Dry Fertilizer Adjustment
There are two adjustment for dry fertilizer:
• Fertilizer Rate (below), and;
• Applicator tube height (page 46).
Dry Fertilizer Rate
This page is a summary. See Seed and Fertilizer Rate
manual (401-754B) for complete details.
Refer to Figure 31
Dry fertilizer rate is set by a pair of Transmission
sprockets at the left side of the planter. Sprocket parings
for desired application rates and field speeds are given in
charts in the Seed and Fertilizer Rate manual.
Note: Dry fertilizer rate is independent of seed rate.
Changes in seed rate do not affect fertilizer rate.
Application Rate Risk:
Make field checks to assure you are applying fertilizer at the
desired rate. Fertilizer application rates vary with speed,
material density, material granularity and atmospheric
conditions. The charts provide only approximate rates for a
specific density. See “Dry Fertilizer Rate Check” in the Seed
and Fertilizer Rate manual.
Frame-Mounted Accessory Adjust-
ments
To get full performance from your planter, you need a
good understanding of row cleaner, coulter, fertilizer,
opener, meter, seed firmer, and press wheel operation.
Coulter Adjustments (Option)
Refer to Figure 32 and Figure 33
Frame-mounted coulters are installed on the front face of
the front tool bar. They may have straight shanks
(as shown), or offset shanks.
Coulters normally operate resting on their down-stops,
rising up against the spring as difficult obstacles are
encountered. If the coulter springs are routinely in
compression, coulters are set too deep for the field
conditions.
There are 4 adjustment for coulters:
1. coulter height / blade depth (below)
2. blade angle (page 45)
3. row alignment (page 45)
4. blade style (page 45)
Note: Do not adjust the coulter spring length .
It is factory preset to 25.0-to-25.4 cm.
