Setting Fertilizer Rate
The 2S-2600F or 2S-2600HDF fertilizer meters are
driven from the clutch shaft through a series of
sprockets. This system is independent of the seed meter
drive, and is unaffected by Drive Type. Fertilizer rate is
adjusted by changing 1 to 3 sprockets on each drill
section (2 sets total).
Fertilizer application rates vary with fertilizer type,
density and particle size. Relative humidity and field
conditions can also affect application rates. The chart in
the Seed Rate Manual 195-325B is based on fertilizer
with average particle size and a density of 65 pounds per
cubic foot. Initially set rate according to charts, then
calibrate the drill to your material as described on this
page.
Perform initial setup and calibration for the left drill box.
Once final are determined, set the right box to match.
Accurately obtaining the desired application rate requires
four steps:
1. Adjusting target rate for large differences between
material and chart density.
2. Setting Range sprocket (from chart)
3. Setting initial Driver / Driven sprockets (from chart)
4. Calibration: checking actual application rate
Small Seeds Rate
Seeding rate from the optional Small Seeds Attachment
is controlled entirely by seed rate handles on each small
seeds box. No sprocket changes are required, and small
seeds rate is unaffected by settings for main seed box.
Refer to Figure 47
To set Small Seeds rate, loosen the wing nut
at each
handle, and adjust the lever position. Tighten nut.
Set the initial rate based on the chart in the Seed Rate
Manual 195-325B.
