GENERAL RECOMMENDATIONS
• The chart in
figure 32.2
only represents general guidelines for certain material flow rates.
Many factors affect how a material will spread including, but not limited too, moisture content,
ambient temperature, humidity, weather conditions, brand of medium, and many more.
• For the most accurate distribution of material, always calculate the flow rates of the material
being spread.

CALCULATING MATERIAL FLOW
Calculating Material Flow
• Fill the Hopper with a known weight of the
desired material. (ex. 20 lbs of seed)
•
There is a graduated scale on the
Hopper. The units of measurement are
Gallons and Liters. For conversion of
Gallons to other units of volume
measurement use the Conversion Chart
FIGURE 32.1
.
• Place a tarp under the spreader base to catch
the dropped material for re-use.
• Open the control gate to any desired number
and time (seconds) how long it takes for all
the material to leave the hopper. This will
give you how many pounds/second at the
setting indicated on the handle decal.
• Next it is recommended to refill the same
amount of material into the Spreader. Find an
area to spread this material where you can

see the spread width. Pull the
unit at the desired speed
(recommended 3-5 MPH) to
achieve the spread width that is
desired. The faster the unit is
pulled the wider the material will
be spread. The slower the unit is
pulled, the narrower the material
will spread.
• Once you have determined your
desired pulling speed, material
spread width, and material flow
rate you can calculate the pounds
per acre for accurate coverage.
Use the work sheet and notes on
pages 30-32
to log and record
flow rates for future use.
