When operating on a slope, shift the changeover lever to the 4WD position without fail.

IMPORTANT: ・ Be sure to shift the 4WD lever to the "AUTO" position when operating on level ground, as level ground operation with the 4WD selected leads to a larger turning radius and may cause turf damage.

・ W hen shifting the 4WD lever, slow down the travelling speed below 1 km/ h and make the machine go straight.

CAUTION: Park the front mower on flat, level ground and make sure that the parking brake is applied securely. In order to maximize the performance of the parking brake, depress the brake pedal, and then apply the parking brake. d. Shift the mower lift lever, 6, to DOWN position to lower the mower deck onto the ground.

CAUTION: When operating the front mower on a slope, be sure the 4WD lever is locked in the 4WD position from the reasons mentioned below:

CAUTION: When stopping the front mower, lower the mower deck onto the ground without fail to avoid unexpected accidents.

In the AUTO position the mechanism shifts to 2WD automatically when the peripheral speed of the front wheels exceeds that of the rear wheels, which means loss of rear wheel driving power.

For example, when moving uphill if the front wheels slip, the mechanism stays in 4WD. But moving downhill if the front wheels slip and lose grip, and begin to slip down the slope, it shifts to 2WD, that is, braking effect of the HST unit is lost, which means loss of front mower control.

21. BATTERY ■ INSPECTION OF BATTERY The battery (1) is installed on the middle of the left-hand side of the machine.

1

2

Check if the electrolyte level is between the upper and lower limits. If the level is below the lower limit, remove the battery, paying attention to the following points, and

3

FIG. 8-40 67

SF225, 237 replenish distilled water from the refill plug (2) to raise the level to the upper limit.

b. As the battery discharges even when it is not used, it should be charged every month or every other month at least.

・Be sure to connect the battery terminals correctly. ・ The wiring from the battery should be kept clean and connectors tight. Dirty or loose wiring may cause a fire. ・ W h e n d i s c o n n e c t i n g t h e b a t t e r y, d i s c o n n e c t the negative terminal first and vice versa when connecting.

c. W hen storing front mower for long period without operation, self-discharge of battery will happen (especially in winter). If the front mower is stored for more than 1 month, the battery minus terminal should be disconnected.

When operating for the first time or after long term storage, check if the battery charge level is enough. (If measurement of battery voltage is available, check if the voltage is more than 12.5V.) When the front mower is stored more than 6 months, charge the battery.

2 A

1

IMPORTANT: ・ Avoid quick charge of battery. Or it will shorten the service life of the battery.

・ When replacing the battery, use a battery of the same capacity as that of the current one

・ When using booster cables, take sufficient safety measures.

・ Do Not throw away the battery to the garbage can. Recycle it to follow the law of your community.

B

(1) Battery A: Upper limit

FIG. 8-42 (2) Filler plug B: Lower limit

22. WHEEL TIGHTENING BOLTS AND NUTS Check the wheel tightening bolts and nuts for looseness All bolts and nuts should be tightened to the specified torque.

WARNING: ・ T he battery generates very explosive gases, so avoid smoking and keep sparks and open flames away from the battery.

Charging the battery should be done in a place well ventilated to disperse explosive gasses as quickly as possible. ・ Battery electrolyte is very corrosive and will cause burns, so if it splashes on skin or clothes, wash it off immediately. If acid contacts eyes, flush immediately with clean water and get medical attention.

Specified tightening torque (Bolt): Front wheel: 45.1N･m ～ 57.9N･m

(460kgf･cm ～ 590kgf･cm) Rear wheel: 127.2N･m ～ 147.2N･m (1 298kgf･cm ～ 1 502kgf･cm) Tighten the bolts near the maximum level and tighten again so that the groove and hole aligned together, insert the cotter pin through the hole and groove, sprit the edge of it.

CAUTION: ・ N e v e r a t t e m p t t o k e e p o n u s i n g o r charging the battery with an electrolyte level lower than the limit, or the battery may explode or its service life be shortened due to deterioration inside the casing. ・ T he electrolyte level should always be kept between the upper and lower limits.

A too high level will cause the electrolyte to overflow and corrode other parts.

23. TIRE PRESSURE (INFLATION) Improper tire pressure causes abnormal wear of the tires and affects the front mower performance. Too high pressure causes the front mower to bounce too much and too low-pressure increases travelling resistance, which leads to power loss.

Tire pressure should be checked every day.

■ HANDLING OF THE BATTERY

Tire size Pressure Front: 23x10.5-12 140 kPa (1.4kgf/cm2) Rear: 18x8.5-8 154 kPa (1.54kgf/cm2)

a. As atmospheric temperature lowers, the performance of the battery also lowers. Consequently, the battery should be serviced with special care in wintertime.

68

CHAPTER 8. MAINTENANCE CAUTION: ・ Tire inflation should be set to the values specified in this manual. Excessive inflation may cause explode, which may result in serious accidents. ・ Insufficient pressure in the tires causes uneven tire wearing that can shorten tire lifetime. ・ W hen a tire, tube, or rim is required for replacement, ask your dealer. Such operation should be done by a trained mechanic especially for tire handing. ・ Never use a tire with a cut or crack which reaches tire cords as such a tire may explode.

1

FIG. 8-44

24. STEERING / TOE-IN Start the engine and turn the steering wheel lightly in both directions to check the wheel turns smoothly.

Make sure the tire toe-in is set properly. Inappropriate toe-in can result in abnormal tire wear and unstable tearing.

Toe-in: A-B = 2 to 6 mm (0.08 to 0.23 in.)

1

IMPORTANT: When any abnormality is found with the steering wheel or toe-in of the tires, ask your dealer to correct it.

SCMA54, SCMB60, SSM54 8. EFFICIENT MOWING

C. F or mowing low moist content grass or when there is a lot of dead grass a. D rive in a direction so that the dust does not hit the operator by taking the direction of the wind into consideration.

IMPORTANT ・Be sure to mow at full throttle.

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

・ When the radiator screen is 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, this preventing the mower from heavy clogging.

・Always keep the mower deck clean.

・Check the blade ends for damage.

・ R epeated mowing is recommended before the grass grows too high.

・ Cutting grass too short may damage the grass. To maintain a green lawn, never mow more than one-third off the height of the grass in one mowing.

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

・ Quick and fast turns will damage turf.

Slow down sufficiently when turning.

b. When the radiator screens are clogged, clean them at once.

IMPORTANT: ・ W hen operating the front mower in dusty circumstances, keep on paying attention to the coolant temperature warning lamp.

・ N e v e r c o n t i n u e o p e r a t i n g w h e n screens are clogged, or an engine breakdown may result.

9. FLIPPING UP OF MOWER DECK a. Fold up the left-hand side and right-hand side mirror ASSY. b. L ift up the mower deck in the highest position by shifting the mower lift lever. Separate the lift rod (1) by moving pin (2) and removing the hear pin (3) in the rear of the mower deck. Remove the chain of the universal joint.

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

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

T he second travelling pass should be shifted sideways by 20 cm or so, or travel perpendicular to the first passes, which will result in a beautiful even finish. b. 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.

FIG. 3-10

B. For mowing highly moist grass or mowing on wet ground a. If the turf could be damaged by the tires, wait until the grass and land have dried sufficiently.

c. L ift up the mower deck in the highest position by shifting the mower lift lever d. Lift up front side of mower deck, and then lock the mower deck by inserting the pin (use removed pin from the lift rod) into the hole.

b. 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 because the front mower sinks.

e. Swing the mower deck. Then insert the link pin of rear rod to the stopper on bracket of lift arm. This should be done on both sides.

c. Select a sufficiently slow travelling speed and avoid sudden starts, turns, and stops. If not, the turf may be damaged.

CAUTION: When swinging the mower deck, take care to prevent it from hitting you.
