Main Box Seed Rate
For hydraulic drive, see page 68. With ground drive, main
seed box planting rate is controlled by:
• Range sprockets
• Transmission sprockets
• 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 manual for the page with:
- your meter type,
- your meter wheel or finger count, and;
- your approximate desired population.
The charts are provided in a separate manual (part
number 118-245B), normally stored in a
weatherproof holder on the drill.
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
conditions result in off-nominal tire slippage, some
Transmission rate adjustment may be required.
Volumetric rates usually require Transmission
adjustment 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.
