Setting Main Box Seed Rate
Accurately obtaining the desired seed population from
the main seed boxes requires four steps:
1.
Setting Drive Type sprockets
(page 3, based on chart)
2.
Setting initial Seed Rate Handles
(page 4, initially based on chart)
3.
Positioning Seed Cup Doors
(page 4, based on seed type)
4.
Calibration: checking actual seeding rate
(page 5)
Seed rate charts, and rate setting/calibrating information,
is included in both the Operator Manual, and this
separate Seed Rate Manual. The Seed Rate manual is
normally stored in a weatherproof holder on the drill, for
field reference. The charts list proper sprocket pairings
and rate-handle settings for various materials and rates.
The seed-rate charts are based on cleaned, untreated
seed of average size and test weight. The charts are
based on factory-supplied tires, inflated to factory
specification. Predicted rates may vary slightly with rib
implement tires, optional on some models.
Many factors will affect seeding rates including foreign
material, seed treatment, seed size, seed weight, field
conditions, tire condition, tire pressure and test weight.
Minor adjustments are commonly required. Set and
check the seeding rate using the procedures following,
then re-adjust the rate as necessary.
