Transport Operation

To begin transport operation, raise the aerator and
disengage the PTO. To avoid loss of control, traverse

steep inclines slowly, approach rough areas at
or Figure reduced speed and cross severe undulations carefully.
Important:
24 km/h (15 mph).

After Operation Safety

•
Keep all parts of the machine in good working
condition and all hardware tightened.
•
Replace all worn, damaged, or missing decals.
Inspection and Cleanup
after Use
After daily use, thoroughly wash the machine with a
g024284
garden hose without a nozzle to avoid contamination
and seal and bearing damage due to excessive
water pressure. You can use a brush to remove
accumulated material. Use mild detergent to clean the
covers. After cleaning, grease all drive lines and roller
bearings, inspect for machine damage, oil leakage,
and component and tine wear. Do not oil the O-ring
drive chain.
Remove, clean, and oil the tines. Spray a light oil mist
on the coring head bearings (crank and damper links).
Clean and coat the springs with a dry lubricant like
graphite or silicone.

Operating Tips

•
Carry replacement tines, spring wires, springs and
tools in case tines are damaged due to contact
with foreign materials.
•
Engage the PTO at low engine speed. Increase
the engine speed to achieve the desired PTO
g024285
speed of 400 to 460 rpm (maximum) and lower the
aerator. Operate at an engine speed at which the
aerator runs most smoothly.
Note:
particular tractor gear (or fixed hydrostatic pedal
position on tractors with hydrostatic transmission)
does not change the hole spacing.
•
Make very gradual turns when aerating. Never
make sharp turns with PTO drive engaged. Plan
(Figure
your aeration path before lowering the aerator.
Making sharp turns while aerating will damage the
aerator and the tines.
•
If the tractor bogs down when operating on hard
ground or going uphill, raise the aerator slightly
until speed is regained, then lower the aerator
again.
•
Best results are achieved when the tine entry is
on a slight incline toward the rear of the machine.
Use caution when extending the hydraulic top
