Establishing a Setting Rate
Step 1:
Use Chart 1 to estimate the number of LBS/1,000 square feet of coverage
(Example: 20LB bag with 10,000 square foot
coverage = 2.0LBS/1,000 square feet)
Step 2:
Find the closest LBS/1,000 square feet in Chart 2 that you estimated using Chart 1
(Example: 2.0LBS/1,000 square
feet = Spreader Setting of 13)

The settings furnished on the Rate Setting Matrix are intended as a guide only.
Variations in physical characteristics of material applied, walking speed, and
roughness of ground surface may require slightly different spreader settings. Due
to the above conditions, the Manufacturer makes no warranty as to the uniformity
of coverage actually obtained from the settings listed.
