A
BEFORE USING YOUR AERATOR
* DO NOT attempt to aerate if ground is muddy.
*» If ground is extremely hard or dry, it is recommended
that it be watered down for 1 or 2 hours prior to use.
using the aerator.
<* Mow lawn and remove loose clippings prior to use of
lawn aerator.
* Attach the aerator to the tractor hitch and check to see
that the aerator is level. Adjust by loosening the bolts
which fasten the hitch mount arms to the hitch arm
mount brackets. Raise or lower the position of the
arms until the aerator is level. See figure 8.
HOW TO USE YOUR AERATOR
Aerating cuts small holes in the soil to create reservoirs
that bring oxygen, fertilizer and water into the root zone.
For best performance of the spike aerator attachment, the
following lawn preparation and operation is recommended.
* Start tractor engine with controls in neutral and place
throttle at slow engine speed.
* Engage shift lever into lowest possible fonward speed
and increase speed as conditions permit.
Aerate in the straightest line possible, making over
lapping passes to increase spike point pattern.
To prevent lawn damage, avoid sharp turns.
On sloped lawns aerate in up and down direction.
DO NOT aerate across the face of slopes.
To increase spike point depth penetration add weight
as required. The aerator frame holds up to three
concrete blocks at approximately 35 pounds each.
Weights can be secured to frame with straps or
other binding material. See figure 8.
