5.
Choose the speed (kph) column that is closest to the
planned field speed.
Example: field speed planned is 9.6 kph (use 10.5)
6.
Find the fertilizer rate closest to your corrected or
target rate.
Example: density corrected rate is 137.5 kg/ha (use
136)
7.
In the Transmission columns to the left, find the
DRIVING and DRIVEN sprocket tooth counts
required for the chosen chart rate.
Refer to Figure 15
8.
Inspect the current DRIVING
and DRIVEN
transmission sprockets. It is likely that one or both
need to be changed. If no sprockets need to be
changed, continue at “Dry Fertilizer Rate Check”
on page 35.

Loosen the bolt at the idler plate
. Rotate the idler
plate to relax chain tension. Lift the chain of the
DRIVING and/or DRIVEN sprockets that need to be
exchanged.
10. Remove the pins from any sprocket that needs to be
changed, and from the storage tree
.
11. Exchange sprockets between shafts and tree as
needed to match the chart values.
12. Re-engage the idler plate for 1.8 mm chain slack
(see Operator manual for information on chain slack
and chain orientation). Tighten the bolt of the idler
plate.
