4.10 CHECKING FEED RATE
1. Measure a distance of 415’ on a drill with 7” spacing and mark. Remove one hose from seed hopper on
each drill. Attach a container (cloth or plastic bag) to hopper to collect seed.
2. Operate drill at intended planting speed through entire length of test track.
3. Weigh the sample in ounces (less weight of sample container). Use the following formula to determine
lbs./acre for your particular shank spacing.
7” Spacing - oz. x 11.25 = lbs./acre
EXAMPLE
Sample and container weighs 9.9 ounces
Container weighs - 1.5 ounces
Weight of sample only 8.4 ounces
4. Use formula No. 1 to figure pounds per acre. 8.4 ounces x 11.25 = 94.5 pounds per acre.
5. To calibrate a seed not shown on the chart or a mix of different seeds, compare to a similar charted seed to
obtain a trial setting. Recalibrate as necessary.
6. The same method may be used to determine fertilizer rates.
The addition of the single agitator to the standard drill box will prevent these seeds from bridging above the feed
wheels. The single agitator may be added to all 147C Drills.
