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.
