GENERAL OPERATION   Read, understand, and follow all instructions in this manual   and on the mower before starting.   In this operator’s manual, left and right, backward and   forward are used in relation to the machine’s normal driving   direction.   Only allow responsible adults, who are familiar with the   instructions, to operate the mower.   Clear the area of objects such as rocks, toys, wire, etc.,   which could be picked up and thrown by the blade.   Be sure the area is clear of bystanders before mowing. Stop   mower if anyone enters the area.   Never direct discharged material toward anyone. Avoid   discharging against a wall or obstruction. Material may   ricochet back toward the operator. Stop the blade(s) when   crossing gravel surfaces.   Do not operate the mower without either the entire grass   catcher or the deflector in place. This will decrease the   possibility of injury from objects being thrown by the mower   blades.   Never carry passengers.   Do not mow in reverse unless absolutely necessary. Always   look down and behind before and while backing.   Never leave a running mower unattended. Always turn off   blades, set Park Brake, stop engine and remove key before   dismounting.   6 Download from Www.Somanuals.com. All Manuals Search And Download.   WARNINGS   Failure to observe the following instructions   could result in serious injury or death.   WARNING   ! GENERAL OPERATION (continued)   Do not put hands or feet near rotating parts or under the   machine. Keep clear of the discharge opening at all times.   Disengage blade(s) 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.   Mow only in daylight or good artificial light.   Do not operate the mower while under the influence of   alcohol or drugs.   Slow down before turning to reduce the risk of tip-over.   Watch for traffic when operating near or crossing roadways.   Use extra care when loading or unloading the mower into a   trailer or truck.   Always wear eye protection when operating machine.   Data indicates that operators, age 60 years and above, are   involved in a large percentage of riding mower-related   injuries. These operators should evaluate their ability to   operate the riding mower safely enough to protect   themselves and others from serious injury.   Follow the manufacturer’s recommendation for wheel weights   and counterweights.   7 Download from Www.Somanuals.com.

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 feel unsure   on any slope, do not mow it!   DO   Mow across the slope with your Dixon ZTR -- never up or   down. This will decrease the risk of tip-over.   Remove obstacles such as rocks, tree limbs, wires and other   foreign objects that can be thrown by mower blades.   Watch for holes, ruts, roots and bumps and uneven terrain   that could overturn the mower. Tall grass can hide such   obstacles.   Use slow speed. Tires may lose traction on slopes even   though the brakes are functioning properly.   Avoid starting or stopping on a slope. If tires lose traction,   disengage the blades and proceed slowly down the slope.   Keep all movement on the slopes slow and gradual. Do not   make sudden changes in speed or direction.   Use extreme caution when operating the mower with   attachments to prevent tip-over or roll-over.   If front wheels lift off the ground, pull levers back to stabilize   the mower. Discontinue mowing the slope!   8 Download from Www.Somanuals.com. All Manuals Search And Download.   WARNINGS   Failure to observe the following instructions   could result in serious injury or death.   WARNING   ! SLOPE OPERATION (continued)   DO NOT   Do not turn on slopes unless necessary, and then, turn   slowly and gradually downhill, if possible. Rapid uphill turns   may cause tip-over.   Do not mow near drop-offs, ditches, or embankments.   Unstable ground may cause loss of control.   Do not mow on wet grass. Reduced traction could cause   sliding.   Do not try to stabilize the mower by putting your foot on the   ground.   Do not use grass catcher or other attachments on steep   slopes. The added weight may change the stability of the   mower thus creating the potential for tip-over.   9 Download from Www.Somanuals.com.

FIRE HAZARDS   Use extra care when handling gasoline and other fuels. They   are flammable and vapors are explosive.   Store all fuel in approved containers specifically designed for   that purpose.   Allow engine to cool before refueling. Never remove fuel cap   or add fuel with engine running.   Do not smoke while refueling or operating the mower.   To reduce fire hazard, keep mower free of grass, leaves and   other debris buildup.   If gasoline is spilled, do not attempt to start the   engine. Move mower away from the area of the spill. Do not   create any source of ignition until gas vapors have   dissipated. Wipe up spilled fuel and dispose of waste   properly.   If fuel is spilled on clothing, change clothing immediately.   Before storing, allow mower to cool. Clean fuel and oil   spillage.   Never store the mower or fuel container inside a building   where there is an open flame.   10   Download from Www.Somanuals.com. All Manuals Search And Download.   WARNINGS   Failure to observe the following instructions   could result in serious injury or death.   WARNING   ! FIRE HAZARDS (continued)   To prevent fire or explosion, keep sparks and open flames   away from battery.   Keep electrical connections clean and tight. Inspect them   often. Loose connections and corrosion increase fire risk.   Before disconnecting the negative ground cable, make sure   all switches are off. This decreases the chance of sparking   and fire.   Use care when backing to avoid pushing the grass bags into   the frame or “hot” exhaust muffler of the engine. Fire could   result.   To prevent fire and explosion caused by static electricity:   Never fill containers inside a vehicle or on a truck or   trailer bed with a plastic liner. Always place containers   on the ground away from your vehicle before filling.   When practical, remove fuel powered equipment from   the truck or trailer and refuel it on the ground. If this is   not possible, refuel such equipment on a trailer with a   portable container, rather than from a fuel dispenser   nozzle.   If a fuel dispenser nozzle must be used, keep the   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.   11   Download from Www.Somanuals.com.

CHILDREN, BYSTANDERS AND PETS   Tragic accidents can occur if the operator is not alert   to the presence of children, bystanders and pets.   Children are attracted to lawn mowers   and the mowing activity.   NEVER assume children, bystanders and pets   will stay where they were last seen.   Be alert to avoid accidents.   Keep bystanders and pets out of the mowing area and keep   children under the watchful care of another responsible adult.   Be alert and turn mower off if bystanders, children or pets   enter the area.   Before and during backing look BEHIND and DOWN for   small children.   Never carry children as passengers. They may fall off and be   seriously injured or interfere with safe mower operation.   Never allow children to operate the mower.   Use extra care when approaching blind corners, shrubs,   trees, or other objects that may obscure vision.   12   Download from Www.Somanuals.com. All Manuals Search And Download.   WARNINGS   Failure to observe the following instructions   could result in serious injury or death.   WARNING   ! SERVICE   Never run a mower inside a closed area or without proper   ventilation.   Keep nuts and bolts tight, especially blade attachment bolts,   and keep equipment in good condition.   Never tamper with safety devices. Check their proper   operation regularly.   Stop and inspect the equipment if you strike an object.   Repair, if necessary, before restarting.   Never make adjustments or repairs with the engine running   unless otherwise specified.   Grass catcher components are subject to wear, damage and   deterioration that could expose moving parts or allow objects   to be thrown. Frequently check components. Replace with   original equipment parts when necessary.   When servicing blades, wrap blades or wear gloves, and use   extra caution.   Batteries contain sulfuric acid. To prevent burns, avoid   contact with skin, eyes and clothing.   13   Download from Www.Somanuals.com.

There may be instances or   conditions where it is not possible to hide all the recycled or   mulched clippings.   In order to achieve the best results, please read and follow   the mulching tips listed below:   1. Read and follow the installation instructions that are   included with your mulcher.   2. Set the engine speed control to the wide open or full   setting.   3. Place the mower deck cut height selector in either the top   or second notch. Never cut more than   ¾" (19 mm) to 1" (25mm) off the grass at any one time.   Attempting to cut more grass will result in the deck   plugging and cause the engine to stall.   4. It may be necessary to cut the lawn twice to achieve   acceptable mulching performance especially on first   cuttings or if the lawn is heavily fertilized.   5. Do not attempt to cut grass when it is wet. Mulching   performance will be very poor in wet grass conditions.   6. Maintain sharp blades throughout the cutting season. This   is very important. Optimal mulching performance cannot   be obtained with a dull or nicked blade.   28   Download from Www.Somanuals.com. All Manuals Search And Download.   OPERATION INSTRUCTIONS   MOWING WITH A MULCHING ATTACHMENT   (continued)   7. Keep the underside of the mower deck clean. Remove   all grass and dirt buildup from the underside of the pan,   the baffles and deflectors after each use. Never, under   any circumstances, should you place hands or feet   under the mower deck or in the chute while blades or   impeller are still turning.   8. Alternate mower direction. This will evenly disperse the   mulched grass clippings over the lawn for even   fertilization.   If the mulching quality of the mower does not seem   to be satisfactory, try one or more of the following   tips:   • • • • Raise the height-of-cut setting on your mower.   It may be necessary to cut your grass more frequently.   Operate the mower at a slower ground speed.   Overlap cutting swaths instead of cutting a full swath with   each pass.   • • Mow across the marginal areas a second time.   CUT HIGH - MOW OFTEN!   29   Download from Www.Somanuals.com.

Read and follow the installation instructions that are   included with your grass catcher.   2. Set engine speed control to the wide open or full setting.   3. Do not attempt to cut grass when it is wet. Wet grass will   clog both the underside of the deck and the attachment   chutes. Empty bags often to prevent plugging.   4. If the grass is tall, place the mower deck cut height   selector in the top or second notch. “Initially” overlap   cutting swaths instead of a full swath with each pass.   5. Keep the underside of the mower deck clean. Frequent   removal of dried grass and dirt will greatly assist in   bagging of the clippings. Never, under any   circumstances, should you place hands or feet under   the mower deck or in the chute while blades or   impeller are still turning.   6. Operate the mower at a slower ground speed than when   mowing without a grass catching attachment.   30   Download from Www.Somanuals.com. All Manuals Search And Download.   OPERATION INSTRUCTIONS   MOWING WITH A   GRASS CATCHER ATTACHMENT (continued)   7. Maintain sharp blades throughout the cutting season.   Some grass catching attachments require a “high-lift”   blade. See your dealer for advice on the type of blade(s)   needed for your mower.   8. Some mowing applications/use of grass catchers may   require that an additional weight kit be fitted to the mower   to counter the weight of grass in the bags. Please consult   with your dealer for more information regarding   installation and adding weight to the box.   Failure to observe the following instructions   could result in personal injury.   WARNING   ! • • • • Watch for low hanging branches or other obstacles which   might hit the catcher top while turning or backing the   mower.   Use care when backing to avoid pushing the grass bags   into the frame or “hot” exhaust muffler of the engine. Fire   could result.   Disengage blade and stop engine prior to clearing grass   from either the discharge chute or grass catcher   components.   Do not operate the mower with the grass catching   attachment partially removed. Operator or bystanders   could be injured by thrown objects.   • • Keep all attachment bolts tight.   Important: Do not leave clippings in the bags while the   mower is stored. Damp grass clippings are a fire hazard if   left in the bag.   31   Download from Www.Somanuals.com.

Additional information can be found in the   Troubleshooting guide on Page 44-45.   To avoid personal injury, be sure that the   deflector is properly installed on the   discharge chute.   CAUTION   ! 1. Set engine speed control to the wide open or full setting.   2. Do not attempt to cut grass when it is wet. Wet grass will   clog the underside of the deck and discharge area.   3. If the grass is tall, place the mower deck cut height lever   in the top or second notch. “Initially” overlap cutting   swaths instead of a full swath with each pass. Some   applications may require a second cutting.   4. Keep the underside of the mower deck clean. Frequent   removal of dried grass and dirt will allow the clippings to   discharge correctly. Never, under any circumstances,   should you place hands or feet under the mower deck   or in the chute while blades or impeller are still   turning.   5. Maintain sharp blade(s) throughout the cutting season.   32   Download from Www.Somanuals.com.

Some applications   may require a second cutting.   Keep the underside of the mower deck clean.   Maintain sharp blades throughout the cutting season.   As a rule of thumb, never cut off more than one third of the   total grass blade length. Correct mowing height can reduce   weeds and disease by 50% to 80%.   The following grass cut heights are based on adequate   moisture conditions and normal thatch buildup in a healthy   lawn. Some locations and applications may require slightly   different cut heights. If in doubt, consult your local lawn   professional for assistance.   Grass Types   Bermudagrass   Bluegrass   Buffalograss   Ryegrass   Best Cut Heights   1 - 2" (25-51 mm)   2 - 3" (51-76 mm)   1½ -3" (38-76 mm)   2 - 3" (51-76 mm)   3-3½" (76-89 mm)   1 - 3" (25-76 mm)   Tall Fescue   Zoysiagrass   33   Download from Www.Somanuals.com.
