2.
Remove the lynch pins used to secure the driver and
driven gears.
3.
Install driver and driven gears matching indicated
chart time and secure with lynch pin.
CAUTION: Do not leave machine unattended and
to avoid personal injury do not work on machine
while it is running.
VERIFY TIMING BETWEEN THE
TRACTOR AND AERATOR
1.
Raise aerator, set parking brake, stop engine and
lower safety/transport stops.
2.
With transmission in correct gear selection,
lower and operate the aerator a short distance,
then raise aerator, disengage PTO and stop trac-
tor. Set parking brake.
IMPORTANT: Never operate the tractor
PTO in excess of 540 rpm or damage to the
aerator could occur.
3.
In direction of machine travel, measure the dis-
tance between tine holes (one tine penetration
stroke to another). Depending on tine selection,
the distance should be:
2.2 cm tines–14.6 to 15.2 cm.
7.3 cm tines–7.3 to 7.62 cm
Note: Condition of the turf around the holes can
also indicate how well the tractor speed is
matched to the aerator. If the rear of the tine
holes are torn, the tractor speed is too slow. If
the front of the tine holes are torn, the tractor
speed is too fast.
4.
If the spacing is too short (coring speed too
fast), increase the hole spacing; substitute the
driver gear with a gear having less teeth and the
driven gear with one having more teeth. If hole
spacing is too long (coring speed too slow), dri-
Operation
Note: Number of gear teeth is stamped on the
gear.
4.
Install gear case cover and lower aerator cover.
Verify timing of the aerator/tractor.
TRAINING PERIOD
Before using the aerator, find a clear area to practice using
the machine. Operate the tractor at recommended gear set-
ting and PTO speed and become thoroughly familiar with
machine handling. Practice stopping and starting, raising
and lowering the aerator, disengaging the PTO and aligning
the machine with previous passes. A practice session
assures confidence in the performance of the aerator and
helps ensure use of proper operating techniques wherever
the machine is operated.
To prevent turf damage, always make sure tractor is moving
and PTO is engaged when raising or lowering the aerator.
When aerating, three point lift system to be in “FLOAT”
position.
BEFORE AERATING
Make sure the hydraulic hose is clear of tractor and
machine components to avoid damage, and all safety shields
are secured in place. Inspect the area of operation for haz-
ards that could damage the machine and remove them, if
possible, or plan how to avoid them. Carry replacement
tines and tools to effect repairs should tines contact foreign
materials.
To avoid personal injury, never leave the tractor seat
without first setting the parking brake and disengaging
the PTO. Nver perform aerator repairs without first low-
ering the aerator onto transport/safety stops. Be sure all
safety devices are secured in the correct place before
resuming operation.
