Check Flute Shaft Type
For some unusual very high rate applications and some
small seeds, Great Plains offers alternate meter flute
shafts (page 85) that change rates to 150%, 200% or
approximately 25% vs. the factory standard shaft.
Refer to Figure 66
(which depicts a single flute “star” with its halves, a single star
mated, two stars staggered, and a filler)
Know your “stars” setup. If your air drill cart has never
been changed from factory standard, you have standard
meter flute shafts with 2 “stars” (4 halves) per outlet.
How many and what type of “stars” you have determines
which rate chart to use.
Refer to Figure 67
(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
(
or ), and filler rings at active outlets.
On a standard “2 star” shaft, each seed drop outlet
contains two standard flute sets (4 halves
), each pair
staggered slightly from the next. Unused outlets are fully
blocked by filler rings
.
On a “3 star” shaft, each outlet contains 3 flute sets.
On a “4 star” shaft, each outlet contains 4 flute sets,
with no fillers between adjacent drops.
On a small seed shaft, each outlet contains one set of
shallow flutes
.
