SPREADER CALIBRATION, ADJUSTMENT, AND OPERATION (continued)
spread the product. Moving the rate lever to the left will increase the time required to
spread the product.
j. If the rate lever required adjustment, add enough additional material for 1000 ft
2
of
coverage to the hopper. Measure and record the time required to spread the product.
k. If necessary, adjust the rate lever setting and repeat the spread time test until the time to
spread product for 1000 ft
2
(93 m
2
) meets the 143-foot (44 meter) travel time. Recheck
the center hole setting with the gage.
l. Using the calibration gage, check and record the center hole and third-hole settings for
future reference. Record the rate lever setting for future reference. The calibration
gauge and rate lever settings will not match.
m. To calibrate the spreader for LOW gear, set the rate lever at a lower number and spread
enough material to cover 1000 ft
2
(93 m
2
). Test and adjust the rate lever setting until the
spreader is applying the correct amount of fertilizer per thousand square feet. Recheck
the center hole setting with the gage. Record this setting for resetting the spreader.
n. Using the calibration gauge, check and record the center hole and third-hole settings for
future reference, and record the rate lever setting for future reference.
5. If the Spreader Sprayer is to be used for spreading, set the rate lever for the material to be
spread to the previously calibrated setting for the gear you intend to use. Check the
distribution pattern.
6.
Place 11 calibration pans in a line on two-foot centers on a paved area such as a
parking lot (refer to Figure 8).
NOTE: Checking and adjusting the distribution pattern
requires multiple passes over the calibration pans. This process is done on a paved area to
avoid burning the vegetation by over-fertilizing, and to allow the product to be collected and
reused.
a. With the material to be spread loaded in the spreader, make at least three passes
from the same direction over the pans in a path perpendicular to the line of pans while
spreading material.
