Dry Fertilizer Adjustment
There are two adjustment for dry fertilizer:
• Fertilizer Rate (below), and;
• Applicator tube height (page 45).
Dry Fertilizer Rate
The balance of this page is a summary. See Seed and
Fertilizer Rate manual (401-754B) for complete details.
Refer to Figure 34
Dry fertilizer rate is set by a pair of Transmission
sprockets at the left side of the implement. 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.
Although the dry fertilizer drive relies on the same
ground drive and main shaft as the seed metering
system, changes in seed rate do not affect those
drive components.
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 Adjustments
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 35 and Figure 36
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 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.
