Non-Standard Configurations
If you modify your row spacing by plugging seed meters,
this may alter the revolutions per acre or hectare.
Measure between the centerlines of the active end rows
(the Span). If the change was to simulated twin-row, treat
each pair as a single row, and measure to pair centerline.
The new swath is the measurement times the new row
count.
Check the Dimensions for your drill in the Appendix of
the drill Operator Manual. SpecSwath below is the fac-
tory specification), If the swath changed, adjust the revo-
lutions as follows:
If you are using markers, also re-check the marker exten-
sion. See page 21.
Main Box Seed Rate
Main seed box planting rate is controlled by:
• Drive Type sprocket set
• Seed Rate handle setting
• Seed Cup door setting
Before setting the rate, raise the drill and rotate the
gauge wheels. Check that seed meters, seed tubes and
drives are working properly and are free from foreign
material.
The procedure for setting the main box rate is:
1. Consult chart for your crop in the Seed Rate manual.
Note initial Drive Type and Rate Handle settings.
2. Configure Drive Type and Seed Rate handle on one
or both sides of the drill.
3. Set the Seed Cup doors per advice on page 33.
4. Calibrate the drill for your specific seed.
5. Set both gauge wheels and rate handles identically.
Note: Many factors affect seeding rates: seed treatment,
weight of seed, size of seed, surface condition of
seed, tire configuration, tire pressure and tire slip-
page. Minor adjustments may be needed to com-
pensate for these factors.
