive wheel will turn.

B. Top Speed Adjustment Knobs

These knobs independently control the top speed of the left and right drive wheels, and are used to balance the maximum forward lever positions. Turn a knob CLOCK-

WISE to lower the top speed of a wheel, and COUNTER-

CLOCKWISE to increase the top speed of a wheel.

C. Seat Adjustment Lever

The seat can be adjusted forward and back. Move the lever to the LEFT, position the seat as desired, and release the lever to lock the seat in position.

D. Ignition Switch

The ignition switch starts and stops the engine, it has three positions:

OFF Stops the engine and shuts off the electrical system.

RUN Allows the engine to run and powers the electrical system.

START Cranks the engine for starting.

NOTE: Never leave the ignition switch in the RUN position with the engine stopped–this drains the battery.

I & J. Throttle / Choke Control

14HP & 16HP Models have a combined throttle / choke control (I, see Figure 1). Moving the throttle / choke control fully forward chokes the engine for cold starts. (A warm engine may not require choking.) The first “notch” position back from choke position is FULL throttle.

Always operate the unit at FULL throttle.

18HP Models have separate throttle and choke controls

(I & J, see Figure 2). Pulling the round choke control knob (J) out fully chokes the engine for cold starts. (A warm engine may not require choking.) Moving the throttle control (I) fully forward is FULL throttle position.

Always operate the unit at FULL throttle.

K. Headlight Switch

18HP Models Only: Turn the switch ON to light the front headlight.

SAFETY

INTERLOCK SYSTEM

This unit is equipped with safety interlock switches and other safety devices. These safety systems are present for your safety, do not attempt to bypass safety switches, and never tamper with safety devices. Check their operation regularly.

Operational SAFETY Checks

Your unit is equipped with a seat switch safety system. Check the seat switch operation every fall and spring with the following tests.

Test 1 — Engine should NOT crank if any of the following conditions exist:

• PTO switch is engaged (ON), OR

• Clutch/brake pedal is NOT fully depressed.

Test 2 — Engine SHOULD crank if ALL of the following conditions are met:

• PTO switch is NOT engaged, AND

• Clutch/brake pedal IS fully depressed.

Test 3 — Engine should SHUT OFF if any of the following conditions exist:

• Operator rises off seat with transmission control levers out of the neutral gate AND clutch/brake pedal NOT depressed, OR

• Operator rises off seat with clutch/brake pedal

NOT fully depressed, OR

• Operator rises off seat with PTO engaged.

Test 4 — Blade Brake Check

Mower blades and mower drive belt should come to a complete stop within five seconds after electric

PTO switch is turned off (or operator rises off seat).

If mower drive belt does not stop within five seconds, see your dealer.

NOTE: Once the engine has stopped, PTO switch must be turned off after operator returns to the seat in order to start the engine.

WARNING

If the unit does not pass a safety test, do not operate it. See your authorized dealer. Under no circumstance should you attempt to defeat the purpose of the safety interlock system.

DRIVING PRACTICE

The lever controls of the Zero Turn rider are responsive, and learning to gain a smooth and efficient control of the rider’s forward, reverse, and turning movements will take some practice.

Spending some time going through the maneuvers shown and becoming familiar with how the unit accelerates, travels, and steers — before you begin mowing — is absolutely essential to getting the most out of the Zero

Turn rider.

Locate a smooth, flat area of your lawn — one with

plenty of room to maneuver. (Clear the area of objects, people and animals before you begin.) Operate the unit at mid-throttle during this practice session (ALWAYS operate at full throttle when mowing), and turn slowly to prevent tire slippage and damage to your lawn.

We suggest you begin with the Smooth Travel procedure to the right, and then advance through the forward, reverse, and turning maneuvers.

WARNING

Make certain the area of operation, and especially the direction of travel is clear of objects, people and animals.

Always look DOWN AND BEHIND before backing!

BASIC DRIVING

Forward Travel Practice

Gradually move both ground speed control levers — evenly FORWARD from neutral. Slow down and repeat.

NOTE: Straight forward travel takes practice. If necessary, top speed can be balance-adjusted — see the Top

Speed Adjustment Knobs in the Adjustments section near the back of this manual.

Forward

Travel

Reverse Travel Practice

LOOK DOWN & BEHIND, then gradually move both ground speed control levers evenly BACK from neutral.

Slow down and repeat.

NOTE: Practice backing up for several minutes before attempting to do so near objects. The rider turns sharply in reverse as well as forward, and backing up straight takes practice.

Practice Turning Around a Corner

While traveling forward allow one handle to gradually return back toward neutral. Repeat several times.

NOTE: To prevent pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward.

Practice Turning In Place

To turn in place, “Zero Turn,” gradually move one ground speed control lever forward from neutral and one lever back from neutral simultaneously. Repeat several times.

NOTE: Changing the amount each lever is pulled—forward or back, changes the “pivot point” you turn on.

ADVANCED DRIVING

Executing an

End-Of-Row Zero Turn

Your Zero Turn Rider’s unique ability to turn in place allows you to turn around at the end of a cutting row rather than having to stop and Y-turn before starting a new row.

For example, to execute a right end-of row

Zero Turn:

1. Slow down at the end of the row.

2. Move the LEFT ground speed control lever forward slightly while moving the

RIGHT ground speed control lever back to center and then slightly back from center.

3. Begin mowing forward again.

This technique turns the rider RIGHT and slightly overlaps the row just cut — eliminating the need to back up and re-cut missed grass.

STORAGE

Temporary Storage (30 Days Or Less)

Remember, the fuel tank will still contain some gasoline, so never store the unit indoors or in any other area where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the unit in any structure used for human or animal habitation.

Here is a checklist of things to do when storing your unit temporarily or in between uses:

• Keep the unit in an area away from where children may come into contact with it. If there’s any chance of unauthorized use, remove the spark plug (s) and put in a safe place. Be sure the spark plug opening is protected from foreign objects with a suitable cover.

• If the unit can’t be stored on a reasonable level surface, chock the wheels.

• Clean all grass and dirt from the mower.

WARNING

Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion.

Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to your person or property.

Drain fuel into an approved container outdoors away from open flame or sparks.

Long Term Storage (Longer Than 30 Days)

Before you store your unit for the off-season, read the

Maintenance and Storage instructions in the Safety Rules section, then perform the following steps:

1. Drain crankcase oil while engine is hot and refill with a grade of oil that will be required when unit is used again.

2. Prepare the mower deck for storage as follows: a. Remove mower deck from the unit.

b. Clean underside of mower deck.

c. Coat all bare metal surfaces with paint or light coat of oil to prevent rusting.

3. Clean external surfaces and engine.

4. Prepare engine for storage. See engine owner’s manual.

5. Clean any dirt or grass from cylinder head cooling fins, engine housing and air cleaner element.

6. Cover air cleaner and exhaust outlet tightly with plastic or other waterproof material to keep out moisture, dirt and insects.

7. Completely grease and oil unit as outlined in the Normal

Care section.

8. Clean up unit and apply paint or rust preventative to any areas where paint is chipped or damaged.

9. Be sure the battery is filled to the proper level with water and is fully charged. Battery life will be increased if it is removed, put in a cool, dry place and fully charged about once a month. If battery is left in unit, disconnect the negative cable.

10. Drain fuel system completely or add Simplicity gasoline stabilizer to the fuel system. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of ignition and ignite, causing risk of explosion and fire.

NOTE: Gasoline, if permitted to stand unused for extended periods (30 days or more), may develop gummy deposits which can adversely affect the engine carburetor and cause engine malfunction. To avoid this condition, add Simplicity gasoline stabilizer to the fuel tank and run the engine a few minutes, or drain all fuel from the unit before placing it in storage.

STARTING AFTER

LONG TERM STORAGE

Before starting the unit after it has been stored for a long period of time, perform the following steps.

1. Remove any blocks from under the unit.

2. Install the battery if it was removed.

3. Unplug the exhaust outlet and air cleaner.

4. Fill the fuel tank with fresh gasoline. See engine manual for recommendations.

5. See engine owner’s manual and follow all instructions for preparing engine after storage.

6. Check crankcase oil level and add proper oil if necessary. If any condensation has developed during storage, drain crankcase oil and refill.

7. Inflate tires to proper pressure. Check fluid levels.

8. Start the engine and let it run slowly. DO NOT run at high speed immediately after starting. Be sure to run engine only outdoors or in well ventilated area.

• Front: 20 psi (138 kPa) • Rear: 10 psi (69 kPa)

Side to Side Leveling - All Models

1. With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn the front wheels straight forward.

2. Check for bent blades and replace if necessary.

3. Place the mower in high-cut position. Arrange the mower blades so that they are pointing from side-toside (Figure 31).

4. See Figure 32. Measure the distance between the outside tips of each blade and the ground. If there is more than 1/8" (3mm) difference between the measurements on each side, proceed to step 5. If the difference is 1/8" (3mm) or less, proceed to Front TO

Back Leveling.

5. See Figure 32. Loosen the outside nut (A) and taptite screw (C), then turn the eccentric nut (B) to raise or lower the left side of the deck. When the mower deck is level, hold the eccentric nut while tightening the outside nut. Tighten the taptite screw (C).

Measurement should be within 1/8"

BATTERY SERVICE

WARNING

Keep open flames and sparks away from the battery; the gasses coming from it are highly explosive. Ventilate the battery well during charging.

6. Charge the battery until fully charged (until the specific gravity of the electrolyte is 1.250 or higher and the electrolyte temperature is at least 60° F). The best method of making certain a battery is fully charged, but not over charged, is to measure the specific gravity of a cell once per hour. The battery is fully charged when the cells are gassing freely at low charging rate and less than 0.003 change in specific gravity occurs over a three hour period.

Checking Battery Voltage

A voltmeter can be used to determine condition of battery. When engine is off, the voltmeter shows battery voltage, which should be 12 volts. When engine is running, the voltmeter shows voltage of charging circuit which normally is 13 to 14 volts.

A dead battery or one too weak to start the engine may not mean the battery needs to be replaced. For example, it may mean that the alternator is not charging the battery properly. If there is any doubt about the cause of the problem, see your dealer. If you need to replace the battery, follow the steps under Cleaning the Battery &

Cables in the Regular Maintenance Section.

WARNING

Do not attempt to charge a frozen battery. Allow the battery to warm to 60° F (15.5° C) before placing on charger.

CHARGING A COMPLETELY

DISCHARGED BATTERY

1. Be aware of all the safety precautions you should observe during the charging operation. If you are unfamiliar with the use of a battery charger and hydrometer, have the battery serviced by your dealer.

2. Add distilled water sufficient to cover the plate (fill to the proper level near the end of the charge). If the battery is extremely cold, allow it to warm before adding water because the water level will rise as it warms. Also, an extremely cold battery will not accept a normal charge until it becomes warm.

3. Always unplug or turn the charger off before attaching or removing the clamp connections.

4. Carefully attach the clamps to the battery in proper polarity (usually red to [+] positive and black to [-] negative).

5. While charging, periodically measure the temperature of the electrolyte. If the temperature exceeds 125° F

(51.6° C), or if violent gassing or spewing of electrolyte occurs, the charging rate must be reduced or temporarily halted to prevent battery damage.

JUMP STARTING WITH AUXILIARY

(BOOSTER) BATTERY

Jump starting is not recommended. However, if it must be done, follow these directions. Both booster and discharged batteries should be treated carefully when using jumper cables. Follow the steps below EXACTLY, being careful not to cause sparks. Refer to Figure 42 .

1. Both batteries must be of the same voltage.

2. Position the vehicle with the booster battery adjacent to the vehicle with the discharged battery so that booster cables can be connected easily to the batteries in both vehicles. Make certain vehicles do not touch each other.

3. Wear safety glasses and shield eyes and face from batteries at all times. Be sure vent caps are tight.

Place damp cloth over vent caps on both batteries.

4. Connect positive (+) cable to positive post of discharged battery (wired to starter or solenoid).

5. Connect the other end of same cable to same post marked positive (+) on booster battery.

6. Connect the second cable negative (-) to other post of booster battery.

7. Make final connection on engine block of stalled vehicle away from battery. Do not lean over batteries.

8. Start the engine of the vehicle with the booster battery. Wait a few minutes, then attempt to start the engine of the vehicle with the discharged battery.

9. If the vehicle does not start after cranking for thirty seconds, STOP PROCEDURE. More than thirty seconds seldom starts the engine unless some mechanical adjustment is made.

10. After starting, allow the engine to return to idle speed.

Remove the cable connection at the engine or frame.

Then remove the other end of the same cable from the booster battery.

11. Remove the other cable by disconnecting at the discharged battery first and then disconnect the opposite end from the booster battery.

12. Discard the damp cloths that were placed over the battery vent caps.

WARNING

Any procedure other than the preceding could result in:

(1) personal injury caused by electrolyte squirting out the battery vents,

(2) personal injury or property damage due to battery explosion,

(3) damage to the charging system of the booster vehicle or of the immobilized vehicle.

Do not attempt to jump start a vehicle having a frozen battery because the battery may rupture or explode. If a frozen battery is suspected, examine all fill vents on the battery. If ice can be seen or if the electrolyte fluid cannot be seen, do not attempt to start with jumper cables as long as the battery remains frozen.

WARNING

For your personal safety, use extreme care when jump starting. Never expose battery to open flame or electric spark – battery action generates hydrogen gas which is flammable and explosive.

Do not allow battery acid to contact skin, eyes, fabrics, or painted surfaces. Batteries contain a sulfuric acid solution which can cause serious personal injury or property damage.

When removing or installing battery cables, disconnect the negative cable FIRST and reconnect it LAST. If not done in this order, the positive terminal can be shorted to the frame by a tool.

To avoid engine damage, do not disconnect battery while engine is running. Be sure terminal connections are tight before starting.

Lawn Care

& Mowing Information

GENERAL INFORMATION

Proper mowing is an important part of maintaining your lawn in the best possible condition. A healthy and well maintained lawn is better able to resist drought, weeds, and other stresses. But too much maintenance is as detrimental to your lawn as neglect. Proper care for your lawn involves more than just “cutting the grass.” To have a healthy lawn, you need to know:

✘ Types of Grass, Climate and Conditions

✘ How and When to Water, Fertilize & Aerate

✘ How High to Mow the Grass

✘ When and How Often to Mow

✘ What Mowing Patterns to Use

✘ Proper Mowing Methods

✘ How to Solve Common Mowing Problems

TYPES OF GRASS, CLIMATE AND

CONDITIONS

A variety of grasses are commonly grown in household lawns, but two main groups known as cool-season grasses (varieties of bluegrass, ryegrass, and fescue), and warm-season grasses (typically bermuda, buffalograss, and zoysia varieties) are the most common.

The cool-season grasses are better suited to cooler climates, and do not endure hot and dry weather as well as warm-season grasses, but conversely, the warm-season grasses do not grow as well in cooler climates. Most residential lawns are typically seeded with a mixture of these grasses. (A local nursery or lawn center may help you to identify what kind of grass your lawn contains from a sample.)

Knowing your climate and conditions is also important to proper lawn care. Drier climates or conditions will require additional watering, while wetter climates may require more frequent mowing.

HOW AND WHEN TO WATER,

FERTILIZE & AERATE

Every lawn’s watering needs are unique and are dependent upon the type of grass and soil, the amount of local rainfall, and other conditions. Most lawns are watered

too often, but with too little water. However too much water can allow development of diseases with your lawn.

It is best to water the lawn only when necessary, and then to water it slowly, evenly, and deeply—imitating a slow, soaking rain.

WHEN TO WATER YOUR LAWN

When the lawn begins to wilt, the grass’s color dulls, or footprints stay compressed for more than a few seconds, the lawn is beginning to dry out, and needs additional moisture. The best time to water is early morning to allow the water to soak deeply into the lawn and reduce the amount that evaporates in the hot afternoon sun.

HOW TO WATER YOUR LAWN

The best method of watering a lawn is to imitate a slow, soaking rain, applying about 1 inch of water. A method of verifying the amount that you have watered, is to place several empty tin cans (low shallow cans work best) in various spots around the lawn, and check the depth of water in the can during the watering process.

HOW TO FERTILIZE YOUR LAWN

Fertilizing with a slow-release fertilizer provides missing nutrients which help create slow, even growth. While opinions vary on the need for fertilizing, when and how much to fertilize will be more a factor of the condition of the lawn and soil than any routine. Remember that overfertilizing can cause harm, and that most fertilizing should be applied in the spring so that it will release into the lawn through the summer. For more information, check with a local nursery or lawn care specialist, and read and follow the fertilizer manufacturer’s instructions.

AERATING YOUR LAWN

Consider aerating your lawn in spring. Using an aerator to remove cores of soil from the lawn increases the speed of clipping decomposition and encourages deeper root growth by opening up the soil and permitting greater movement of water, fertilizer and air.

Lawn Care & Mowing Information

HOW HIGH TO

MOW THE GRASS

Often cutting height is a matter of personal preference. Typically, you should mow the grass when it is is between three and five inches high. The proper cutting height range for a specific lawn will depend upon several factors, including the type of grass, the amount of rainfall, the prevailing temperature, and the lawn’s overall condition.

Cut less than

Cutting the grass too short causes weak, thin grass plants, which are easily damaged by dry periods and pests. Cutting too short is often more damaging than allowing the grass to be slightly higher.

Letting grass grow a bit longer—especially when it is hot and dry—reduces heat build-up, preserves needed moisture and protects the grass from heat damage and other problems.

However, allowing grass to grow too high can cause thin turf and additional problems.

Cutting off too much at one time shocks the plant’s growth system and weakens the grass plants. A good rule of thumb is the 1/3 rule: to cut no more than one third of the grass height, and never more than 1 inch at a time.

The amount of grass you are able to cut in one pass is also effected by the type of mowing system you are using (for example, broadcasting with side discharge decks can process a much larger volume of grass than mulching does).

Tall Grass Requires Incremental Cutting

For extremely tall grass, set the cutting height at maximum for the first pass, and then reset it to the desired height and mow a second or third time.

Don’t cover the grass surface with a heavy layer of clippings. Consider using a grass collection system and starting a compost pile.

LC—2


WHEN AND HOW OFTEN TO MOW

The time of day and condition of the grass greatly affect the results you’ll get when mowing. For the best results, follow these guidelines:

● Mow when the grass is between three and five inches high.

● Mow with sharp blades. Short clippings of grass one inch or shorter decompose more quickly than longer blades. Sharp mower blades cut grass cleanly and efficiently, preventing frayed edges which harm the grass.

● Mow at time of day when the grass is cool and dry.

Late afternoon or early evening often provide these ideal mowing conditions.

● Avoid mowing after rain or even heavy dew, and never mulch when the grass is wet (moist grass does not mulch well, and clumps beneath the mower deck).

WHAT MOWING PATTERNS TO USE

Always start mowing on a smooth, level area.

The size and type of area to be mowed will determine the best mowing pattern to use. Obstructions such as trees, fences and buildings, and conditions such as slopes and grades must also be considered.

● Cut long straight strips overlapping slightly.

● Where possible, change patterns occasionally to eliminate matting, graining or a corrugated appearance.

● For a truly professional cut, mow across the lawn in one direction, then recut the lawn by mowing perpendicular to the previous cut.

Where possible, make one or two passes around the outside of the area discharging the grass INTO the lawn to keep the cut grass off fences and walks.

Note: Always operate the engine at full throttle when mowing.

If you hear the engine slowing down, you are mowing too fast—using a slower ground speed will improve the cutting efficiency of the blades and prevents many common cutting problems. Use an appropriate ground speed for the thickness and height of the grass you are cutting (3rd gear or slower for manual gear models). If you hear the engine slowing down you are mowing too fast, use a slower ground speed.

The remainder of the mowing should be done in the opposite direction so that the clippings are dispersed

OUT onto the area of lawn previously cut.

MOWING METHODS

Proper Broadcast Mowing

Broadcasting, or side-discharging, disperses fine clippings evenly over the entire lawn. Many golf courses use this method. Your mower has a deep dish deck to allow freer circulation of clippings so they are broadcast evenly over the lawn.

ENGINE SPEED & GROUND SPEED FOR BROADCASTING

Always operate the engine at full throttle when mowing.

If you hear the engine slowing down, you are mowing too fast—using a slower ground speed will improve the cutting efficiency of the blades and prevents many common cutting problems.

ALWAYS use an appropriate ground speed for the thickness and height of the grass you are cutting (3rd gear or slower for manual gear models). If you hear the engine slowing down you are mowing too fast, use a slower ground speed.

HOW MUCH GRASS TO CUT OFF WHEN BROADCASTING

Mow when the grass is 3-5 inches long. Do not cut the grass shorter than 2 to 2-1/2 inches. Do not cut off more that 1 inch of grass in a single pass.

Proper Mulching

Mulching consists of a mower deck which cuts and recuts clippings into tiny particles and which then blows them down

INTO the lawn. These tiny particles decompose rapidly into byproducts your lawn can use.

Mulching Action

UNDER PROPER CONDI-

TIONS, your mulching mower will virtually eliminate noticeable clippings on the lawn surface.

NOTE: When mulching under heavy cutting conditions, a rumbling sound may be present and is normal.

MULCHING REQUIRES EXCELLENT MOWING

CONDITIONS

HOW MUCH GRASS TO MULCH

The best mulching action typically results from cutting only the top 1/2 inch to 3/4 inch of grass blade. This provides short clippings which decompose properly the cutting height and ground speed until you achieve the best cut. Start with a high cutting height and using progressively lower settings until you find a cutting height that is matched to your mowing conditions and preferences.

(much more quickly than longer clippings). The ideal cutting height will vary with climate, time of year, and quality of your lawn. We recommend that you experiment with both

Mulching mowers cannot function properly if the grass is wet, or if the grass is simply to high to cut. Even more than normal mowing, mulching requires that the grass be dry and the the appropriate amount is cut.

Do not use the mower as a mulching mower during the first two or three mowings in the spring. The long grass blades, quick growth, and often wetter conditions are more suitable for broadcasting (side-discharging) or grass bagging operation.

LEAF SHREDDING (USE WITH OPTIONAL MULCHER KIT)

Simplicity’s patented Shredder Blades virtually eliminate raking leaves. Up to 512 cutting edges pulverize leaves into tiny particles, which quickly and naturally decompose into food for your lawn. The Shredder Blades must be removed when you mulch grass clippings.

ENGINE SPEED & GROUND SPEED FOR BROADCASTING

Use full engine throttle matched with a slow ground speed so that clippings will be finely cut. Ground speed while mulching should be HALF of the speed that would be used when broadcasting (side discharging) under similar conditions. Since mulching requires more horsepower than broadcasting, using a slower ground speed is vitally important for proper mulching operation.

TIPS On Dealing With Clippings

Clippings are beneficial to your lawn. A common misconception about clippings is that they automatically lead to thatch—this is untrue. Short clippings produced by broadcasting and clippings produced by mulching methods actually contribute to a healthy lawn because they:

✘ Reduce the evaporation of water from your lawn.

✘ Provide a cushioning layer to reduce lawn wear.

✘ Moderate soil temperature.

✘ Clippings act as a safe, non-polluting and inexpensive fertilizer that nourishes your lawn. Fresh cut grass blades are 85% water, and are a rich source of nitrogen which is essential to lush growth. And one garbage bag of clippings contains about 1/4 lb.

of usable organic nitrogen.

COMPOSTING

The best way to recycle excess clippings and leave your lawn looking immaculate is to collect them with an efficient collection system and deposit them in a compost pile. A compost pile is a collection of grass, leaves, and other organic wastes which—when properly tended— decompose into an odorless, topsoil material. This material, in turn, acts as an inexpensive fertilizer for your lawn and garden.

How to start a healthy compost pile:

1 Build a bin using bricks, fencing, cement blocks, etc. or purchase a prefabricated bin from a garden store. The bin should also have venting on each side and from the bottom to the top.

2 Fill the bin with alternating layers of yard waste. Follow this recipe:

First layer: 3-4 inches of chopped brush or other coarse material.

Second layer: 6-8 inches of mixed leaves, grass clippings, sawdust, etc. Materials should be "sponge damp."

Third layer: 1 inch of soil to add micro-organisms that help break down organic matter.

Fourth layer: 1-2 inches of manure to provide the nitrogen needed by micro-organisms.

Keep adding layers until the bin is almost full. Top off with a 4-6 inch layer of straw and scoop out a "basin" to catch rain water.

3 Four or five days later the pile will reach temperatures of

140-160 degrees. At this time you'll notice it settling, a good sign your compost is working properly.

4 After 5-6 weeks, fork materials into a new pile, turning the outside of the old heap into the center of the new one. Add water if necessary. The compost should be ready to use within three to four months when dark brown, crumbly, and earthy-smelling.
