Setting Main Box Seed Rate
Accurately obtaining the desired seed population
requires four steps:
1. Setting Drive Type sprockets (from chart)
2. Setting initial Seed Rate Handle (from chart)
3. Positioning Seed Cup Door (by seed type)
4. Calibration: checking actual seeding rate
Seed rate charts are found in a separate Seed Rate
Manual 195-325B (which is normally stored in a
weatherproof holder on the drill, for field reference). The
charts list proper sprocket pairings and seed-rate-handle
settings for various seeds and seeding rates.

which depicts the seed cup door handle in position

At each main seed box seed tube, adjust the seed cup
door handle

ing. If set to this position with seed loaded, it may be
difficult to reset it to a normal operating position.
