Aerating Procedures - Toro AERATOR HC 4000 Operator's Manual

ver gear teeth quantity should be increased and driven gear
teeth decreased; see gear selection chart.
5. Operate the machine again and repeat steps 1–4.
IMPORTANT: Timing can sometimes be fine tuned by gradu-
ally regulating tractor tire pressure. Lowering tire pressure
will provide closer spacing and raising tire pressure will
increase the spacing.
CAUTION: Do not exceed the maximum or minimum inflation
pressures as recommended by tire manufacturer.

AERATING PROCEDURES

When the tractor reaches proper ground speed, lower the aerator.
The aerator can be operated in slight curves, but for best results
operate in a straight line. If the machine must be turned sharply,
raise the aerator and disengage the PTO. Otherwise, severe turf
damage will result and the machine may also be damaged.
Look behind frequently to ensure the machine is operating proper-
ly and alignment is maintained with previous passes.
Should the driveline ratchet during operation:
1. Raise the aerator, disengage the PTO and stop immediately.
2. Set the parking brake, lower aerator onto safety/transport
stops.
3. Inspect the turf to determine the reason for the ratcheting or
tine breakage. Locate where the problem occurred and insert a
non-conductive probe into the aerator holes. If foreign materi-
al beneath the turf caused the damage, mark the location so
the material can be either removed or avoided in future. If the
ratcheting occurred because turf was too hard to penetrate,
raise depth of penetration and try aerating the area again. Be
sure all machine damage has been corrected before resuming
operation; refer to step 5.
4. Always clear the area of all damaged machine parts, such as
broken tines, etc., to prevent their being picked up by mowers
or other turf maintenance equipment.
5. Replace broken tines, and inspect and correct damage to those
still useable. Repair any other machine damage before com-
mencing operation.
