3. Measure of an acre. See chart for correct distance for row width being planted. For example, if planting 30"
rows of an acre would be 17' 5".
NOTE: Seeds may bounce or roll when planting with closing wheels raised and planting depth set shallow
affecting seed spacing accuracy.
4. Count seeds in measured distance.
5. Multiply number of seeds placed in of an acre by 1000. This gives total population.
Seed count can be affected by drive wheel and seed meter drive ratio, tire pressure, and/or seed meter malfunction.
1. If seed check shows average distance between seeds in inches is significantly different than seed rate chart
indicates, first check drive ratio between drive wheel and seed meter. Check drive wheel air pressure, check for
incorrect sprocket(s) in driveline and check drive and driven sprockets on transmission(s) for proper selection.
2. Check for seed meter malfunction. For example, if spacing between kernels of corn at the transmission setting
being used is 8" and a gap of 16" is observed, a finger has lost its seed and not functioned properly. If two seeds
are found within a short distance of each other, the finger has metered two seeds instead of one.
3. See “Finger Pickup Seed Meter Troubleshooting” and/or “Brush-Type Seed Meter Troubleshooting” in the
Troubleshooting Section of this manual.
Acre Seed Population Count Row Width/Distance
Row Width 15" 18" 19" 30" 36" 38"
Distance 34'10" 29'0" 27'8" 17'5" 14'6" 13'10"
EXAMPLE: 30" row spacing 17' 5" equals acre.
26 seeds counted x 1000 = 26,000 seeds per acre
