HOW TO USE YOUR SPIKE AERATOR

Aerating means cutting small holes in the soil to create small reservoirs that will bring oxygen, fertilizer and water down into the root zone. For best performance of the spike aerator, the following preparation and operation is recommended.

&

CAUTION: Aerator points are sharp.

Be careful when servicing or operating the aerator.

Mow the lawn and remove loose clippings before using the aerator.

Drive to starting point with aerator in transport mode.

Lower aerator spikes by pulling the transport handles back.

Set the tractor throttle at slow speed and engage the shift lever in the lowest possible forward speed.

Increase speed as conditions permit.

Aerate in the straightest line possible, making overlapping passes to increase spike point pattern.

To avoid damage to your lawn, DO NOT TURN

SHARPLY with the spike points engaged in the ground.

On sloped lawns, aerate_n an up and down direction.

DO NOT attempt to follow the contourof the ground.

DO NOT attempt to aerate ifthe groundis too hard

and dry or if it istoo wet (muddy).

OPERATING TIPS

To increasespike point depth penetration, add weight

to the upper frame as required.rhe frame holds

three concreteblocks or patio blocks at approximately

35 Ibs.each. Secure the weightswith straps or wire,

usingthe holes in the shield flange. See figure 5 on this page.

• If the ground is extremely hard and dry, it is recommended that it be sprinkled or watered down for one to two hours prior to use of the aerator.
