Meter Rate Adjustment
Check Flute Shaft Configuration
Refer to Figure 83
(which depicts a single flute “star” with its halves, a single star
mated, two stars staggered, small seeds, and a filler)
Know your “stars” (dosing roller) setup. If your air cart
has never been changed from factory standard, you have
meter flute shafts with two deep-flute “stars”
(4 halves)
per outlet. How many “stars” you have determines which
rate to use.
Refer to Figure 84 (depicting an inspection from below meter)
If the configuration is not known, inspect the flute shaft
from the hopper lid (if hopper empty), or from below the
meter, with the calibration door fully open. It is not
necessary to remove the shaft. Inspect the flutes
, and
filler rings
at active outlets.
On a standard “2 star” shaft, each seed drop outlet
contains two flute sets (4 halves), each pair staggered
slightly from the next. Unused outlets are fully blocked by
filler rings
.
On an optional “3 star” shaft, each outlet contains 3 flute
sets of the deep style
.
On an optional “4 star” shaft, each outlet contains 4 flute
sets of the deep style
, with no fillers between adjacent
drops.
On an optional Small Seeds shaft, each outlet contains
one set of narrow, shallow flutes
.
To change meter flutes, see “Changing Meter Flutes”
on page 72.
