In some instances, angling the aerator forward may
improve hole quality but will also reduce aeration depth
and gain clearance with the turf guards. A forward angle
of approximately 4_ is a good initial setting. Use a
magnetic based angle indicator to determine the forward
angle, or use the following procedure:
A. Position aerator on a flat level surface.
B. Make sure aerator roller is on the ground and depth
indicator is set at desired setting (Fig. 22).
