Installing Tractor Electronic Steering Components
Compatible Tractors
New 3PYP planters include hydraulic steering, which
requires mounting a sensor in the tractor steering gear or
if available, using existing tractor sensors. ISO compati-
ble wheel tractors and track tractors with factory installed
(not aftermarket) auto-steer ready components use the
electronic steering sensor module and harnessing. Non
ISO compatible and those tractors without factory
installed auto-steer components require the linear sen-
sor in the steering gear.
Brackets and instructions are included for the tractor
brands and models listed at right.
The tractor must otherwise also meet the requirements
listed under Specifications and Capacities, see “Appen-
dix” on page 58.
If you do not have one of the brands and models listed
above, consult your Great Plains dealer.
At time of publication, this 3PYP steering system is not
compatible with articulated tractors.
Seed cart steering is hydraulically controlled to match
steering of the tractor based on one of the following:
• the value of the steering angle signal on the CANbus,
• the value of the signal as transmitted from the steering
sensor.
You will find one of the following three major subassem-
blies installed on your tractor:
1. the electronic steering module connected to the trac-
tor’s implement CAN network
2. the electronic steering module connected directly to
the tractor, factory installed steering angle sensor
Sensor installation is normally completed by the Great
Plains dealer prior to delivery. If it was not, this Pre-Deliv-
ery manual includes tractor steering sensor installation
instructions.
Refer to Figure 85
Do the following to setup the cab steering switch
console
which controls operation and calibration of the
steering system:
Mount the switch box in any convenient location that
allows observation of fault indications, and does not
obstruct safe operation of the tractor.
Route the main harness to the hitch, where it mates
with the Steering ECU harness.
