Main Seed Box Planting
For hydraulic drive, rate is set directly on the hydraulic
drive console. See the Hydraulic Drive section of the drill
Operator Manual (118-245M).
With ground drive, main seed box planting rate is con-
trolled by:
• Range sprockets,
• Transmission sprockets, and;
• Seed meter type, and finger count or seed wheel cell
count
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. Install the appropriate meters and wheels.
2. Enable or disable any rows, as needed.
3. Consult the Seed Rate chart for:
- your meter type,
- your meter wheel or finger count, and;
- your approximate desired population.
4. For your specific population and planting speed, note
the Range and Transmission sprocket pairs.
5. Configure the Range sprockets on each gauge
wheel assembly,
6. Configure the Transmission sprockets above each
gauge wheel assembly.
7. Check the seeding rate.
The checking procedure is different for singulated
and volumetric seeds.
Singulating chart rates are generally precise, and
need only furrow or seed monitor verification. If tires
are not at factory specification, and/or field condi-
tions result in off-nominal tire slippage, some Trans-
mission rate adjustment may be required.
Volumetric rates usually require Transmission adjust-
ment to account for the variation between your seed
and the seed used to develop the chart, in addition to
any factors of tire and field conditions.
