Seed Rate Calibration
The provided charts were determined by laboratory tests
on various samples. To find rates for specific seed lots or
to calibrate for unlisted seeds, proceed as shown on the
seed chart.
Machine May Be Calibrated for Unlisted Seed as Follows:
1. Remove the chain between 17 Tooth and 19 Tooth
2. Raise the machine and lock in transport position.
3. Place a canvas or tarp in position to catch seed.
4. Turn the 3/4 Hex on sprocket shaft counterclockwise
(CCW).
1195 Revolutions for 4 Foot Seeder.
955 Revolutions for 5 Foot Seeder.
795 Revolutions for 6 Foot Seeder.
5. Weigh the seed for approximate planting rate.
6. Fewer turns may be used if results are adjusted by
turning 3/4 Hex on sprocket shaft counterclockwise
(CCW).
239 Revolutions for 4 Foot Seeder.
191 Revolutions for 5 Foot Seeder.
159 Revolutions for 6 Foot Seeder
and multiplying the weight by 5.
PLANTING RATES FOR SEED METER
(FRONT BOX) IN POUNDS PER ACRE:
• Rates are for the 13-Tooth Driver Sprocket.
• Rates are intended as a guide only. Variations in size
and cleanliness will affect rates. Check acreage and
pounds of seed used for best results.
