Dry Fertilizer Adjustment
There are two adjustment for dry fertilizer:
•
Fertilizer Rate (below), and;
•
Applicator tube height (page 44).
Dry Fertilizer Rate
The balance of this page is a summary. See
(401-754B) for complete details.
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
.
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
.
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 43)
3. row alignment (page 43)
4. blade style (page 43)
Do not adjust the coulter spring length . It is factory
preset to 25.0-to-25.4 cm.
