Configuring Tractor for GPS/Radar
Operator would like to use GPS ground speed signal as the true ground speed signal.


Situation or Problem

The operator wants to use the speed signal from the GreenStar™ system for true ground speed. This speed signal can be used as the radar signal, if the tractor is not equipped with radar.

Solution Steps

Tractors equipped with radar must be re-configured when switching to GPS receiver as the true ground speed input signal.

To configure tractor:

  1. Remove screw (A) and CommandCenter (B).
  2. Inside right-hand console locate one wire lead marked "GPS" and one marked "Radar".
  3. Remove radar plug (C) from wiring connector (E).
  4. Remove GPS plug (D) from dust cap (F).
  5. Install GPS plug into connector and radar plug into dust cap.
  6. Install CommandCenter™with previously removed screw.

Tractors not equipped with radar, but wanting to add a GPS signal require two controller addresses to be changed. Contact your John Deere dealer and reference Dealer Technical Assistance Center (DTAC) Solution 78614.

Note: GPS radar is not recommended for use with AutoLoad™ equipped tractors.
