OPERATION
Proper pitch of spreading pans is the key to
spreading grain evenly in bin. Pitch may easily
be adjusted from top of spreader by rotating pre-
spread disc. See Fig. 7.
NOTE: Spredway adjustment wrenches, Kit
G01671,
are
available
from
Sukup
Manufacturing Co.
Maximum capacity for Standard Spredway is
3,000 bushels per hour and for High Capacity is
5,000 bph and for Super High capacity is 7,000
bph.
TO ADJUST SPREADING PATTERN:
Loosen locking handle and rotate pre-spread
disc to change pitch of spreading pans. Begin
with spreading pans in level position. Rotate pre-
spread disc clockwise to tilt pans downward.
NOTE: Change in pitch may not be noticeable
unless weight is applied to pans. Falling grain
will keep pans in correct position during
operation. Lock handle against disc.
IMPORTANT: Optimum pitch of spreading pans
depends on diameter of bin and amount of grain
flowing through spreader. Adjust so bulk of grain
hits bin wall about one ring down from eave. To
obtain best results, pitch of spreading pans may
require adjustment after initial operation.
Center flow holes (see Fig. 2) control amount of
grain that falls in center of bin. If grain is too high
in center, rotate cover to make opening smaller.
If grain is too low in center, rotate cover to make
opening larger.
Pre-spread ring is designed to allow for multiple
capacity rates. Knockouts on ring can be easily
removed to increase rates. Proper settings are
essential for peak performance. See Fig. 7 and
use table below as a guide. Ring sizes and flow
rates generally correspond to fill auger/spout
diameters.
RING SIZE RATE OF FLOW
6"
1,500 bu/hr
8"
2,600 bu/hr
10"
4,000 bu/hr
IMPORTANT: Grain flow must be centered over
pre-spread disc for even spreading.
IMPORTANT: When looking from top down,
make sure spreader is turning counterclockwise.
WARNING: Disconnect power before adjusting Spredway after installation. Contact with
rotating pans could cause death or serious injury.
