Dry Fertilizer Operation (Option)
Great Plains recommends checking with your local
agronomist prior to setting the rate, as soil conditions
vary.
On ground drive planters, the fertilizer meters are driven
from the same ground drive that powers the seed
metering system. On hydraulic drive planters, the
fertilizer meters are driven by a dedicated ground drive.
When the planter is lowered and in motion, the fertilizer
meters operate, and fertilizer is applied based on the rate
controlled by the selection of fertilizer transmission
sprockets. Sprocket selection is the same for shared or
dedicated fertilizer ground drive.
See the Seed and Fertilizer Rate manual (401-923B)
for rate charts and detailed information on rate setting.
The outlets of the fertilizer meters are normally
connected to fertilizer drop tubes at the dry fertilizer
coulters. See page 61 for adjustment of drop tube height
and angle.
Refer to Figure 46
If fertilizer will not be applied, disengage the drive
coupler at the left end of the left fertilizer hopper:
1.
Remove the pin
from the coupler
.
2.
Slide the coupler left, completely off the driven
shaft
, and clear of both the shaft gap and the pin
hole in the driving shaft
.
3.
Re-insert the pin in the driving shaft (not through the
coupler). Secure pin to shaft with wire bail.
To restore fertilizer drive operation, first rotate the driven
shaft to align its pin hole with the hole in the coupler.
Slide the coupler right. Re-insert pin through both
coupler and driven shaft. Secure pin with wire bail.
Material Loss / Machine Damage Risks:
Pin coupler clear of shaft gap. It may be possible to insert the
pin through both the coupler
and the driving shaft
.
Do not do this. This may leave the coupler and driven shaft in
contact. Field motion could cause the meters to operate. The
coupler and driven shaft
could also be damaged.
