EFFECTIVE SWATH WIDTH
There are basically three acceptable spread patterns, the flat top, pyramid and oval. With the
correct swath spacing, all of these will give a uniform rate of application throughout a field
(Diagram D).

When one of these patterns is obtained, further adjustment is unnecessary and the effective swath
width can be determined.
The effective swath width is the interval that a particular spreader should be driven to obtain
uniform application. Driving at an interval other than an effective swath width will result in a
non-uniform application (Diagram B). The effective swath width will vary with the type of
material being spread and the rate per acre it is applied. Spread pattern checks should be made
before different fertilizer materials are spread.
