• Using the Third-hole Lever, position the Third-hole Adjust-
ment Plate against the Calibration Gage and position the
Memory-Lock until it pops into the Lever and locks its posi-
tion.
•
Remove the Calibration Gage.
•
Close and open the Third-hole several times and verify the
Third-hole setting is 13. Readjust as necessary.
• Record both the Calibration Gage setting and the Memory-
Lock setting for future use. NOTE: The correct Calibration
Gage setting must be verified from time to time.
• The Memory-Lock setting is adequate for reference in the
field, but it must be adjusted to the Calibration Gage during
the Daily machine Servicing.
.
Determine the Rate Adjustment Knob setting for each product that
will be used. NOTE: The machine is designed to apply fertilizer
evenly by overlapping 50 percent of the last pass. Most fertilizer
products spread 14 foot wide. One half of 14 feet (or 7 feet) is the
effective material spread width, and used as the basis for calibra-
tion.
•
Measure AND RECORD the amount of time it takes to spread
1,000 ft
2 (93 m 2 ) of area.
• Measure a distance of 143 feet (44 meters) over turf. This
will provide a spread area of approximately 1,000 ft
2 (93
m 2 ). The effective material spread width for most products
is 7 feet; therefore, 7 x 143 = 1,001 ft 2 (93 m 2 ).
•
With the machine in neutral (and the hopper closed), run the
engine at full throttle. Check the tachometer to make sure
the engine is running at 3450 rpm. Once we know that the
engine is operating at the correct speed, we can be sure
that you’ll be traveling at the right speed and that the appli-
cation rate is correct, as well.
• With the machine traveling in HIGH at full throttle, use a
stopwatch or wristwatch to measure AND RECORD the time
required to travel the 143-foot (44 meter) turf course. The
normal time is approximately 20 seconds ± 1 seconds.
•
With the machine operating in LOW at full throttle, RECORD
THE TIME required to cover the 143-foot (44 meter) turf
course. The normal time is approximately 28 seconds ± 1
second.
•
Measure and adjust the output of the spreader to deliver 3
pounds (1.36 Kg.) per 1,000 ft
2 (93 m 2 ).
•
Place a ground cloth on a paved area.
•
Place enough product in the Hopper to conduct several
delivery rate checks.
•
Drape a drop cloth over the Hopper to contain and deposit
the product spread onto the Ground cloth.
•
With the machine in Neutral, accelerate the engine to full
speed and open the Hopper for the actual time you re-
corded for the High Gear time test above (for our example
we will use 20 seconds).
• Move machine off Ground cloth and weigh the product col-
lected.
•
If the product collected weighs less that 3 pounds (1.36
Kg.), reposition the Rate Adjustment Knob to a higher set-
ting on the Rate Scale to increase the opening in the Hop-
per. Repeat the collection test and readjust as required.
• Once the proper rate has been established RECORD the
Rate Adjustment Knob and Calibration Gage settings for
future use.
• Repeat the procedure for the Low Gear time (for our exam-
ple we will use 28 seconds).
•
Check and adjust the distribution pattern.
• Place 11 calibration pans in a line on two-foot centers on a
paved area such as a parking lot. 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.
• With the material to be spread loaded in the spreader, make
Spreader Operation 23
at least three passes from the same direction over the pans
in a path perpendicular to the line of pans while spreading
material.
• Pour the contents of the first pan on your far left into the
graduated cylinder or clear tube. Measure and record the
material deposited. Dump the collected pellets back into the
bag or hopper. Repeat this measurement for each pan, one
by one, until all eleven pans are emptied and recorded.
•
The distribution pattern should be balanced as in Figure
13A with a higher amount of product, collected in the center
pan and tapering off equally to both sides. NOTE: The distri-
bution pattern shown in FIGURE 13A represents the ideal
pattern, which will not be reproducible in the field. The
numbers are used for reference only.
•
To balance the distribution pattern for the right side, move
the lever as necessary to increase or decrease the opening
in the adjustment hole. Reset the memory lock.
•
Repeat the passes over the pans and measure the material
deposited in the pans. Readjust the openings as necessary
until the distribution pattern meets the requirements.
•
Record each opening setting for future recalibration.
