Spread Pattern
Determining Driving Centers
Once an acceptable pattern is obtained, as shown in Figure 5, driving centers can be determined� To
determine optimum driving centers (effective swath width), determine the average amount of material
in the center of the pattern. Figure 8 shows an example data sheet recorded from the profile shown in
Figure 9� Based on the example, the average amount of material in the center of the pattern is 3�0, as
indicated with the red dotted line�
Next, locate the points on both the left and right side of the pattern where the amount of material is
half the average amount at the center of the pattern� In the example shown in Figure 8, these points are
located 45’ to the left of center, and 45’ to the right of center� The distance between these two points
(90’) represents the driving centers to use�
NOTE: Once the effective swath width has been established, a change in the controller may be required�
