Regulation Bar and Adjusting Nut
Figure 8-2
Adjust regulation adjusting nut on the regulation bar to the correct setting value.
Regulation Bar

Regulation adjusting nut
Set this end of adjusting nut flush
with regulation bar set value
b. Find lbs/min in the “English Spreader Chart” on
page 41 under material being distributed that is
equal to or closest to the calculated lbs/min.
c.
Refer to Figure 8-2:
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
(English System)
The pendulum spreader can be accurately calibrated
without making a field test. With this method, knowledge
of the effective spread width, 5 gallon bucket, weigh
scales and clock are need to calibrate the spreader.
1. Complete
“Regulation Bar (English System)”
adjustment instructions on page 38 before continuing
with step 2.
2. Remove spout by removing the 2 bolts and nuts
connecting the spout to the spreader.
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 pounds of material in the bucket to
lbs/min in the
“English Spreader Chart”
on page 41
or to the “Slide Ruler Calibration (English System)”
on page 40. Pounds of material in the bucket and lbs/
min should be the same.
8.
Refer to Figure 8-2:
If weight of material in the bucket
does not equal lbs/min readjust regulation adjusting
nut to increase or decrease discharge rate and repeat
steps 3 to 7 until required discharged rate in lbs/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
(English System)
The spreader can be calibrated in the field in one acre
plots with the assistance of the
“English Spreader
Chart” on page 41.
1. Complete
“Regulation Bar (English System)”
instructions on page 38 before continuing with step 2
below.
2. Mark out one acre the tractor will travel over.
Remember to use effective spread width when
calculating the acre.
Example:
a. Say overall spread width is 80 feet. Divide 80 by 2
for an effective spread width of 40.
b. One acre equals 43,560 sq ft.
43,560 divided by 40 = 1,089 ft of travel distance
c. The tractor will need to travel 1,089 ft to cover one
acre.
3. Fill hopper with precise amount of material in pounds
to cover one acre.
4. Make a test run dispersing product while traveling
over the pre-marked acre at the required ground
speed with engine rpm speed set at 540 power take-
off speed.
5. Refer to Figure 8-2: 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 to 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.
