Setting Application Rates
The most accurate way to set application rates is to drive a predetermined distance and physically catch the
seeds dispensed. To do this, remove at least one drop hose and tie a plastic bag onto bottom of seed cup. Trav-
el a determined distance and then weigh the seeds in the bag. Multiply the amount collected by the number of
cups on your machine. Refer to the following example to properly calibrate your machine.
To determine area covered calculate the following:
(Disc spacing x number of discs converted to ft.) x distance traveled and then divide by the square feet in an
acre.
10 disc with a 7.25" spacing = 72.50" (6.04 ft.) x 500 ft. traveled = 3,020 sq. ft. covered.
43,560 sq. ft. in acre/3,020 = 14.42% of acre covered.
If you collect 16 oz. (1 lb.) of seed from a single seed cup on the #5 setting after driving 500 ft.
(14.42% of an acre), you are putting out 69.35 lbs. per acre.
1 lb. (amount collected) x 10 seed cups = 10 lbs. total output by machine.
Distance traveled = 500 ft. (14.42% of acre)
1 x 10 / .1442 = 69.35 lbs. per acre
NOTE: The tables and rate charts are guidelines only! They are designed to be an aid as a starting point. You
must do your own calibration as many factors cause rates to change. Variations in seed/granular size, density,
moisture, seed treatment, and the amount of machine overlap will affect the final application rate.
Refer to pages 16 & 17 for "Rate Charts".
