7.9 | Fendt / Challenger MT

Applicable to: Supported Fendt and Challenger MT tractors using the COMMAND Fendt SCR/S4/MT valve interface.

Connection Method

COMMAND connects to the tractor’s rear SCV system using the T3H-V005 ISO Valve Adapter and the S/082 — Fendt/Challenger MT Adapter Harness.

The S/082 harness is installed inline between the tractor chassis harness and the SCV-bank harness. It connects to T3H-V005, which routes the tractor-side and valve-side CAN networks to the Tractor & Valve CAN Interface connection on the T3H-C002 ECU breakout harness.

The tractor connection is located at the rear-left of the machine. The SCV-bank harness receptacle is a flange-mounted 12-way Deutsch connector, secured to a bracket behind the SCV bank.

Installation Steps

1. Complete the machine preparation steps in Section 5.1 and isolate the tractor electrical supply.

2. Connect the 5-way plug on the S/082 harness to the tractor-side receptacle on T3H-V005.

3. Connect the 5-way receptacle on the S/082 harness to the valve-side plug on T3H-V005.

4. Locate the 12-way SCV-bank harness connection at the rear-left of the tractor.

6. Connect the tractor chassis harness plug (B) to the 12-way “Tractor” receptacle (D) on the S/082 harness.

7. Connect the 12-way “Implement PCB” plug (C) on the S/082 harness to the SCV-bank harness receptacle (A).

8. Route T3H-V005 to the COMMAND ECU and connect it to the CAN Interface connector on the T3H-C002 ECU breakout harness.

9. Ensure all connectors are fully seated and latched. Secure the harness clear of moving parts, hot surfaces and sharp edges, leaving sufficient slack to avoid strain on the connectors.

10. Keep COMMAND disarmed and restore the electrical supply.

IMPORTANT: The 12-way SCV-bank harness connection and the connection at the rear ISOBUS socket serve different purposes. Connect S/082 to the SCV-bank harness connection identified above.

Where an ISOBUS connection is required for the installation, follow Section 5.4 using the appropriate COMMAND cab or exterior breakout harness.

Tractor Valve Configuration

  1. Ensure the required tractor SCVs are enabled and unlocked using the tractor’s controls.
  2. In Level COMMAND, select Fendt SCR/S4/MT as the valve interface.
  3. Assign the required SCVs to the controlled functions, such as height and cross-slope. These assignments must match the implement’s hydraulic hose connections.
  4. Prepare the selected SCVs for external control as described below, then verify that each function operates the intended valve in the correct direction.
  5. Complete valve configuration and calibration before automatic operation.

For detailed configuration and calibration instructions, refer to the Level COMMAND Manual.

Operation Notes

To prepare the selected SCVs for automatic control:

  1. Ensure the required tractor SCVs are enabled and unlocked.
  2. Move the COMMAND Arm/Engage switch to the middle ON position to arm COMMAND.
  3. Move each selected SCV’s tractor control lever into the float position to enable external control of that valve.
  4. Press the momentary side of the COMMAND Arm/Engage switch to engage automatic control once the system is ready.

NOTE: For SCVs configured for COMMAND control, the lever’s float position enables external hydraulic control. It does not place the valve into hydraulic float.

IMPORTANT: To disengage COMMAND automatic control, press the momentary side of the COMMAND Arm/Engage switch. Move the switch to OFF to disarm COMMAND and disable its hydraulic control commands.

Before handing over the installation, verify manual valve operation and demonstrate how to enable, disengage and resume automatic control.
