Safety Rules & Information
SLOPE OPERATION
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 drive on it.
Do
• See your authorized dealer for recommendations of available weights to improve stability.
• 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. Choose a slow speed so that you will not have to stop or change speed 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.
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 necessar y, 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 catcher on steep slopes.
CHILDREN
Tragic accidents can occur if the operator is not aler t 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 tur n 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.
TRANSPORTING AND STORAGE

Operating the Zero Turn Rider
ZERO TURN DRIVING PRACTICE
The lever controls of the Zero Tur n 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 Tur n r ider.
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.
You must release the parking brake prior to moving the control levers inward.
BASIC DRIVING
Forward T ravel 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 Speed Balancing Adjustment in the Adjustments section near the back of this manual.
Reverse T ravel 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 r ider tur ns shar ply in reverse as well as forward, and backing up straight takes practice.

.
The BEST method of handling the ground speed control levers is in three steps — as shown in Figure 3.
FIRST place your hands onto the levers as shown.
SECOND, to go forward gradually push the levers forward with your palms.
THIRD, to speed up move the levers farther forward. To slow down smoothly, slowly move the levers toward neutral.

ADVANCED DRIVING
Executing an End-Of-Row Zero Turn
Your Zero Tur n 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 star ting 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 RIGHT ground speed control lever forward slightly while moving the LEFT ground speed control lever back to center and then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider LEFT and slightly overlaps the row just cut—eliminating the need to back up and re-cut missed grass.
As you become more familiar and experi­enced with operating the Zero Turn rider, you will learn more maneuvers that will make your mowing time easier and more enjoyable.
Remember,the more you practice, the better your control of the Zero Turn will be!
Operating the Zero Turn Rider
Practice Turning In Place
To tur n 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.
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.

Turning In-Place
11. Drain fuel system completely or add a 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 a 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 STORA GE
Before starting the unit after it has been stored for a long period of time, perform the following steps.

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.
• If temperature is expected to drop below 35 degrees, refer to Long Term Storage, Item 2.
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. Use an Antifreeze tester to check the cooling system’s level of protection.Read the instr uctions on the Antifreeze container for the appropriate ratio of water to Antifreeze for your geographical area.
3. 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.
4. Clean external surfaces and engine.
5. Prepare engine for storage.See engine owner’s manual.
6. Clean any dirt or grass from cylinder head cooling fins, engine housing and air cleaner element.
7. Cover air cleaner and exhaust outlet tightly with plastic or other waterproof material to keep out moisture, dirt and insects.
8. Completely grease and oil unit as outlined in the Regular Maintenance section.
9. Clean up unit and apply paint or rust preventative to any areas where paint is chipped or damaged.
10. 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.

SUSPENSION HEIGHT ADJUSTMENT
If the rider tilts either side-to-side or front-to-rear, this adjustment will level the frame with the ground.
Although this adjustment may not be necessary, it may be required if additional weight (ie. a grass catcher) is added to the frame or a drive tire is replaced.
NOTE: Perform this adjustment on a hard, level surface such as a concrete floor. Making this adjustment will affect the mower cutting height. For fine cutting height adjustment, see Mower Deck Leveling Adjustment.
To level the frame, first measure the frame height:
1. The measurement to the top side of the front frame rails, just behind the springs and shocks should be 20-5/8” (52,4cm) for each side (see arrow in Figure
29).
2. The measurement to the top of the rear frame rails, at the widest point on the frame behind the drive tires should be 21-3/8” (54,3cm) for each side (see arrow in Figure 30).
3. Loosen the jam nuts and adjust the square-head allen screw located above each spring.
4. After adjusting all four (4) springs, recheck the meas­urements and adjust if necessary.

MOWING HEIGHT ADJUSTMENT
See Mower Deck Leveling Adjustment to ensure that the actual cutting height is consistent with the cutting height adjustment pin placement.
The cutting height adjustment pin (A, Figure 31) controls the mower cutting height. The cutting height is adjustable between 1-3/4” (4,4cm) and 5” (12,7cm) in 1/4” (0,64cm) increments.
Depress the deck lift foot pedal (B, Figure 31), placing the majority of the force on the top edge of the pedal until it locks into the “TRANSPORT” position.
Place the cutting height adjustment pin in the desired cutting height. Depress the deck lift foot pedal, placing the majority of the force on the bottom edge of the pedal to release the pedal from the “TRANSPORT”position.
MOWER DECK LEVELING ADJUSTMENT
1. Place the cutting height quick pin in the 4” setting.
2. Measure the front and back edges of the mower deck. It should measure 4-1/2” (11,4cm) from the ground to the front lower edge of the mower deck and 3-5/8” (9,2cm) from the back lower edge to the ground. These measurements should be made par­allel to the frame of the tractor, in-line with the outer blade spindle housings on both sides of the mower deck (see Figure 32)
3. If the measurements taken do not match the dimen­sions specified, adjust the front and rear hanger assemblies.
4. Using a 3/4” wrench and socket, adjust the front and rear hanger assemblies (Figure 33) until the meas­urements are achieved, making sure the deck lift pedal arm is still resting against the quick pin.

PTO CLUTCH ADJUSTMENT
Check the PTO clutch adjustment after the initial 50 hour break-in period and then after every 250 hours of opera­tion. Also perform the following procedure if the clutch is slipping or will not engage, or if a new clutch has been installed.
1. Remove key from ignition switch and disconnect spark plug wires to prevent the possibility of acciden­tal starting while the PTO is being adjusted.
2. See Figure 35. Note the position of the 3 adjustment windows (A) in the side of the brake plate and the nylock adjustment nuts (B).
3. Insert a .016” - .018” (0,40mm - 0,45mm) feeler gauge (C) through each window, positioning the gauge between the rotor face and the armature face as shown in Figure 36.
4. Alternately tighten the adjustment nuts (B, Figure 35) until the rotor face and armature face just contacts the gauge.
5. Check the windows for an equal amount of tension when the gauge is inserted and removed, and make any necessary adjustments by tightening or loosen­ing the adjustment nuts.
NOTE: The actual air gap between the rotor and arma­ture may vary even after performing the adjustment pro­cedure. This is due to dimensional variations on compo­nent parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower blades and mower drive belt should come to a com­plete stop within five (5) seconds after the electric PTO switch is turned off.
Blade Brake Check
Mower blades and mower drive belt should come to a complete stop within five (5) seconds after electric PTO switch is turned off.
1. With parking brake engaged, PTO disengaged and an operator in the seat, start the engine engine.
2. Look down through the gap between the left side of the floor and frame rail and observe the PTO drive belt. Engage the PTO and wait several seconds. Disengage the PTO and check the amount of time it takes for the mower drive belt to stop.
3. If the mower drive belt does not stop within five (5) seconds, perform the PTO Clutch Adjustment. If the belt still does not stop within five (5) seconds, see your dealer.

BATTERY SERVICE
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.
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.
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 batter y 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.
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 44.
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 star ter 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 thir ty sec­onds seldom starts the engine unless some mechan­ical adjustment is made.
10.After star ting, 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
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, buffalo grass, 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.
LC-1
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.
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

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.
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).
NOTE: We cover some specific mowing instructions for mulching and broadcasting later in this Lawn Care section.
Proper Cutting Height
Cut Here On Second Pass
Cut Here On First Pass
Optimal cutting point at less than 1/3 from top of grass blade
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-3
Lawn Care & Mowing Information
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.
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:
l Mow when the grass is between three and five inches
high.
l 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.
l Mow at time of day when the grass is cool and dry.
Late afternoon or early evening often provide these ideal mowing conditions.
l 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.
l Cut long straight strips overlapping slightly.
l Where possible, change patterns occasionally to
eliminate matting, graining or a corrugated appear­ance.
l For a truly professional cut, mow across the lawn in
one direction, then recut the lawn by mowing perpen­dicular to the previous cut.
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.
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.
LC-4
Lawn Care & Mowing Information
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. UNDER PROPER CONDI­TIONS, 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
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.
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.
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 (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 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.

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 pur-
chase 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.
