Step 11: Adjust Handle & Tighten Connections
Place the aerator right side up its wheels, locking the lift handle into the oset at the front of the tray slot.
Perform the following steps to assure correct alignment of the light handle with the slot. Refer to Fig 11.
1. Adjust the tray side to side until the lift handle rests against the right side (viewed from the rear) of the oset
at the front of the slot.
2. Straighten the end plates and then tighten the eight bolts at the corners of the tray, making sure the lift
handle still rests against the right side of the slot oset.
3. Straighten the middle brace and tighten the two bolts which fasten it to the tongue.
Make sure the lift handle still rests against the right side of the slot oset. You should have to force the handle
over into alignment with the slot when lowering the aerator.
The licking device could help to prevent the handle be sliding out when the aerator in running. But if you
feel this device is not convenient, just take out the pin.

OPERATION 81.200.004
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.
For best aerator performance, the following lawn preparations and operating procedures are recommended.
MAINTENANCE
1. Plugger points can periodically be sharpened with a small grinder to maintain good pattern. 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.
LUBRICATE
1. Oil the spool assemblies and shaft as needed.
2. Oil the wheel as needed.
1. Mow lawn and remove loose clipping prior to use of lawn aerator.
2. Start tractor engine with controls in neutral and place throttle at slow engine speed.
3. Engage shaft lever at lowest possible forward speed and lower aerator, allowing plugger points to
enter the ground. Increase speed as conditions permit.
4. Aerate in the straightest line possible making overlapping 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 slopped lawns, always aerate in an up and down direction. DO NOT attempt to follow the corner of
the ground.
8. To increase the depth of plugger point penetration, up to 440lbs, 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.
9. If the ground is extremely hard and dry, it is recommended that it be sprinkled or watered down for one or
two hours prior to aerating.
10. DO NOT attempt to aerate if ground is too wet (muddy).
11. Do to small rocks and gravel which are normally present in aerated soil plugs, it is recommended that the
plugs be rakes; otherwise damage to the lawn mower blades may arise, especially when reel type mowers
are used.
CAUTION: Points of aerator knives are sharp! Exercise caution
at all times while assembling and using the aerator.
CAUTION: To prevent injury, dismount from tractor to
raise or lower aerator containing added weight.
