Speed Sensors
The Auto-Control option itself does not include a speed
sensor (as there is a choice of sensors; alternatively, the
tractor may already have a suitable sensor, and needs
only a Y-cable). If a sensor was ordered for the sprayer, it
needs to be mounted on the tractor or the sprayer. An
installation manual is included with the option.
• The radar sensor (page 55) may be mounted on the
sprayer or the tractor. Great Plains recommends trac-
tor-mounting, which has these benefits:
• eliminates a connection during hitching,
• keeps the radar well away from spray,
• may allow a clearer radar view of the ground, and;
• makes the radar available for other implements.
• The wheel sensor (page 56) must be tractor-mounted,
as the 3P300 has no wheels.
Route the harness included with the sensor to the speed
sensor input.
Electro-Hydraulic Controller
If the sprayer has the optional electro-hydraulic (E-H)
controller (page 53), it includes either a switchbox or joy-
stick controller that must be mounted in the tractor cab.
An installation manual is included with the option.
• The joystick style controller includes an assortment of
U-bolts for attaching the joystick to the hydraulic lever
that will control the sprayer boom and elevator circuit.
• The switchbox includes a mounting base. Customer-
or dealer-supplied fasteners or mounting tape are
required. Mount the switchbox at a convenient location
that does not obstruct the view of the highway or key
tractor and implement functions.
Route the harness to the hitch.
Connect power leads to a 12Vdc source. Color code is:
Red: Positive (+)
Black: Negative (-) and ground
If possible, connect to tractor power on the device side of
a main power switch or relay, so that there is no risk of E-
H solenoids consuming battery power when not in use.
