Slope Operation

Slopes are a major factor related to loss-of-control and tip-over 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.

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 rear-mounted 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.

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.

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.

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 four-wheeled 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.

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

Forward Travel Practice

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

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

WARNING

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

Forward Travel

Figure 5. 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 as sharply in reverse as when going forward, and backing up straight takes practice.

Reverse Travel

Figure 6. Reverse Travel

Operation

Not for

Reproduction

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.

Executing Turns

Figure 7. Right Turn

Practice Turning In Place

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

Turning In Place

Figure 8. Turning in Place

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!

Check / Adjust PTO clutch

WARNING

To avoid serious injury, perform adjustments only with engine stopped, key removed and tractor on level ground.

The Power Take Off (PTO) clutch drives the mower blades. The PTO clutch is engaged and disengaged by the mower blade switch. Check the PTO clutch adjustment every 200 hours of operation. Also perform the following procedure if the clutch is slipping, 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 Figures 24 & 25. 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 .012”-.015” (2,5-4mm) feeler gauge (C, Figure 25) through each window, positioning the gauge between the rotor face and the armature face as shown in Figure 25.

4. Alternately tighten the adjustment nuts (B, Figure 24) 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.

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.

Fuel System

Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs & Stratton® Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs & Stratton genuine service parts are sold.

For engines equipped with a FRESH START® fuel cap, use Briggs & Stratton FRESH START® available in a drip concentrate cartridge.

There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel system before storage.

If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.

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.

Replacement Parts

Replacement parts are available from your authorized dealer. Use only factory authorized parts or like parts when making repairs.

Maintenance Items

Many convenient and helpful service and maintenance items are available from you authorized dealer. Some of these items include:

Look For Relevant Emissions Durability Period and Air Index Information

On Your Small Off-Road Engine Emissions Label

Engines that are certified to meet the California Air Resources Board (CARB) small off-road Emissions Standard must display information regarding the Emissions Durability Period and the Air Index. Briggs & Stratton makes this information available to the consumer on our emissions labels. The engine emissions label will indicate certification information.

The Emissions Durability Period describes the number of hours of actual running time for which the engine is certified to be emissions compliant, ass u m i n g proper maintenance in accordance with the Operating & Maintenance Instructions. The following categories are used:

Moderate:

Engine is certified to be emissions compliant for 125 hours of actual engine running time.

Intermediate:

Engine is certified to be emissions compliant for 250 hours of actual engine running time.

Extended:

Engine is certified to be emissions compliant for 500 hours of actual engine running time. For example, a typical walk-behind lawn mower is used 20 to 25 hours per year. Therefore, the Emissions Durability Period of an engine with an intermediate rating would equate to 10 to 12 years.

Briggs & Stratton engines are certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emissions requirements.

For engines less than 225 cc displacement. Category C = 125 hours, Category B = 250 hours, Category A = 500 hours

For engines of 225 cc or more displacement. Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours

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. The gross power curves can be viewed at www.BRIGGSandSTRATTON. COM. Net power values are taken with exhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine power will be higher than net engine power and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given the wide array of products on which engines are placed, the gas engine may not develop the rated gross power when used in a given piece of power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine components (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.
