NOTE:
The speedometer reads actual hose speed ONLY on the base (1st) layer of
hose.
If the retrieve rate is set or checked on the second, third, or fourth layer, the
desired retrieve rate must be set to the “corrected value” for the layer being
loaded. This is easily done by referring to the chart attached to the machine next
to the speedometer. This “corrected value” is read directly from the
speedometer.
(eg.): The desired retrieve rate is 30 inches per minute. The hose is on the
second layer when the speed is set. On the SPEED CONVERSION
CHART, find 30 inches per minute in the line labeled BASE LAYER. Read
the corrected speed value on the 2ND LAYER line in the 30 inches per
minute column.
Set the speed so the speedometer reeds this corrected value (27).
The actual hose speed will be 30 inches per minute
If you are unsure of your retrieve rate for any reason, manually check the
retrieve rate by measuring the hose movement over a three (3) minute period
and average this measurement (divide by 3).
7. Shift the transmission lever to engage the drive system.
8. Fully release the brake.
9. Make a thorough visual inspection of the of the machine’s function to insure proper
operation.
EXAMPLE OF RETRIEVE RATE SELECTION
Determine the retrieve rate required to apply a 1.25” application to a field 350 feet in
width.
A 4500 model traveller is fitted with a Nelson SR-200 gun. The gun has a 1.56” ring
nozzle operating at 100 PSI .
•
From the Nelson gun chart, find the
GPM
you are pumping under the nozzle
size you have in the gun. The shaded block under the 1.56” ring nozzle
column tells you that the gun is flowing
500 GPM
.
•
From chart #4, determine how long it should take to cover one (1) acre, in
minutes, by crossing the
GPM
(from above) by the required application of
1.25
”. The shaded block tells you that it should take
68 minutes
to cover
one (1) acre.
•
From chart #5, determine the retrieve rate you need to obtain the desired
application of
1.25
” by crossing the time required to cover one acre (
68
minutes
) by the lane spacing (
350 feet
). The shaded block tells you to set
the hose retrieve rate at
21 inches per minute
as a starting point.
•
The gun should be set up so that the 350 foot width is covered plus sufficient
overlap (beyond the edge of the crop) to provide adequate watering at the
edge of the field.
NOTE : Keep in mind that the charts are to be used as a guide only. Always check the
actual application amount with rain gauges to confirm that the application
amount is correct.
