OVERVIEW
Overhang (Option)
Typically an overhang is attached to the end of the
span pipe and used for irrigation beyond the span/
drive unit. Support ears and cables provide support
for the overhang. See Figure 23-1.
End Gun (Option)
Typically an end gun is attached at the end of the
overhang and used to increase the area irrigated
beyond the end of the machine. See Figure 23-2.
The end gun is set to cover a specified area. This
area is determined by the forward and backward
angles, which are referred to as the end gun arc set-
tings. See Figure 23-3.
Drive Towers
A drive tower is attached to the end of each span. The tower box acts as a junction box for the span cable and
supplies power to the electric motor on the center drive gearbox. The center drive gearbox drives the wheel
gearboxes. The wheel gearbox drives the tire and wheel. See Figure 23-4.
