To increase the depth of plugger point penetration, up
to 160 lbs. of weight may be added to the tray. Suitcase
type weights (1) can be attached to the center weight
bracket, or concrete blocks (2) or other weights may
be tied or strapped to the top of the tray. Before adding
weight, the plugger should be attached to tow vehicle
and lowered to the ground. See figure 8.
OPERATION
BEFORE sTARTING
•
•
Mow the lawn and remove all loose clippings prior to
use of the aerator.
If the soil is extremely hard and dry, it is recommended
that it be sprinkled or watered down for one or two hours
prior to aerating.
NOTE: Weights must be purchased separately.

HOw TO UsEYOUR PLUG AERATOR
Aerating pulls small soil plugs, ranging up to three inches
in length, from the soil to create small reservoirs that will
bring oxygen, fertilizer and water down into the roots. For
best aerator performance, the following lawn preparations
and operating procedures are recommended.
•
Start vehicle in low gear and more forward at slow
speed and then lower aerator. Increase speed only as
conditions permit.
MAINTENANCE
•
•
•
Check for and tighten any loose hardware before each
use.
•
•
•
•
Aerateinthestraightestlinepossible,makingoverlapping
passes to increase the plugger point pattern.
Avoid extremely sharp turns with plugger points
engaged in ground to prevent damage to lawn.
DO NOT cross over walks or drives without first raising
the aerator to the transport position.
On sloped lawns, always aerate in an up and down
direction. DO NOT attempt to follow the contour of the
ground.
Lubricate spool assemblies with grease at least once
each season.
Pluggerpointscanperiodicallybesharpenedwithasmall
grinder to maintain good penetration. Points should be
removed to sharpen. Follow original angle and contour
of points when grinding.
•
•
DO NOT attempt to aerate if ground is too wet, or
muddy.
•
•
Clean aerator and store in a dry area when not in
use.
Due to possible small rocks and gravel which can be
presentinaeratedsoilplugs, itisrecommendedthatthe
plugs be raked; otherwise damage to the lawn mower
blades may arise, especially when reel type mowers
are used.
Clean off dirt and rust and coat exposed metal with light
oil or touch up paint before storage.
