When servicing the electric wiring, stop the engine without fail. Otherwise your hands or clothes may be caught in or sandwiched between rotating parts.

(2)

Before manipulating electric parts, be sure to disconnect the earth battery cable (-), or you may get an electric shock or be injured by sparks.

(3)

Loose electric terminals or connectors may not only lower electrical performance but also cause short circuit or leakage of electricity, which may lead to a fire. Promptly repair or replace damaged wiring.

(4)

FIG. 11

Remove chaff or dust from the battery, wiring, muffler or engine. Otherwise it could result a fire.

10.2. TO HANDLE THE BATTERY (1)

When working around the battery, avoid smoking.

The battery generates explosive hydrogen and oxygen gases when it is being charged. Keep the battery away from sparks or open flames.

(2) The battery should be inspected before starting the engine. Be careful not to touch the electrolyte makes contact with the skin or clothing, wash it off immediately with water and then consult a doctor.

FIG. 12

(3) When replacing or inspection the battery stop the engine and turn the main switch off, or electrical parts may be damaged or unexpected accident may occur.

(4) When disconnecting the battery cables, disconnect the earth cable (-) first without fail. When connecting the battery cables, connect the positive cable (+) first. Disconnecting or connecting in wrong order may lead to a short circuit or sparks.

10.3. TO HANDLE BOOSTER CABLES When using booster cables, pay attention to the following items for safe operation: (1) Before connecting cables, remove the vent plugs.

This will lower the force in case of explosion.

(2) Before connecting cables, be sure to stop the engines.

Otherwise unexpected accidents may occur.

(3) Use booster cables with sufficient electrical capacity. A cable of inadequate capacity will cause generation of heat, which may lead to a fire.

FIG. 13 (1) Negative cord

(2) Positive cord

CHAPTER 1. FOR SAFE OPERATION 11. TYRES AND WHEELS 11.1. Be sure to keep tyre pressures at the levels specified in this manual. Excessively high tyre pressure may result in explosion, which may lead to physical accidents.

11.2. If a cut is found in a tyre and the cut reaches the cords, do not use it. Such a tyre may explode.

11.3. Before replacing or repairing tyres, tubes, or rims, consult your dealers ahead of time. Such operation should be performed by trained mechanics.

12. BEFORE STORING THE ZERO TURN MOWER 12.1. After operation, be sure to close the fuel cock to prevent fuel from spilling, as spilled fuel may catch fire.

FIG. 14

12.2. Never allow grass or leaves to accumulate around heated parts such as the engine and the muffler, or this may cause a fire.

12.3. Be sure to remove the ignition key to prevent unexpected accidents caused by engine starting by untrained persons or children.

12.4. When storing the Zero turn mower with the mower deck attached, be sure to lower the mower deck on the ground. Otherwise manipulation of the lift lever by untrained person or children may cause unexpected accidents.

12.5. Store the Zero turn mower in a place provided with sufficient illumination. Inspection and moving of the Zero turn mower in a dark place may lead to unexpected accidents.

12.6. When the Zero turn mower is to be stored in a closed place like a garage or a barn, provide sufficient ventilation for exhaust gases. Exhaust fumes can be lethal.

12.7. To avoid fire hazard, keep the engine, muffler, battery, and fuel storage area free of grass, leaves, or excessive grease.

12.8. Never cover a hot Zero turn mower just after operation with a tarpaulin or the like, or the heated engine and related parts may cause a fire.

23

SZ330 13. LONG TERM STORAGE 13.1. Never store the mower with fuel in the tank inside a building where fumes can reach an open flame or spark.

13.2. Lower the cutting unit(s) when you store the front mower, unless you lock the cutting unit(s) into position.

13.3. Allow the engine to cool before storing the front mower in any enclosure.

13.4. Before storing the Zero turn mower for a long period of time, disconnect the battery cables to prevent them, in case they are gnaw by rats, from causing a short circuit, which may lead to a fire. When disconnecting the battery, disconnect the negative (-) cable first, while connecting the positive (+) cable first when connecting the battery. Wrong order of disconnecting or connecting the battery will cause sparks, which is very dangerous.

CHAPTER 4. MOWER OPERATION WARNING: • As soon as the PTO switch is turned to the ON ( ) position, the mower blades start rotating and eject cut grass or stones through the discharge opening. Consequently, before operating the PTO switch make sure that there is no people, animals, or physical properties like buildings, cars, etc. within a range where ejected grass or stones may reach.

• The mower blades should be turned only on turf or grassland with the mower deck lowered.

CAUTION: Park the zero turn mower on level, hard ground and make sure that the parking brakes are applied securely. d. Turn the PTO switch to the STOP (

) position.

e. Turn the key switch to the STOP ( the engine.

) position to stop

• •

h. Shift the throttle lever to the high speed position ( to raise engine speed.

)

i. As the drive control levers are pushed gradually, the Zero turn mower starts to travel.

f. Remove the starter key and cap the key hole without fail.

CAUTION: Be sure to start mowing at sufficiently low speeds and increase travelling speed gradually.

CAUTION: When you leave the zero turn mower, be sure to stop the engine and remove the starter key to prevent the zero turn mower from being started unexpectedly by children or unauthorized people.

IMPORTANT: The engine hood and the radiator screen should be kept clean. Never keep on operating with clogged screens, or the engine may be overheated, which may result in engine seizure.

IMPORTANT:Be sure to cap the key hole after having removed the starter key. Otherwise, water or dust may enter into the switch, which may cause trouble.

4. EMERGENCY STOP •

•

•

IMPORTANT: Never attempt to stop the engine abruptly when it is running at high speeds.

Be sure to let the engine idle for about 5 minutes after long operation and then stop the engine. Abrupt engine stopping may lead to overheating causing seizure.

When any of the following abnormalities is encountered, stop the zero turn mower and mower deck immediately.

- Abnormal noise - Abnormal vibration - Abnormal smell - Blade hitting an obstacle - The zero turn mower hitting an obstacle The cause of trouble should be located and corrected immediately. If not, consult your dealers.

Never attempt to keep on operating the zero turn mower without locating and correcting the cause of trouble.

When leaving the zero turn mower to remove obstacles such as twigs, pebbles, etc., the PTO switch must ) position and the parking be turned to the OFF ( brake applied.

5. STOPPING MOWING OPERATION a. Release the dive control levers and shift to lock position. b. Shift the throttle lever to the low speed position ( ) to reduce engine speeds. c. Apply the parking brake.

85

SSM60 & SSM72 (SZ330) 6. EFFICIENT MOWING

c. For mowing low moisture content grass or when there is much dead grass

IMPORTANT: • Be sure to mow at full throttle ( ).

• Choose an adequate traveling speed in accordance with the height or other conditions of grass to be cut.

• When the screens for the air-intake openings and radiator are clogged with dust, clean them at once. Never go on operating with clogged screens.

• Mowing is desirable when the grass is dew-free: in the afternoon or late afternoon, thus preventing the mower from heavy clogging.

• Always keep the mower deck clean.

• Check the blade ends for damage.

• Repeated mowing is recommended before the grass grows to high.

• Cutting grass too closely may damage the grass.

To maintain a green lawn, never mow more than onethird off the height of the grass in one mowing.

•

• •

i. Advance should be in a direction where the dust does not hit the operator by taking into consideration the direction of the wind. ii. When the air-intake screens are clogged, clean them at once.

IMPORTANT: • When operating the zero turn mower in dusty circumstances, keep on paying attention to the coolant temperature warning lamp with buzzer.

• Never continue operating when screens are clogged, or engine breakdown may result.

A slower travelling speed will result in improved mowing. Avoid selecting such a travelling speed that causes the zero turn mower to bounce.

Short, fast turns will damage turf. Slow down sufficiently when turning.

Frequent sharpening of the mower blades results in beautiful finish and less load on equipment, which leads to economical operation.

a. For mowing tall grass i. Mow grass twice.

First, mow the grass to a height to make it low enough for the next finishing pass. Then finish to the desired grass height.

The second travelling pass should be shifted side ways by 20 cm (8 in.) or so, or travel perpendicular to the first passes, which will result in a beautiful even finish. ii. When trying to finish in one pass, select a sufficiently slow travelling speed. It may also be required to set the cutting width to half or one-third of that for normal operation. b. For mowing highly moist grass or on wet ground i. If turf damage by the tyres could result, wait until the grass and land have dried sufficiently. ii. Wet grass requires a higher grass cutting height setting than when mowing dry grass, as the cutting height is often lower than expected during operation. iii. Select a sufficiently slow travelling speed and avoid sudden starts, turns, and stops. If not, the turf may be damaged.

86

CHAPTER 5. INSPECTION AND MAINTENANCE OF MAJOR PARTS

CHAPTER 5. INSPECTION AND MAINTENANCE OF MAJOR PARTS CAUTION: • When servicing the zero turn mower, place it on level, hard ground.

• Stop the engine and remove the starter key.

• Apply the parking brake securely.

• Shift the lift lever to down position ( ) to lower the mower to the ground.

• Turn the PTO switch to the STOP position ( ).

CHAPTER 5. INSPECTION AND MAINTENANCE OF MAJOR PARTS 3. INSPECTION & REPLACEMENT OF BLADES

1

3.1. BLADE REMOVAL CAUTION: Be sure to wear gloves to avoid cuts by blades.

Block blades by inserting a piece of wood,1, between blade and mower deck. Loosen blade retaining nut with a 27-mm box end wrench. As blades are tightened with washers and shims, take care not to lose them when blades are disassembled.

FIG. 107 (1) Wood

3.2. SHIMMING OF BLADES

2

Tighten blade nuts temporarily to determine the height difference between blades. If more than 0.04" (1mm), correct with adjusting shims,2, Excessive difference in blade positioning will result in poor mowing finish.

FIG. 108 (2) Shims Blade nuts,3, should be tightened to a torque of 94 ft.lbs.

(1300 kgf･cm).

3

IMPORTANT: • If the blade ends have become round due to wear, enlarged clearance between blades leave uncut grass behind. The blade should be checked timely and worn ones should be replaced immediately.

• Low cutting height or the operation just after soil has been applied will wear blades rapidly. The blades should be checked more frequently. a. New Blade

FIG. 109 (3) Nut

b. Blade with rounded edge c. Excessively worm blades are very dangerous. So replace such blades with new ones at once.

CAUTION: When sharpening blade edges, both ends should be done in same manner or blade becomes unbalanced.

Pass a rod through blade center hole and check to see if blade is balanced properly. If balance is improper, correct it. Unbalanced blades will cause excessive vibration.
