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 the squeeze pump option, the 
rate of liquid fertilizer application is determined by the 
combination of sprockets on the squeeze pump driven and 
drive shafts. When changing sprocket combinations, 
make sure sprockets are in alignment, 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
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.
Use the following instructions to check the exact number 
of pounds your fertilizer attachment will actually deliver on 
a 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 in 
30-inch rows.
To assure proper application check the gauge tires and 
contact drive tire for proper inflation, see Tire Inflation 
Chart in “Appendix” on page
55.
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.
