Magna Spread
The Magna Spread option for BBI fertilizer/lime spreaders allows for a wider spread swath at a
consistent rate. The option includes either four adjustable 9” or 7-1/2” fins per spinner dish in
lieu of the standard six nonadjustable 6” inch fins per spinner. The Magna Spread option also
includes a material flow divider specifically designed for the longer fins. These two elements
along with the appropriate spinner speed can produce an effective spread swath of 80’ or wider,
depending on the material density and particle size.
Because of these key components differing from standard BBI spreaders, options for adjusting
the spread pattern will vary. For proper settings, use the charts provided with your unit as a
starting point.
Spinners
The longer spinner fins can be adjusted to three different positions: straight, forward, and
backward. The position of the fins affects the manner in which the material is broadcast.
Moving the fins forward causes more material to be cast to the outside of the spread pattern (to
the sides of the truck.) Alternately, placing the fins in the back position results in more material
being thrown to the middle of the spread pattern (directly behind the truck.) For reference see
diagram below.
Spinner fin position is directly related to the material flow divider setting. As the fins are
adjusted, the flow divider setting may also need to be moved in order to produce the proper
spread pattern. For initial calibration, adjust flow divider and test results before moving spinner
fins. Refer to the “Fertilizer Calibration” section in this manual for help testing the spread
pattern.
This view shows Magna Spread spinners with the 7-1/2” fins in the “straight” position.
