Liquid Fertilizer Attachment
!
WARNING!
Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions supplied
by the chemical manufacturer.
On machines equipped with optional squeeze pumps, the
rate of liquid fertilizer application is determined by the
combination of sprockets on the squeeze-pump shafts.
When changing sprocket combinations, make sure
sprockets are aligned, sprocket retaining collars are tight
and chain tension is sufficiently restored.
The chart on this page provides approximate application
rates. Actual rates will vary with temperature and the par-
ticular fertilizer being used.
NOTE: If placed too close to the seed, certain analysis of
fertilizer may cause germination or seedling damage, es-
pecially if used in amounts in excess of fertilizer manufac-
turer’s recommendations. Check with your fertilizer dealer
or manufacturer for the correct amount and placement.
Dry Fertilizer Attachment
Use the following instructions to check the exact number
of pounds your fertilizer attachment will actually deliver on
30-inch row spacing.
1.
Remove a hose from one of the fertilizer hoppers and
attach a container under the opening.
2.
Engage the fertilizer attachment and drive forward for
174 feet.
3.
Weigh the amount of fertilizer caught in the container
and multiply that amount by 100. The result will be the
pounds of fertilizer delivered per acre when planting
on 30-inch rows.
To assure proper application check the gauge tires and
contact drive tire for proper inflation. See Tire Inflation
Chart in “Appendix,” page 62.

IMPORTANT: Fertilizer application rates can vary
from the weights in the charts. Make field checks to
assure you are applying fertilizer at the desired rate.
IMPORTANT: Before applying fertilizer make sure
that augers are rotating correctly and are positioned
for your desired rate setting. See Figure 3-6 and Fig-
ure 3-7.
