towards pans
2. Center pan
3. Collection pans (gap
between each)
• For smaller granule materials:
Place six additional pans, on each side, with
no gap in between each pan (Figure 29).

2. Center collection pan
3. Left collection pans (no
gap between each)
4. Reference the Spreading Charts section to
determine the appropriate rate dial setting (see
Figure 11).

5. Fill the hopper approximately half-full with the
desired material.
6. Set the impeller speed to the appropriate
broadcasting rate.
7. Pull the wide distribution granular gate control to
the open position and drive the spreader, at the
appropriate speed, over the center pan. Repeat
this several times, moving in the same direction
each time, until enough material is dispensed to fill
the center graduated measuring cylinder half full.

8. Label each graduated measuring cylinder to
correspond with the distribution pans (i.e. ...L2,
L1, Center, R1, R2....) (reference Figure 28 and
Figure 29).
9. One at a time, take a collection pan and dump
the contents into the corresponding graduated
measuring cylinder. Record the amount of
material collected and return the pan to its
location. Repeat this until all pan contents have
been emptied.
10. With the graduated measuring cylinder in the
same straight line as the pans, evaluate the volume
of material in each cylinder to determine the
quality of the distribution from the spreader.
11. To adjust the spreader pattern, refer to the
Spreader Pattern Adjustment section.
12. Repeat steps 5 through 11 until an uniform
pattern is achieved.
Determining the Effective Spreading
Width
The effective width is used to determine the uniform
distribution of the material.
Note: The spreading width range is 4 ft (1.2 m) up
g027327
to 22 ft (6.7 m).
1. After the spreader pattern is correctly adjusted,
evaluate the amount of material in the center
graduated measuring cylinder.
2. Locate the two tubes, one each side of center, that
contain 1/2 the measured amount of the material
that you observed in the center graduated cylinder.
3. Go to the two corresponding pans. Starting from
the outer edge, measure and record the distance
between left pan, through the center pan, to the
outer edge of the right pan.
