3. Move the machine far enough away from the
test area (where the collection pans are located)
to ensure that the machine travels at the desired
spreading speed before reaching the site.
4. Determine the application rate and the related
drop-rate cam setting; refer to
(page 31).
5. Rotate the drop rate cam
setting you determined in step 4.

6. Ensure that the hopper-door control is in the
close position, and fill the hopper approximately
half-full with the desired material; refer to
Controls (page 26).

Determining the Distribution Pattern
1. Set the diffuser control to the middle of its travel
and lock it; refer to
(page 27).
2. Adjust the impeller speed control to set the
broadcast pattern width; refer to
Impeller-Speed Control (page
3. Drive the machine toward the test site at the
appropriate speed.
4. As you approach the center pan, pull the wide
distribution granular gate control to the open
position, and drive over the center pan.
5. Close the gate control, move motion-control
lever to the N
engine, wait for all moving parts to stop, remove
key, and engage parking brake.
6. Label each graduated measuring cylinder to
correspond with the distribution pans (such as
L2, L1, Center, R1, R2); refer to
Figure 23.
7. One at a time, take a collection pan and dump
the contents into the corresponding graduated
cylinder. Record the amount of granular material
collected and return the pan to its location.
Repeat this until all pan contents have been
emptied.
Note:
Repeat broadcasting over the test site
several times, moving in the same direction
each time, until enough material is dispensed to
the collection pan to half fill a graduated cylinder.
8. 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.
9. To adjust the spreader pattern, refer to the
Adjusting the Spreader Pattern (page
10. Fill the hopper half-full of the desired material
and repeat steps
a uniform pattern.
Determining the Effective Spreading Width
Use the effective width to determine the uniform
distribution of the granular material.
Note:
The spreading width range is 1 to 8 m (3 to
25 ft).
1. After the spreader pattern is correctly adjusted,
evaluate the amount of material in the center
graduated measuring cylinder.
2. Locate the 2 graduated cylinder, one each
side of center, that contains 1/2 the measured
