OPERATION  
MAINTENANCE  
Aerating means pulling 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.  
Forbestaeratorperformance,thefollowinglawnpreparations  
and operating procedures are recommended.  
1. Pluggerpointscanperiodicallybesharpenedwithasmall  
grinder to maintain good penetration. Points should be  
removed to sharpen. Follow original angle and contour  
of points when grinding.  
2. For storage, clean the aerator and lightly oil all exposed  
metal parts to prevent rust.  
CAUTION: POINTS OF AERATOR  
KNIVES ARE SHARP! EXERCISE  
CAUTION AT ALL TIMES WHILE  
USING THE AERATOR.  
LUBRICATION  
1. Mow lawn and remove loose clippings prior to use of  
lawn aerator.  
2. Start tractor engine with controls in neutral and place  
throttle at slow engine speed.  
1. Oil the spool assemblies and shaft as needed.  
2. Oil the wheel hubs as needed.  
3. Engage shift lever at lowest possible forward speed  
and lower aerator, allowing plugger points to enter the  
ground. Increase speed as conditions permit.  
4. Aerateinthestraightestlinepossible,makingoverlapping  
passes to increase the plugger point pattern.  
5. Avoid extremely sharp turns with plugger points  
engaged in ground to prevent damage to lawn.  
6. DO NOT cross over walks or drives without first raising  
the aerator to the transport position.  
7. On sloped lawns, always aerate in an up and down  
direction. DO NOT attempt to follow the contour of the  
ground.  
8. To increase the depth of plugger point penetration,  
up to 140 lbs. of weight, such as bags of sand or (4)  
concrete blocks, may be added to the tray. The weight  
can be secured to the tray with ties or straps fastened  
to the front and rear of the tray. Fasten so that the ties  
or straps cannot become entangled on rotating parts.  
10. Ifthegroundisextremelyhardanddry,itisrecommended  
that it be sprinkled or watered down for one or two hours
