Rainger Linear 29
OVERVIEW
Guidance
There are 3 types of guidance for Rainger Linear ma-
chines, above ground cable, furrow or below ground
guidance. Either type of guidance can be used.
Above Ground Guidance (Option)
The above ground cable guidance system consists of
an above ground cable supported by posts running
parallel with the ditch or the water supply pipeline.
Two guidance boxes, attached to the linear cart
straddle the cable. See Figure 29-1.
As the machine travels through the field, the control
arms straddle the cable. If the machine moves off
course, movement of the leading control arms will
call for a steer in the appropriate direction.
Furrow Guidance (Option)
The furrow guidance system consists of two furrow
guidance boxes, arms, and skids mounted on the
linear cart. See Figure 29-2.
The skids follow a “V” shaped furrow, 4 in to 6 in
(101.6 mm - 152.4 mm) deep, running the length
of the field. See Maintenance section for detailed
instructions on furrow maintenance and construction.
When the linear cart moves away from the furrow,
the guidance arm will actuate a steer switch bring-
ing the linear cart back into the correct position. If
the steer switch should fail, a back-up safety switch
would shut the machine down.
Below Ground Guidance (Option)
The below ground guidance system consists of a
buried single loop wire running through the center of
the field, a guidance box, five antennas mounted on
the machine and an oscillator to energize the buried
wire. The buried wire emits a signal when the oscil-
lator is ON. Make sure the oscillator is turned ON
before using the machine.
The reference antenna sits directly above the buried
wire monitoring its signal. As the forward or reverse
steering antenna moves to the left or right of the bur-
ied wire it will become in phase or out of phase with
the reference antenna and cause the system to steer
back onto the wire. See Figure 29-3.
The phase loss antennas are located on each side
of the buried wire. As long as the wire stays between
these two antennas the machine will continue to run.
If either phase loss antenna crosses over the wire,
the safety circuit will open and the machine will shut
down. See Figure 29-3.
