Many factors will affect seeding rates including for-
eign material, seed treatment, seed size, field
conditions, tire pressure and test weight. You likely
will need to make minor adjustments. Set and check
the seeding rate using procedures below, then re-
adjust rate as necessary.
Changing Drive Sprockets
For correct drive type, refer to seed-rate charts
starting on page 34. The charts lists drive types as
1, 2, 3 or 4. Refer to the following table for correct-
sized sprocket for each drive type.
Refer to Figure 31
To change drive types, remove the chain guard (1)
by removing bolts (2).
Refer to Figure 32
Loosen idler (1) and remove drive chain. Remove
lynch pin from shaft (2) and re-arrange sprockets on
shaft.
NOTE: Be sure chain is installed with the chain con-
nector link retainer towards the centerline and the
clip opening (split end) faces the opposite way of
the chain travel.
Setting Seed-Rate Gauge
Refer to Figure 33
Important! Read gauge from left-hand side of
plate.
Position seed-rate gauge to setting indicated on
seed-rate charts.
Use the hand crank to rotate the screw located on
the right-hand side of the drill. Rotate the screw one
way or the other until the gauge is at the desired
setting.
