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.
