4.13 RECOMMENDATIONS FOR MOWING

1. Keep the mower deck and discharge chute clean.

2. Mow with sharp blades. A dull blade will tear grass,

resulting in poor lawn appearance and takes extra

power (slow mowing speed).

3. The discharge deflector must not be removed and must

be kept in the lowest position to deflect grass clippings

and thrown objects downward. Orient the side dis-

charge away from sidewalks or street to minimize

cleanup of clippings. When mowing close to obstacles,

orient the discharge away from obstacles to reduce the

chance of property damage by thrown objects.

4. Cut grass when it is dry and not too tall. Mow

frequently and do not cut grass too short (cut off 1/3

or less of existing grass for best appearance).

5. Operate the engine at or near full throttle for best

cutting. Mowing with a lower RPM causes the mower

to not cut clean and tear the grass. The engine is

designed to be operated at full speed.

6. Use slow travel speed for trimming purposes.

7. When mowing tall or wet grass, mow the grass twice.

Raise the mower to the highest setting for the first pass

and then make a second cutting pass to the desired

height.

8. Be sure the mower is leveled properly for a smooth

cut. See Section 7, Adjustments.

9. Use alternate stripe mowing pattern for best appear-

ance and vary the direction of the stripe each time the

grass is mowed to avoid wear patterns in the grass.

4.14 ADJUSTING CUTTING HEIGHT

The mower deck height switch on the instrument panel is

used to adjust the cutting height of the deck. Do not adjust

the cutting height while the mower is moving. Stop the

mower, then activate the deck height switch to position the

deck at the desired height. A gauge is located on the right

front of the mower (See Figure 4-11) for use in selecting

the proper cutting height.

-IMPORTANT-

Do not wash a hot or running engine. Use

compressed air to clean the engine and the

radiator fins. Cold water will damage the

engine and/or radiator.

4. Keep the entire mower clean to inhibit serious heat

damage to the engine or hydraulic oil circuit.

5. Recheck the cutter drive belts for proper tension,

alignment and any signs of rubbing. Correct and adjust

as necessary.

6. Fill the fuel tank with fresh, clean fuel at the end of

every day of operation.

7. Check the tire pressure. Inflate tires if necessary.

4.12 MOVING MOWER WITH THE ENGINE
STOPPED

To free-wheel or move the mower around without the

engine running, rotate the dump valve handle (screw and

nut) located on the side of the hydraulic pump to full open

position. See Figure 4-10. Disengage the parking brake

and move the mower by hand. The lever must be returned

to the original position to operate the mower.
