SPREADER SETTING INSTRUCTIONS
FOR MATERIALS THAT USE A TYPICAL 5,000 Sq. Ft, 10,000 Sq. Ft. & 15,000 Sq. Ft. COVERAGE VALUE
See additional spreader setting instructions on the following pages if your material coverage value is not
typical.
To obtain the proper spreader setting for the material being spread, follow these steps:
1. Find the total weight in lbs. Of the product from the product label on the bag of material. Reference the
nearest corresponding row in Chart A.
2. Find the coverage amount in square feet that the product is rated for from the product label on the bag of
material. Reference the corresponding column in Chart A.
3. Find the nearest intersecting point of these two numbers from Chart A. (this number equals the lbs. per
1000 sq. ft.)
4. Use this number to find the nearest number in the column "lbs. / 1000 sq. ft." on Chart B to obtain the
spreader setting.
5. You may have to approximate your spreader setting based upon the lbs. per 1000 sq. ft. number that you
arrived at.
As an example:
1. The fertilizer bag weighs 42 lbs.
2. The coverage value is rated at 15,000 square feet.
3. Use Chart A to find the corresponding column of coverage and nearest row of weight. The nearest
intersecting point is approximately 2.8 since the bag weight is between 40 lbs. and 45 lbs.
4. Using Chart B, the number 2.8 is between 2 lbs. per 1000 sq. ft. and 3 lbs. per 1000 sq. ft.
5. Spreader setting would be 14.
