Setting Material Rates
Details of seed and fertilizer rate setting are found in the
Seed Rate Manual, and rely on data from that manual,
normally located in the manual pak enclosure at the rear
of the left wing. Rate setting controls are different for each box, but inde-
pendent for each box. All chart rates, for all boxes, are
approximate. Great Plains strongly recommends calibra-
tion of each box to the material to be applied.
Setting Main Box Seed Rate
Accurately obtaining the desired seed population
requires four steps:
1. Setting Drive Type sprockets (from chart)
2. Setting initial Seed Rate Handle (from chart)
3. Positioning Seed Cup Door (by seed type)
4. Calibration: checking actual seeding rate
Seed rate charts are provided in the separate Seed Rate
Manual (which is normally stored in a weatherproof
holder on the drill, for field reference). The charts list
proper sprocket pairings and seed-rate-handle settings
for various seeds and seeding rates.
Setting Fertilizer Rate
The 3S-3000HDF 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 in three steps:
1. Setting the Range sprocket per the Seed Rate Man-
ual
2. Setting the Driver/Driven sprockets
3. Calibrating
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.
Small Seeds rate is adjusted in two steps:
1. Setting rate handles per the Seed Rate Manual
2. Calibrating
