SEED HAWK ® 2015 LOUP III & VIPER PRO™ HYDRAULIC DRIVE CALIBRATION GUIDE 34
Seed size, seed type, seed coatings, seeding speed and other variables all have an effect on the actual product
application rate The Rate Check Calculation compares actual weight of product seeded to actual acres applied.
For best results weighing product is recommended.
Rate Check - Rate Check Procedure
5. Divide the Total Weight of Product Used by the To-
tal Amount of Acres Seeded to get the
Actual Rate
6. Divide the Actual Rate by the Target Rate to get
the
Correction Factor
7. Multiply the Current Cal. Weight by the
Correction Factor to get the
New Cal Weight
8. Continue seeding with the New Cal Weight
1. Fill tank with a known amount of product
2. Enter in a calibration number from the
Calibration Numbers chart (pg. 1). If product is
not listed perform a static calibration.
3. Seed a test area of predetermined acreage and
record the amount of acres applied
(more acres
seeded means a larger sample which will make the
rate check more accurate)
4. Weigh product remaining in tank
(Initial Weight - Final Weight =
Total Weight of Product Used)
