Operating Tips; Lubrication; Greasing Bearings And Bushings - Toro AERATOR HC 4000 Operator's Manual

OPERATING TIPS

1. Gradually engage PTO at low engine speed and throttle up to
540 PTO RPM before lowering aerator.
2. Make very gradual turns when aerating. Never make sharp
turns.
3. If tractor "bogs" down when operating on hard ground or going
uphill, raise aerator slightly until speed is regained, then lower
again.
4. Do not aerate if ground is too hard or dry. Best results are
obtained after a rain or when turf has been watered the previ-
ous day.
5. Raise coring head penetration, if ground is hard packed. Clean-
up cores and re-aerate at deeper penetration, preferably after
watering.
6. Store aerator on stand provided whenever it is removed from
tractor.

Lubrication

GREASING BEARINGS AND BUSHINGS

The HC 4000 Aerator has grease fittings that must be lubricated
regularly with No. 2 General Purpose Lithium Base Grease. If
machine is operated under normal conditions, lubricate bearings and
bushings after every 25 hours of operation or prior to storage.
Grease stomper arm bearings daily.
The lubrication points are: Cylinder pivot-upper (2) (Fig. 5);
Cylinder pivot-lower (2), stabilizer bar (4), trailing arm (4), finger
plate pivot linkage (4) (Fig. 6); Gear box support tube (1), stomper
assy. (4), gear box couplings (2) (Fig. 7); castor wheel bearings and
pivot shaft mount (4), trailing arm (2), roller (2) (Fig. 8); Trunnion
adjuster (2) (Fig. 9) and Drive line (5) (Fig. 10).
1. Wipe grease fitting clean so foreign matter cannot be forced
into the bearing or bushing.
2. Pump grease into the bearing or bushing.
3. Wipe up excess grease.
