DETERMINE THE TOTAL SURFACE AREA<br />
AFFECTED AND AMOUNT OF MATERIAL REMOVED.<br />
TINE SELECTION GUIDE<br />
STEP ONE<br />
The first step is to find holes per square foot.<br />
If you know your lateral and forward spacing, find holes<br />
per square foot on the Holes Per Square Metre table.<br />
Example:<br />
Lateral Spacing = 5.1 cm<br />
Forward Spacing = 5.1 cm<br />
Holes Per Square Metre = 384.5<br />
If you are not sure of your forward and lateral spacing, but know your aerator model<br />
number go to the Pick A Model table and pick your spacing options. This table will also<br />
help you determine the proper turf holder based on your tine configuration.<br />
STEP TWO<br />
To determine the total surface area affected and volume of soil removed when aerating,<br />
reference the Percent Surface Area Affected/Volume Removed table. All you need to<br />
know is holes per square metre, core diameter (ID), and the depth* at which you are<br />
aerating.<br />
Example:<br />
Holes Per Square Metre = 384.5<br />
Core Diameter = 0.8 cm<br />
Depth = 7.6 cm<br />
Percent Surface Area Affected = 1.79%<br />
Volume Removed = 0.133 cubicmetres per 100 square metres<br />
* Tine depth can vary based on machine set-up.<br />
