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.
