SAFETY RULES
GENERAL OPERATION
1. Read, understand, and follow all instructions in the manual and on the unit before starting.
2. Do not put hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.
3. Only allow responsible adults, who are familiar with the instructions, to operate the unit (local regulations can restrict operator age).
4. Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade(s).
5. Be sure the area is clear of other people before mowing. Stop the unit if anyone enters the area.
6. Never carry passengers.
7. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while travelling in reverse.
8. Never direct discharge material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blade(s) when crossing gravel surfaces.
9. Do not operate the machine without the entire grass catcher, discharge guard (deflector), or other safety devices in place and operational.
10. Slow down before turning.
11. Never leave a running unit unattended. Always disengage the blades (PTO), set parking brake, stop engine, and remove keys before dismounting.
12. Disengage blades (PTO) when not mowing. Shut off engine and wait for all parts to come to a complete stop before cleaning the machine, removing the grass catcher, or unclogging the discharge guard.
13. Operate the machine only in daylight or good artificial light.
14. Do not operate the unit while under the influence of alcohol or drugs.
15 Watch for traffic when operating near or crossing
roadways.
16. Use extra care when loading or unloading the unit into a trailer or truck.
17. Always wear eye protection when operating this unit.
18. Data indicates that operators, age 60 years and above, are involved in a large percentage of power equipment-related injuries. These operators should evaluate their ability to operate the equipment safely enough to protect themselves and others from injury.
19. Follow the manufacturer’s recommendations for wheel weights or counterweights.
20. Keep in mind the operator is responsible for accidents occurring to other people or property.
21. All drivers should seek and obtain professional and practical instruction.
22. Always wear substantial footwear and trousers. Never operate when barefoot or wearing sandals.
23. Before using, always visually check that the blades and blade hardware are present, intact, and secure. Replace worn or damaged parts.
24. Disengage attachments before: refueling, removing an attachment, making adjustments (unless the adjustment can be made from the operator’s position).
25. When the machine is parked, stored, or left unattended, lower the cutting means unless a positive mechanical lock is used.
26. Before leaving the operator’s position for any reason, engage the parking brake, disengage the blades (PTO), stop the engine, and remove the key.
27. To reduce fire hazard, keep the unit free of grass, leaves, & excess oil. Do not stop or park over dry leaves, grass, or combustible materials.
28. It is a violation of California Public Resource Code Section 4442 to use or operate the engine on or near any forest-covered, brush-covered, or grass-covered land unless the exhaust system is equipped with a spark arrester meeting any applicable local or state laws. Other states or federal areas may have similar laws.
29. OSHA regulations may require the use of hearing protection when exposed to sound levels greater than 85 dBA for an 8 hour time period.
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.

le of amputating hands and f
eet and throwing objects.
The triangle in text signifies important cautions or warnings which must be followed.
TRANSPORTING AND STORAGE
1. When transporting the unit on an open trailer, make sure it is facing forward, in the direction of travel. If the unit is facing backwards, wind lift could damage the unit.
2. Always observe safe refueling and fuel handling practices when refueling the unit after transportation or storage.
3. Never store the unit (with fuel) in an enclosed poorly ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion. Fuel vapor is also toxic to humans and animals.
4. Never store the unit or fuel container inside where there is an open flame or pilot light, such as near a water heater. Allow unit to cool before storing.
CAUTION
This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss though extended periods of exposure.
Wear hearing protection when operating this machine.
3
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.
1. Keep children out of the mowing area and under the watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and down for small children.
4. Never carry children, even with the blade(s) off. They may fall off and be seriously injured or interfere with safe unit operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
EMISSIONS
1. Engine exhaust from this product contains chemicals known, in certain quantities, to cause cancer, birth defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and Air Index information on the engine emissions label.
IGNITION SYSTEM
1. This spark ignition system complies with Canadian ICES-002.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip­over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not operate on it.
Control of a walk-behind or 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 its task, lack of awareness of the ground conditions, incorrect hitching and load distribution.
1. Mow up and down the face of slopes, not across.
2. Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop or change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Avoid starting, stopping, or turning on a slope. If tires lose traction (i.e. machine stops forward motion on a slope), disengage the blade(s) (PTO) and drive slowly off the slope.
6. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the machine to rollover.
7. Use extra care while operating machines with grass catchers or other attachments; they can affect the stability of the unit. Do not use on steeps slopes.
8. Do not try to stabilize the machine by putting your foot on the ground (ride-on units).
9. 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.
10. Do not use grass catchers on steep slopes.
11. Do not mow slopes if you cannot back up them.
12. See your authorized dealer/retailer for recommendations of wheel weights or counterweights to improve stability.
13. Remove obstacles such as rocks, tree limbs, etc.
14. Use slow speed.Tires may lose traction on slopes even through the brakes are functioning properly.
15. Do not turn on slopes unless necessary, and then, turn slowly and gradually uphill, if possible. Never mow down slopes.
TOWED EQUIPMENT (RIDE-ON UNITS)
1. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.
2. Follow the manufacturer’s recommendations for weight limit for towed equipment and towing on slopes. See attaching a trailer under OPERATION.
3. Never allow children or others in or on towed equipment.
4. On slopes, the weight of the towed equipment may cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.
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.
Select slow ground speed before driving onto slope. Use extra caution when operating on slopes with rear­mounted grass catchers.
Mow up and down the face of slopes, not across. Use caution when changing directions and DO NOT START OR STOP ON SLOPE.
4
WARNING: To avoid serious injury, operate your unit up and
down the face of slopes, never across the face. Do not operate
on slopes greater than 10 degrees. Make turns gradually to
prevent tipping or loss of control. Exercise extreme caution
when changing direction on slopes. Braking may be affected by
attachments. Reduce speed on slopes.
1. Fold this page along dotted line indicated above.

SERVICE AND MAINTENANCE
Safe Handling of Gasoline
1. Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
2. Use only approved gasoline containers.
3. Never remove the gas cap or add fuel with the engine running. Allow the engine to cool before refueling.
4. Never fuel the machine indoors.
5. Never store the machine or fuel container where there is an open flame, spark, or pilot light such as near a water heater or other appliance.
6. Never fill containers inside a vehicle or on a truck bed with a plastic bed liner. Always place containers on the ground away from your vehicle before filling.
7. Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
8. Keep nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
9. If fuel is spilled on clothing, change clothing immediately.
10. Never over-fill the fuel tank. Replace gas cap and tighten securely.
11. Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.
12. If fuel is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.
13. Replace all fuel tank caps and fuel container caps securely.
Service & Maintenance
1. Never run the unit in an enclosed area where carbon monoxide fumes may collect.
2. Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.
3. Never tamper with safety devices. Check their proper operation regularly and make necessary repairs if they are not functioning properly.
4. Keep unit free of grass, leaves, or other debris build­up. Clean up oil or fuel spillage. and remove any fuel­soaked debris. Allow machine to cool before storage.
5. If you strike an object, stop and inspect the machine. Repair, if necessary, before restarting.
6. Never make adjustments or repairs with the engine running.

19. 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.
20. On multiple blade mowers, take care as rotating one blade can cause other blades to rotate.
21. Do not change engine governor settings or over­speed the engine. Operating the engine at excessive speed can increase the hazard of personal injury.
22. 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.
23. Never place hands near the moving parts, such as a hydro pump cooling fan, when the tractor is running. (Hydro pump cooling fans are typically located on top of the transaxle).
24. Units with hydraulic pumps, hoses, or motors: WARNING: Hydraulic fluid escaping under pressure may have sufficient force to penetrate skin and cause serious injury. If foreign fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. Keep body and hands away from pin holes or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, and not hands, to search for leaks. Make sure all hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. If leaks occur, have the unit serviced immediately by your authorized service center.
25. WARNING: Stored energy device. Improper release of springs can result in serious personal injury. Springs should be removed by an authorized technician.

Ground Speed Levers /
Parking Brake
These levers control the ground speed and parking brake of the rider. The left lever controls the left rear drive wheel and the right lever controls the right rear drive wheel and parking brake.
Pushing the levers out to the side, away from the operator’s lap, locks the parking brake in PARK position (inset, Figure 1). This is the proper position for starting the rider. Pulling the levers in across the operator’s lap puts the levers in DRIVE positions.
From DRIVE position, moving a lever forward increases the FORWARD speed of the associated wheel. Pulling back on a lever increases the REVERSE speed. The further a lever is pushed, the faster the drive wheel will turn.
See DRIVING PRACTICE for steering instructions.
Engine Speed Control
The engine speed control adjusts engine speed. Always set the engine speed to FAST for driving and mowing. Move the engine speed control back to SLOW to decrease engine speed. NEVER turn on the mower blades with the engine speed set to SLOW. Only turn on the mower blades with the engine speed set to FAST.
Choke
CLOSE the choke for cold starting (pull knob up). OPEN the choke once the engine starts (push knob down). If the engine is warm, it may not require choking. If this is the case, set the choke to OPEN (push the knob down) while cranking the engine. In most cases, you will need to close the choke in order to start the engine.

Mower Cutting Height Switch
To increase the mower cutting height (raise the mower deck), press the top of the yellow cutting height switch. To decrease mower cutting height (lower the mower deck), press the bottom of the switch. Mower cutting height range is approximately 3-3/4” to 1-1/2”. The cutting height gauge indicates the position of the mower deck. The cutting height gauge is located on the front of the rider, just behind the driver’s left leg.
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.
Hour Meter
The hour meter measures the number of hours the key has been in the RUN position.
NOTE: The hour meter will register the passage of time when the key is in the RUN position, even if the engine is not running.
Mower Blade Switch
The yellow mower blade switch turns the mower blades on and off. To turn the mower blades ON, pull the switch up. To turn the mower blades OFF, push the switch down. Always set the engine speed control to FAST before turning the mower blades ON, and while mowing.
Transmission Release Levers
The transmission release levers deactivate the transmissions so that the unit can be pushed by hand. See PUSHING THE UNIT BY HAND for operational information.
Fuel Tank
To remove the fuel tank cap, turn it counterclockwise.
GENERAL OPERATING SAFETY
Before first time operation:
• Be sure to read all information in the Safety and Operation sections before attempting to operate this rider and mower.
• Become familiar with all of the controls and how to stop the unit.
• Drive in an open area without mowing to become
accustomed to driving the unit.
WARNING
If you do not understand how a specific control functions, or have not yet thoroughly read the CONTROL FUNCTIONS section, do so now. Do NOT attempt to operate the rider without first becoming familiar with the location and function of ALL controls.
10
WARNING
Never allow passengers to ride on the unit.
Before leaving the operator’s position for any reason, engage the parking brake and disengage the PTO. Never leave the unit unattended (i.e. out of sight) with the engine running.
To reduce fire hazard, keep the engine, rider and mower free of grass, leaves and excess grease. Do not stop or park rider over dry leaves, grass or combustible materials.
Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is still hot from recent operation. Do not allow open flame, smoking or matches in the area. Avoid over-filling and wipe up any spills.
Figure 2. Pre-Start Checks A. Fuel Tank Cap

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.
Select slow ground speed before driving onto a slope. Use extra caution when operating on slopes with a rear-mounted grass catcher.
Mow up and down the face of slopes, not across. Use caution when changing directions and DO NOT START OR STOP ON A SLOPE.
Do not load this zero-turn rider on a trailer or truck using two separate ramps. Only use a single ramp that is at least one foot wider than the width of the rear wheels of this rider. This rider has a zero turning radius and the wheels could fall off the ramps, or the rider could tip over injuring the operator or bystanders.
WARNING - TRAILERS
CHECKS BEFORE STARTING
• Check that the crankcase oil is filled to full mark on dipstick (see CHECK ENGINE OIL in the Maintenance section).
• Fill the fuel tank with fresh fuel.
FUEL RECOMMENDATIONS
For daily operation: Use only unleaded gasoline with a
pump sticker octane rating of 87 or higher. Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is approved as a fuel. Methyl Teriary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE by volume) are approved as a fuel. Do not use unapproved gasolines, such as E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. This will damage the engine components and void the engine warranty. Do not use fuel additives other than fuel stabilizer.
For storage: CAUTION: Alcohol blended fuels (called gasohol or using 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 always use fuel stabilizer, especially before storage of 30 days or longer. Use fresh fuel next season. See STORAGE instructions for additional information.
Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. To add fuel:
1. Remove the fuel cap (B, Figure 2).
2. Fill the tank. Do not overfill. Leave 2 inches (5 cm) of space in the tank for fuel expansion.
3. Install and hand tighten the fuel cap.
11
PUSHING THE RIDER BY HAND
NOTE: Do not disengage the transmissions if parked on a slope.
1. Turn the mower blades OFF, push the ground speed control levers out to their START/PARK positions, turn the ignition switch OFF, remove the key, and wait for all moving parts to stop.
2. Locate the transmission release levers (C, Figure 3) at the rear of the unit.
3. Pull both levers back and down to release the transmissions (position B, Figure 3).
4. Pull the ground speed control levers in to their DRIVE positions.
The rider can now be pushed by hand.
5. After moving the rider, set the ground speed control levers to START/PARK and push both transmission release levers forward to re-engage the transmissions (position A, Figure 3).

DRIVING PRACTICE -
BASIC DRIVING
WARNING: Never operate on slopes greater than 17.6%
(10°). See SLOPE OPERATION in the safety section. Zero turn riders operate differently from other four­wheeled vehicles. The drive wheels are also your steering wheels. If you cannot drive the unit on a hill, you will not be able to steer the unit on it. Operating zero turn units on slopes requires extra caution.
The lever controls of the zero turn rider are very responsive, and learning to gain a smooth and efficient control of the rider’s forward, reverse, and turning movements will take some practice.
Spend some time going through the following maneuvers 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.
Avoid turf damage! To avoid turf damage, keep both drive wheels moving while executing turns. Pivoting on one wheel, or dragging a wheel through a turn will damage your lawn.
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.
Forward Travel Practice
Gradually move both ground speed control levers evenly FORWARD from neutral. Slow down and repeat.
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 as sharply in reverse as when going forward, and backing up straight takes practice.
Figure 5. Forward Travel
Forward Travel
Figure 6. Reverse Travel
Reverse Travel
Smooth Travel
The lever controls of the zero turn rider are highly responsive.
The BEST method of handling the ground speed control levers is in three steps — as shown in Figure 4.
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 back toward neutral.
Figure 4. Move Control Levers Gradually
WARNING
Do not mow in reverse unless absolutely necessary. Always look down and behind before and while traveling in reverse.
13
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 make a 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. Be sure to keep both wheels moving to avoid turf damage.
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.
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 rider will be!
Practice Turning Around a Corner
While traveling forward allow one handle to gradually return back toward neutral. Practice several times before mowing.
NOTE: To prevent damaging your lawn by pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward.

STORAGE
WARNING
Never store the unit (with fuel) in an enclosed, poorly ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion.
Fuel vapor is also toxic to humans and animals.
STORAGE
Before Storage
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:
• Turn the mower blades OFF, set the ground speed control levers to START / PARK, & remove the key from the ignition switch.
• Check all fluid levels. Check all maintenance items.
• Battery life will be increased if it is removed, put in a cool, dry place and fully charged about once a month. If the battery is left in the unit, disconnect the negative cable.
It is important to prevent gum deposits from forming in the essential fuel system parts such as the carburetor, fuel filter, fuel line, and fuel tank during storage. Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to the separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.
To avoid engine problems use fuel stabilizer, especially before storage of 30 days or longer.
After Storage
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Fill with FRESH fuel.
• After starting, allow the engine to warm before operating.

The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to­engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.

HOW AND WHEN TO WATER, FERTILIZE & AERATE
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.
HOW TO FERTILIZE YOUR LAWN
Fertilizing with a slow-release fertiliz­er provides missing nutrients which help create slow, even growth. Remember that over-fertilizing can cause harm, and that most fertilizing should be applied in the spring so that it will release into the lawn through the summer.
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.

HOW HIGH TO MOW THE GRASS
Cutting the grass too short causes weak, thin grass plants, which are easily damaged by dry periods and pests.
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.
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.
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.
Cutting down to this area contributes to thatch problems
Cut less than
1/3

Lawn Care & Mowing Information
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 3”-4” (7,5-10 cm) 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).
Note: Always operate the engine at full throttle when mowing.
PROPER MOWING SPEED
ENGINE SPEED & GROUND SPEED
Always operate the engine at full throttle when mowing. If you hear the engine slowing down, you are mowing too fast—maintaining a slower ground speed will improve the cutting efficiency of the blades and prevents many com­mon cutting problems.
Select an appropriate ground speed for the thickness and height of the grass you are cutting (3rd gear or slow­er for manual gear models, or mid-range or slower for hydro models). If you hear the engine slowing down you are mowing too fast, use a slower ground speed.
HOW MUCH GRASS TO CUT OFF
Mow when the grass is 3”-4” inches (7,5-10cm) long. Do not cut off more that 1” (2.5cm) of grass in a single pass.
