Main 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 new tires:
5.70 x 8 tire for 3P605NT and 3P606NT drills, and
7.00-15LT tires for 605NT and 606NT drills,
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 5,
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 the 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: Drive Type affects both Main Box and optional
Native Grass seed rates.
