*Perform the following steps in sequence to assure

secure locking of the lift handle.

a. Turn the aerator upright, then place the lift handle

into the transport locking notch at the front end of

the slot in the tray.

b. Stand on the right side of the aerator and push

against the tray, which will force the lift handle over

to the right side of the notch.

c. Keep the tray and lift handle in this alignment and

tighten the eight bolts at the corners of the tray.

d. Tighten the two bolts which fasten the middle

brace to the tray.

e. After performing these steps, some effort should

be required to shift the lift handle from the trans-

port locking notch over into the slot to lower the

aerator. When the aerator is raised, the lift handle

should spring back over into the transport locking

notch.

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.

CAUTION: POINTS OF AERATOR

KNIVES ARE SHARP! EXERCISE

CAUTION AT ALL TIMES WHILE

USING THE AERATOR.

CAUTION: TO PREVENT INJURY,

DISMOUNT FROM TRACTOR TO

RAISE OR LOWER AERATOR

CONTAiNiNG ADDED WEIGHT.

• Mow lawn and remove loose clippings prior to use of

lawn aerator.

Start tractor engine with controls in neutral and place

throttle at slow engine speed.

Engage shift lever at lowest possible forward speed

and lower aerator, allowing plugger points to enter the

ground. Increase speed as conditions permit.

Aerate in the straightest line possible, making

overlapping 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.

To increase the depth of plugger point penetration,

up to 140 Ibs. 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.

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.

DO NOT attempt to aerate if ground is too wet,

(muddy).

Do to small rocks and gravel which are normally

present in aerated soil plugs, it is recommended that

the plugs be raked; otherwise damage to the lawn

mower blades may arise, especially when reel type

mowers are used.

Plugger points can periodically be sharpened with a

small grinder to maintain good penetration. Points

should be removed to sharpen. Follow original angle

and contour of points when grinding.

For storage, clean the aerator and lightly oil all

exposed metal parts to prevent rust.

Oil the spool assemblies and shaft as needed.

Oil the wheel hubs as needed.
