b. Find kg/min. in the “Metric Spreader Chart”
under material being distributed equal to or
closest to the calculated kg/min.
c.
Refer to Figure 8-5:
Adjust regulation adjusting
nut to this new setting.
9. There are several different Calibration methods to
verify the regulation bar is set correctly. They are
Stationary Calibration, Field Calibration, and Slide
Ruler Calibration. The Slide Ruler Calibration is a
tool to assist Stationary and Field Calibrations. See
instructions for Stationary Calibration or Field
Calibration on this page.
Stationary Calibration
(Metric System)
The pendulum spreader can be accurately calibrated
without making a field test. With this method, knowledge
of the effective spread width, 18 liter bucket, weigh scales
and clock are need to calibrate the spreader.
1. Complete
“Regulation Bar (Metric System)”
instructions on page 38 before continuing with
step 2.
2. Remove spout by removing the 2 bolts and nuts
connecting the spout to the spreading unit.
3. Position a bucket under the spreader to catch
discharged material.
4. Restart tractor, set power take-off speed at 540 rpm
and open discharge gate for only 1 minute and then
close gate.
5. Disengage power take-off, shut tractor engine off,
remove switch key and wait for power take-off to stop
rotating before dismounting from tractor.
6. Weigh material discharged into the bucket.
7.
Compare kilograms of material in the bucket to
kg/min in the
“Metric Spreader Chart”
on page 45 or
to the “Slide Ruler Calibration (Metric System)” on
page 44. Kilograms of material in the bucket and
kg/min should be the same.
8.
Refer to Figure 8-5:
If weight of material in the
bucket does not equal kg/min, readjust regulation
adjusting nut to increase or decrease discharge rate
and repeat steps 3-7 until required discharged rate in
kg/min is obtained.
•
Adjust regulation adjusting nut to a higher number
will increase discharge rate.
•
Adjust regulation adjusting nut to a lower number
will decrease discharge rate.
Field Calibration
(Metric System)
The spreader can be calibrated in the field in one acre
plots with the assistance of the
“Metric Spreader Chart”
on page 45.
1. Complete
“Regulation Bar (Metric System)”
on
page 42 before continuing with step 2 below.
2. Mark out one hectare the tractor will travel over.
Remember to use effective spread width when
calculating the hectare.
Example:
a. Say overall spread width is 24 meters. Divide 24
by 2 for an effective spread width of 12.
b. One hectare equals 10,000 square meters.
10,000 divided by 12 = 833.3 meters of travel
distance
c. The tractor will need to travel 833.3 meters to
cover one hectare.
3. Fill hopper with precise amount of material in pounds
to cover one hectare.
4. Make a test run dispersing product while traveling
over the pre-marked hectare at the required ground
speed with engine rpm speed set at 540 power take-
off speed.
5. Refer to Figure 8-5: If hopper emptied too soon or if
hopper still has material in it after covering one acre,
readjust regulation adjusting nut to increase or
decrease discharge rate and repeat steps 2-4 until
required discharged rate is obtained.
•
Adjust regulation adjusting nut to a higher number
will increase discharge rate.
•
Adjust regulation adjusting nut to a lower number
will decrease discharge rate.
