Setting Seeding Rate
Calibrating the seeding rate requires four steps:
• set correct drive type
• setting seed-rate handle
• positioning seed-cup doors
• checking seeding rate
Refer to the seed-rate charts starting on page 6.
These charts list proper sprocket sizes and seed-
rate handle settings for various seeds and
seeding rates.
The seed-rate charts are based on cleaned, un-
treated seed of average size and test weight. The
charts are based on 395/55B 16.5 12 Ply tires.
Many factors will affect seeding rates including
foreign material, seed treatment, seed size, field
conditions, tire pressure, and test weight. You like-
ly will need to make minor adjustments. Set and
check the seeding rate using procedures below,
then readjust rate as necessary.
Changing Drive Sprockets
For correct drive type, refer to seed-rate charts
starting on page 34. The charts list drive types as
1, 2, 3, or 4. Refer to the following table for the cor-
rect size sprocket for each drive type.
Refer to Figure 1
To change drive types, remove the chain guard (1)
by removing bolts (2).
Refer to Figure 2
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
connector link retainer towards the centerline and
the clip opening (split end) faces the opposite way
of the chain travel.
