Overview
Installation Instructions
AutoTrac Universal system requires the GreenStar
system to operate. The two systems consist of the
following components:
• GreenStar
– Receiver
– Processor
– Display
– Harness
• AutoTrac Universal
– AutoTrac Universal Steering Wheel
– Shaft Bushing
– AutoTrac Universal Harness
– Anti-Rotational Device
The GreenStar System
This system consists of a receiver, a processor, and a
display, connected by a harness. On the new GS2
system, the display and processor are combined into a
single unit. The GreenStar system is the backbone for
many processes such as recording harvest yields,
setting planter and chemical application rates, and
mapping acres covered. Because the GreenStar
system is utilized by so many different processes, it is
sold separately from the AutoTrac Universal Steering
Kit. Installation of the GreenStar system is dependent
on the vehicle it is being installed on. Newer John
Deere vehicles come with the harness already
installed.
AutoTrac Universal System
This system is an easy-to-install guidance system that
works similar to the integrated system, but instead of
directly controlling the hydraulics that steer the
machine, the AutoTrac Universal system turns the
steering wheel, guiding the machine using the same
mechanisms that a person would.
Because AutoTrac Universal isn’t integrated into the
steering system:
• It is compatible with a large number of different
machines. See your John Deere dealer for a list of
approved platforms.
• Accuracy is affected by wear on any part of the
steering system.
