Main and Dual Box Seed Rate
Accurately obtaining the desired seed population
requires four steps:
1. Setting Drive Type gearbox (from chart)
2. Setting initial Seed Rate Handle (from chart)
3. Positioning Seed Cup Door (by seed type)
4. Calibration: checking predicted seeding rate
Seed rate charts begin on page 8. The charts list proper
Drive Type and seed rate handle settings for various
seeds and seeding rates.
The seed rate charts are based on cleaned, untreated
seed of average size and test weight. The charts are
based on factory-supplied 5.70-8 8-Ply tires inflated to
factory specification. Many factors affect seeding rates
including foreign material, seed treatment, seed size,
seed weight, field conditions, tire pressure and test
weight.
Use the charts only as a starting point. Minor
adjustments are commonly required. Set and check the
seeding rate using the procedures beginning on page 6,
then readjust the rate as necessary.
Setting Drive Type
Refer to Figure 3
The charts list Drive Types as 1, 2, 3 or 4. Drive Type is
determined by the handle
on the gearbox cover, at left
front of drill.
Move the handle until the Drive Type number appears in
the handle window
.
For correct Drive Type, refer to the charts in the Seed
Rate manual. Each Drive Type corresponds to a specific
gear ratio.
Note: The gear box is shared between Main Seed Box
and the optional Dual Seed and Native Grass
boxes. It is possible to plant from both boxes at the
same time only if their settings use the same Drive
Type.
