Refer to the Fertilizer Rate Chart in the Seed Rate Man-
ual to find the correct Range sprocket size for your drill’s
row spacing and target (or adjusted) application rate.
Setting High Range
Refer to Figure 51 (gray arrow shows chain direction)
High Range uses the smaller 16T sprocket
.
1. Loosen the idler sprocket and remove chain from
driving and range sprockets.
2. Open chain at removable link. Remove and save the
16-pitch section of the chain.
3. Loosen the set screws on the driving sprocket ,
and slide it on the shaft until it is in alignment with the
small 16T High Range sprocket
.
Refer to Figure 52

Re-assemble and re-mount the chain. Make sure the
open ends of all chain clips face away from the direc-
tion of chain travel (shown by the gray arrow).
5. Re-engage the idler sprocket , allowing 1 ⁄
4

(6.4mm) slack in the top chain span. Tighten set
screws
on driving sprocket .
6. If this is the final Range setting, after calibration,
repeat step 1 through step 5 for the right drill section.
