Valley Rainger Linear - Method II; Method III

40 Rainger Linear
OPERATION
Methods of Operation
Method II
Can be used on most soil types.
The system operator does not need to be present at
the completion of each step and maintenance can be
performed during the system stop.
1. The percentage timer is set at the desired appli-
cation rate and the system is started at one end
of the field and run wet (irrigating) to the other
end of the field. See Figure 40-1.
2. The system is stopped until the field has dried
sufficiently before running the system back to the
original end of the field. See Figure 40-1.
NOTE
• To reduce the possibility of creating deep
ruts, make sure the field has dried suffi-
ciently before running the system back to the
original end of the field.
3. Reverse the system direction, set the percent-
age timer, and run the system wet or dry back
to the original end of the field. See Figure 40-2.
Method III
Can be used for frequent shallow applications on
relatively sandy soils.
The system operator may need to be present at the
end of the first step if the auto reverse option is not
used.
1. The percentage timer is set at the desired appli-
cation rate and the system is started at one end
of the field and run wet (irrigating) to the other
end of the field. See Figure 40-3.
2. Reverse the system direction, set the percent-
age timer, and run the system wet back to the
original end of the field. See Figure 40-4.
NOTE
• To reduce the possibility of creating deep
ruts, the water application should be shallow
and the soil type should be sandy.
