Be alert and away of surroundings.
Do not operate the CNH-JD Bridge system while under the influence of alcohol or an illegal substance.
Remain in the operator’s position in the machine at all times while the CNH-JD Bridge system is engaged.
Determine and remain a safe working distance from other individuals. The operator is responsible for disabling the CNH-JD Bridge system when a safe working distance has been diminished.
Ensure the CNH-JD Bridge is disabled prior to starting any maintenance work on the machine or parts of the CNH-JD Bridge system.
Follow all safety instructions from the CNH system as well as the JD system!
The CNH-JD Bridge must only be used in the field, never on the street!

Verify that all cables and connectors are not going over sharp edges and are not pinned, as this could cause power shortages and/or malfunctions.

Introduction
Congratulations on your purchase of the CNH-JD Bridge. The CNH-JD Bridge is designed to bridge the communication between a Case or New Holland Quadtrac (canbus autosteer ready) and a John Deere display (1800, 2600, 2630 or 4640). This allows a JD display to create maps in the John Deere format and also provides straight AB-Line autosteer. The operator uses the JD display to create AB-lines. The current position is determined by a John Deere receiver and all this information is used by the CNH-JD Bridge to create steering instructions for the tractor. All conditions for autosteer such as minimum speed, steering enabled etc. must be met by the CNH system before the autosteer engage option in the tractor can be activated.
NOTICE
This manual is not intended to replace the manuals for the tractor or the John Deere system. The operator must read and understand the manuals and instructions of these systems, before using the AgraGPS CNH-JD Bridge.

Installation of the CNH-JD Bridge

Note: If you need to verify that your Caser Quadtrac is a „canbus“ steered machine, please check for a build-in wheel angle sensor at the articulation point! If the wheel angle sensor shown below is installed on your machine, your quadtrac is canbus steered!

Step 1: Mounting the CNH-JD Bridge The CNH-JD Bridge is installed in the right back corner of the cab.
The plastic cover can be lifted enough to access the required connectors and there is space for the Bridge box at the bottom.

Now remove the door latch which still holds the plastic cover in its place. Once the door latch is off, carefully lift the plastic from the cab pillar. AGRA GPS CNH JD Bridge for a Quadtrac can based steering - cover

Find the connector labelled C602 behind the panel.
Open it and insert the provided AgraGPS harness.
Note: It is sometimes also called the display connector! If you do not have a display you may only see one open connector. If a display cable exists you have to open the connection and insert the AgraGPS connectors.

The 4-pin deutsch insert into the C611M and 611F connectors. This will integrate yourJD receiver and display into the ISO Harness of your tractor.

Run the cable to the bottom to connect to the CNHJD Bridge. There is enough space behind the platic panel to hide the cable.

Now run the the display cable though the oval opening.
The 12-pin deutsch connectors fits through that opening and should be coming out at the bottom of the plastic panel together with the first cable from the connector.

Once you have routed both cables to the bottom, connect them with the Bridge. Finish the Bridge part of the install by placing the Bridge in the opening and routing the display cable to your JD display mount. AGRA GPS CNH JD Bridge

You can find the navcontroller at the bottom of the passenger seat. Remove the passenger seat cushion.Then fold the floor cover back to remove some more nuts. Last remove some plastic mounts between passenger and driver seat. You should now be able to lift the passenger seat enough to undo the2 connectors into the nav controller.
They are secured with an allen key bolt, a 40-pin and a 24-pin connector. Simply disconnect them.

Step 2: Mounting the JD receiver
The mounts for the JD display and receiver are NOT part of the CNH-JD Bridge.
The JD mount can easily be bolted to the metal bracket provided on the roof of the CNH Quadtrac.
Using the short 12-pin adapter cable, the JD receiver is connected to the 12-pin deutsch in the CNH tractor roof.
DO NOT CONNECT THE John Deere GPS receiver without the adapter cable to the CNH roof outlet!!
