USE CAUTION IN THE
OPERATION OF THIS EQUIPMENT
Most accidents, whether they occur in industry, on the
farm, at home, or on the highway, are caused
by the failure of some individual to follow simple and
fundamental safety rules or precautions. For
this reason most accidents can be prevented by recog-
nizing the real cause and doing something about
it before the accident occurs.
Regardless of the care used in the design and con-
struction of any type of equipment, there are many
conditions that cannot be completely safeguarded
against without interfering with reasonable acces-sibility
and efficient operation.
A CAREFUL OPERATOR IS THE BEST INSURANCE
AGAINST AN ACCIDENT.
THE COMPLETE OBSERVANCE OF ONE SIMPLE
RULE WOULD PREVENT MANY THOUSAND SERI-
OUS INJURIES EACH YEAR. THAT RULE IS: STOP
MACHINE TO ADJUST, LUBRCIATE, SERVICE,
CLEAN OR MOVE.
OOPERATING PRECAUTIONS
Look for this symbol to point out important
safety precautions. It means ATTENTION!
BECOME ALERT! YOUR SAFETY IS
INVOLVED.

DESCRIPTION
The Model FFD-3000VS Scattergrain is a high perfor-
mance, variable speed grain spreader, designed to pro-
vide optimum spreading for a wide range of different
type grains and bin size applications.
The Scattergrain has a grain capacity of up to 3,000
bushels per hour, depending upon the type of grain and
the moisture content.
The unit has a totally enclosed 3/4 horsepower DC
motor which is mounted directly onto an enclosed, 11 to
1 ratio gearbox assembly. The gearbox is permanently
lubricated and sealed. The main output shaft of the unit
is supported with sealed tapered roller type bearings to
assure long life and trouble-free operation.
The speed of the Scattergrain is variable between 0 to
100% and is controlled by an electronic SCR (silicon
controlled rectifier) control within the control box assem-
bly.
The unit is equipped with a patented two-way, variable
pitch grain thrower blade. With this arrangement, the
blade may be tilted, as required, to suit the roof angle,
and in addition, may be rotated within the U-bolt slots at
the "T" drive, to provide limited tilt in the second plane.
This compound angle allows the thrower blade to have
a variable bite on the grain. The adjustable center open-
ings provide for controlled center filling. The blade
extension is adjustable to allow the grain throw to be
varied.
The standard hangers supplied with the unit will adjust
to roof openings of 21 to 30 inches. For larger openings
up to 40 inches, order the optional FFD-120X extension
bracket kit.
For roof openings of 40" to 60", order optional Model
4060 bin adapter.
An optional A17-123 Flow Diverter Kit is available for
use with the Scattergrain unit. The kit is helpful in pro-
viding improved grain leveling for low capacity systems
and for special operating conditions where it is difficult
to properly center the grain flow into the unit.

INSTALLATION AND CONNECTION
1. Mount the control box at an accessible location onto
the outside of the bin or some other surface.
2. Refer to OPERATION heading and pre-adjust the
blade assembly for the bin size application.
3. Adjust the hanger extensions to fit the roof opening
and install the Scattergrain unit. Holes are provided in
the ends of the hangers to bolt unit to the hatch collar.
After unit is in place, check to make sure it is level. If
required, add spacer washers to level the unit. Then bolt
hanger brackets to the collar to prevent them from mov-
ing or becoming unhooked.
4. Rotate blade by hand to make sure it is not
obstructed.
5. Determine the length of electrical conduit and wires
required to connect motor to control box.
NOTE: Wire sizes should be 14 gauge MINIMUM.
Consult an electrician for wire size on long runs.
6. Connect the four electrical wires between the num-
bered motor leads and the numbered control box termi-
nals as listed. See Fig. 3 and wiring diagrams.

1. Blade Adjustment Information
SMALL BINS - 24' DIAMETER OR LESS - The blade
extension should be removed for small diameter bins.
For these bins, INCREASE THE TILT, as required, so
most of the grain clears the roof angle and adjust blade
for MINIMUM BITE on the grain. To obtain minimum
bite, loosen U-bolts and rotate blade fully counterclock-
wise (as viewed from above) within the slots at the "T"
drive. Fully tighten U-bolts.
Adjust the two damper discs so the center openings
within the blade are almost fully open, to provide
increased filling at center of bin.
INTERMEDITATE BINS - 36' DIAMETER - For bin diam-
eters of 36' and over, it is advisable to have the blade
extension installed and positioned so that it is fully
RETRACTED. With the extension re-tracted, it will allow
additional grain to spill over and provide increased filling
at intermediate diameters.
For these size bins, the blade should normally be set for
the greatest possible throw. This is achieved by
DECREASING the tilt of the blade so most of the grain
clears the roof angle, and adjusting the blade to provide
MAXIMUM BITE on the grain. To increase the bite,
loosen the U-bolts and rotate the blade to its fully clock-
wise position within the slots at the "T" drive, as viewed
when looking down on the blade. Tighten U-bolts
securely.
Adjust the two damper discs so the center openings
within the blade are nearly closed, to prevent over-filling
center of bin.
LARGE BINS - 50' DIAMETER OR OVER - For large
bins, adjust blade extension so it is FULLY EXTENDED
and set blade for maximum throw. See procedure as
described under previous INTERMEDIATE BINS head-
ing.
NOTE: The information within the previous headings
describe the pre-adjustments required for extremes of
bin sizes. For in-between sizes, start with intermediate
adjustments, then vary settings slightly, if required.
2. Motor Control Information
To start the Scattergrain, set power switch to ON posi-
tion and rotate the speed control knob to provide the
desired blade RPM.
3. Regardless of bin size or grain type, the grain stream
must be centered directly within the Scattergrain cone to
prevent high and low grain surface areas from one side
of the bin to the other. When starting to fill the bin,
adjust the speed control high enough so grain strikes
the bin wall slightly above grain level in bin. Increase
setting as required when filling progresses. DO NOT
OVERSPEED THE SCATTERGRAIN.
SERVICE
CAUTION: Disconnect power supply before
attempting any type of servicing.
The gear box assembly is permanently lubricated with a
special grease at the time of manufacture, and no fur-
ther lubrication is required, unless seal leakage occurs.
It is advisable to inspect seals and check bearings
annually for tightness. A bearing take-up nut is provided
externally on the output shaft to keep the tapered bear-
ings and seals snug. In the event the motor fails to start,
check unit for freedom of rotation and make certain that
power is being supplied to motor. Check for blown fuses
in control box.
IMPORTANT: If fuse replacement becomes necessary,
use only fuses of the same rating as those supplied with
