TOWED EQUIPMENT• Never allow children or others in or on towed equip-

ment.• Tow only with a machine that has a hitch designed

for towing. Do not attach towed equipment except atthe hitch point.

• Follow the manufacturer’s recommendations forweight limit for towed equipment and towing onslopes.

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

• Travel slowly and allow extra distance to stop.• Do not shift to neutral and coast down hill.

Safety Rules and Information

SLOPE OPERATIONSlopes 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 theslope or if you feel uneasy on it, do not operate on it.Control of a ride-on machine sliding on a slope will not beregained by the application of the brake. The main rea-sons for loss of control are: insufficient tire grip on theground, speed too fast, inadequate braking, the type ofmachine is unsuitable for it’s task, lack of awareness of theground 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 orshift while on the slope.

• Use extra care with grass catchers or other attach-ments. 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 travelingdownhill. 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 straightdown 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 embank-ments. The mower could suddenly turn over if awheel is over the edge of a cliff or ditch, or if an edgecaves in.

• Do not mow on wet grass. Reduced traction couldcause sliding.

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

WARNINGNever operate on slopes greater than 17.6 percent(10°) which is a rise of 3-1/2 feet (106 cm) vertically in20 feet (607 cm) horizontally. When operating on slopes use additional wheelweights or counterweights. See your dealer todetermine which weights are available andappropriate for your unit. Select slow ground speed before driving onto slope.In addition to front and rear weights, use extra cautionwhen operating on slopes with rear-mounted grasscatcher.Mow UP and DOWN the slope, never across theface, use caution when changing directions and DONOT START OR STOP ON SLOPE.

ChildrenTragic accidents can occur if the operator is not alert to thepresence of children. Children are often attracted to theunit and the mowing activity. Never assume that childrenwill remain where you last saw them.

• Keep children out of the mowing area and under thewatchful 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 seri-

ously 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 obscurevision.

EMISSIONS• Engine exhaust from this product contains chemicals

known, in certain quantities, to cause cancer, birthdefects, or other reproductive harm.

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

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

• Never make adjustments or repairs with the enginerunning unless specified otherwise in the engine man-ufacturer’s manual.

• Do not remove the fuel filter when the engine is hotas spilled gasoline may ignite. Do not spread fuel lineclamps further than necessary. Ensure clamps griphoses firmly over the filter after installation.

• Do not use gasoline containing METHANOL, gasoholcontaining more than 10% ETHANOL, gasoline addi-tives, or white gas because engine/fuel system dam-age could result.

• If the fuel tank must be drained, it should be drainedoutdoors.

• Replace faulty silencers/mufflers.

• Grass catcher components are subject to wear, dam-age, and deterioration, which could expose movingparts or allow objects to be thrown. Frequently checkcomponents and replace with manufacturer’s recom-mended parts, when necessary.

• Mower blades are sharp and can cut. Wrap theblade(s) or wear gloves, and use extra caution whenservicing them.

• Check brake operation frequently. Adjust and serviceas required.

• Use only factory authorized replacement parts whenmaking repairs.

• Always comply with factory specifications on all set-tings and adjustments.

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

• Never attempt to make major repairs on this unitunless you have been properly trained. Improper ser-vice procedures can result in hazardous operation,equipment damage and voiding of manufacturer’swarranty.

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

• Do not change engine governor settings or over-speed the engine. Operating the engine at excessivespeed can increase the hazard of personal injury.

• Disengage drive attachments, stop the engine,remove the key, and disconnect the spark plugwire(s) before: clearing attachment blockages andchutes, performing service work, striking an object, orif the unit vibrates abnormally.

USING A MULCHING MOWER

Benefits of Proper MulchingMulching consists of a mower deck which cuts andrecuts clippings into tiny particles and then blows themdown into the lawn. These tiny particles decomposerapidly into by-products that your lawn can use. Underproper conditions your mulching mower virtually elimi-nate noticeable clippings on the lawn surface.

Limitations of Mulching DecksMulching mowers cannot function properly if the grass iswet, or if the grass is simply too high. Even more thannormal mowing, mulching requires that the grass be dryand no more than 1/3 of the height is cut.

Do not use the mower as a mulching mower during thefirst two or three cuttings in the spring. The long grassblades, quick growth, and often wetter conditions aremore suitable for broadcasting (side-discharging).

Correct Ground Speed & Engine SpeedUse full engine throttle to maximize mower blade tipspeed matched with a slow ground speed so that clip-pings will be finely cut. Ground speed while mulchingshould be half the speed used when broadcasting (side-discharging) under similar conditions. Since mulchingrequires more horse power that broadcasting, using aslower ground speed is vitally important for propermulching operation.

Correct Cutting HeightCutting off too much at one time shocks the plantsgrowth system and weakens the grass plants. A goodrule of thumb is the 1/3 rule: to cut no more than onethird of the grass height, and never more than 1 inch at atime.

The best mulching action typically results from cuttingonly the top 1/2” to 3/4” of the grass blade. This providesshort clippings which decompose properly (much morequickly than longer clippings). The ideal cutting heightwill vary with climate, time of year, and quality of yourlawn. We recommend that you experiment with both thecutting height and ground speed to achieve the best cut.Start with a high cutting height and use progressivelylower heights until you find a cutting height that ismatched to your mowing conditions and preferences. Forbest results, overlapping is recommended.

Using the Side Discharge DeflectorWhen to use the side discharge deflector: If you’vebeen on vacation or missed a mowing and the grass hasgotten very long, do not try to mulch at your normal cut-ting height. To handle these situations your mulchingmower is equipped with a side discharge deflector.Installing the side discharge deflector allows you tobroadcast clippings. Broadcasting, or side-discharging,disperses fine clippings evenly over the entire lawn.Many golf courses use this method. Your mower has adeep dish deck to allow freer circulation of clippings sothey are broadcast evenly over the lawn.

Always operate the engine at full throttle. Use an appro-priate ground speed for the thickness and height of grassyou are cutting. If you hear the engine slowing down,you are mowing too fast, use a slower ground speed.Mow when the grass is 3”-5”long. Do not cut off morethan 1” in a single pass.

To install the side discharge chute:

1. Lift up the mulching cover (B, Figure 3).

2. Install the side discharge deflector (A) under themulching cover. The side discharge deflector hooksonto the mulching cover hinge rod, and is held inplace by the mulching cover.

3. Release the mulching cover.

BATTERY CHARGING

A dead battery or one too weak to start the engine maybe the result of a defect in the charging system or otherelectrical component. If there is any doubt about thecause of the problem, see your dealer. If you need toreplace the battery, follow the steps under Cleaning theBattery & Cables in the Regular Maintenance Section.

To charge the battery, follow the instructions provided bythe battery charger manufacturer as well as all warningsincluded in the safety rules sections of this book. Chargethe battery until fully charged (until the specific gravity ofthe electrolyte is 1.250 or higher and the electrolyte tem-perature is at least 60° F). Do not charge at a rate high-er than 10 amps.

WARNINGKeep open flames and sparks away from thebattery; the gasses coming from it are highlyexplosive. Ventilate the battery well duringcharging.

SEAT ADJUSTMENTThe seat can be moved forward and back by moving thelever (A, Figure 23) underneath the front of the seat, thenpositioning the seat as desired.

Figure 23. Seat Adjustment A. Seat Adjustment Lever

STEERING GEAR ADJUSTMENTIf there is excessive slack in the steering system, thesteering gear backlash can be removed.

1. See Figure 24. Locate the steering gear assembly onthe underside of the tractor. Loosen the two nuts andadjust the bracket so the gear teeth are closelymeshed.

2. Tighten nuts (A, Figure 24) to 36-44 ft. lbs. (49-59Nm) after adjustment.

PTO CLUTCH ADJUSTMENTCheck the PTO clutch adjustment after the initial 25 hourbreak-in period and then after every 250 hours of opera-tion. Also perform the following procedure if the clutch isslipping or will not engage, or if a new clutch has beeninstalled.

1. Remove key from ignition switch and disconnectspark plug wires to prevent the possibility of acciden-tal starting while the PTO is being adjusted.

2. See Figure 26. Note the position of the 3 adjustmentwindows (A) in the side of the brake plate and thenylock adjustment nuts (B).

3. Insert a .012”-.015” (2,5-4mm) feeler gauge (C)through each window, positioning the gauge betweenthe rotor face and the armature face as shown inFigure 27.

4. Alternately tighten the adjustment nuts (B, Figure 26)until the rotor face and armature face just contacts thegauge.

5. Check the windows for an equal amount of tensionwhen the gauge is inserted and removed, and makeany necessary adjustments by tightening or looseningthe adjustment nuts.

NOTE: The actual air gap between the rotor and arma-ture may vary even after performing the adjustment pro-cedure. This is due to dimensional variations on compo-nent parts, and is an acceptable condition.

6. Check the mower blade stopping time. The mowerblades and mower drive belt should come to a com-plete stop within five seconds after the electric PTOswitch is turned off.

MOWER ADJUSTMENTS

Leveling The MowerIf the cut is uneven, the mower may need leveling.Unequal or improper tire pressure may also cause anuneven cut. Make sure tire pressure is correct as speci-fied in Checking Tire Pressure.

ALL MODELS

1. With the mower installed, place the tractor on asmooth, level surface such as a concrete floor. Turnthe front wheels straight forward.

2. Check for bent blades and replace if necessary.

3. Disengage the PTO. Place the mower in mid-cutposition. Arrange one of the mower blades so that itis pointing from side-to-side.

4. Measure the distance between the outside tips ofeach blade and the ground. If there is more than 1/8”(3mm) difference between the measurements oneach side, proceed to step 5. If the difference is 1/8”(3mm) or less, proceed to step 6.

5. See Figure 28. Loosen the outside nut (A). Turn theeccentric nut (B) to raise or lower left-hand side ofmower. When mower is level, hold the eccentric nutwhile tightening the outside nut.

NOTE: When using a turbo collection system, raise thedischarge side of the mower approximately 1/4” to com-pensate for turbo assembly weight. Check level of cutgrass and adjust the 1/4” measurement if necessary fora smooth even cut.

HOW AND WHEN TOWATER, FERTILIZE &AERATEMost lawns are watered too often,but with too little water. Howevertoo much water can allow develop-ment of diseases with your lawn. It isbest to water the lawn only whennecessary, and then to water itslowly, evenly, and deeply—imitat-ing a slow, soaking rain.WHEN TO WATER YOUR LAWN

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

HOW TO WATER YOUR LAWN

The best method of watering a lawnis to imitate a slow, soaking rain,applying about 1 inch of water. HOW TO FERTILIZE YOUR LAWN

Fertilizing with a slow-release fertiliz-er provides missing nutrients whichhelp create slow, even growth.Remember that over-fertilizing cancause harm, and that most fertilizingshould be applied in the spring sothat it will release into the lawnthrough the summer.

AERATING YOUR LAWN

Consider aerating your lawn in spring. Using an aeratorto remove cores of soil from the lawn increases thespeed of clipping decomposition and encourages deeperroot growth by opening up the soil and permitting greatermovement of water, fertilizer and air.

HOW HIGH TO MOW THE GRASSCutting the grass too short causes weak, thingrass plants, which are easily damaged by dryperiods and pests.

Letting grass grow a bit longer—especially when itis hot and dry—reduces heat build-up, preservesneeded moisture and protects the grass from heatdamage and other problems.

Cutting off too much at one time shocks the plant’sgrowth system and weakens the grass plants. Agood rule of thumb is the 1/3 rule: to cut nomore than one third of the grass height, andnever more than 1 inch at a time.

CutHere OnSecondPass

Cut Here OnFirst Pass

Optimal cutting pointat less than 1/3 from topof grass blade

Tall Grass Requires Incremental CuttingFor extremely tall grass, set the cutting height at maxi-mum for the first pass, and then reset it to the desiredheight and mow a second or third time.

Don’t cover the grass surface with a heavy layer ofclippings.

Lawn Care & Mowing Information

WHEN AND HOW OFTEN TO MOWThe time of day and condition of the grass greatly affect the results you’llget 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 shorterdecompose more quickly than longer blades. Sharp mower blades cutgrass cleanly and efficiently, preventing frayed edges which harm thegrass.

� Mow at time of day when the grass is cool and dry. Late afternoon orearly evening often provide these ideal mowing conditions.

� Avoid mowing after rain or even heavy dew, and never mulch when thegrass is wet (moist grass does not mulch well, and clumps beneath themower 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 toofast—maintaining a slower ground speed will improve thecutting efficiency of the blades and prevents many com-mon cutting problems.

Select an appropriate ground speed for the thicknessand height of the grass you are cutting (3rd gear or slow-er for manual gear models, or mid-range or slower forhydro models). If you hear the engine slowing down youare 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. Donot cut off more that 1” (2.5cm) of grass in a single pass.
