WHEELS AND TIRES

Torque Wheel Nuts
After the first ten (10) hours operation, check the torque on
the wheel nuts and every 200 hours thereafter.
1. Torque the lug nuts for the front wheels 81–95 Nm.
2. Torque the lug nuts for the rear wheels to 41–47
Nm.

Check Tire Pressure

Since the Groundsmaster 580-D can be operated under
many different types of turf conditions, proper tire pressure
is very important. Check tire condition and pressure daily
and use the following guide to maintain maximum turf
conditions:
Under normal mowing conditions and when used on a
wide variety of turf grasses—103.4 kPa front; 89.6 kPa rear.
344.7 kPa Casters.
When turf is wet and softer than normal—use low tire
pressure: 82.7 kPa front and 62 kPa rear.
When turf is dry and harder than normal, use high pressure:
124 kPa front and rear.
IMPORTANT: Do not operate in HIGH RANGE for
extended periods when tire pressure is less than 138 kPa
because tires may be damaged. When tire pressure
exceeds 138 kPa, HIGH RANGE may be used.

CUTTING UNIT LUBRICATION
Follow guidelines in the Lubrication Chart to properly
maintain the units. To gain access to the center and inner
spindle shaft fittings on each outboard unit, proceed as
follows:
Note: To grease spindle bearings, apply 2–3 pumps with a
hand grease gun for each spindle.
1. Position the machine on a level surface, lower the
cutting units to the shop floor, engage the parking
brake, shut the engine off and remove the key from
the ignition switch.
2. Remove the inner deck pulley cover (Fig. 55).
1. Inner cover
3. Use the belt to rotate the inner and center spindle
pulleys until the grease fittings can be accessed with
a grease gun.
4. Grease the fittings and replace the cover.

BLADE MAINTENANCE

Note: Although not needed for normal maintenance
procedures, the front cutting unit can be pivoted (tilted) to a
fully upright position (Fig. 56). Should you desire to tilt the
cutting unit, proceed as follows:
