Use hazard warning lights and turn signals when towing equipment on public roads, unless prohibited by state or local laws.

IMPORTANT:

  • Engine cannot be started while towing.
  • Never tow faster than 2 km/h (1 mph).
  • Always tow harvester using rear or front tow points.
  • A hydraulic loop (free-flowing circuit) in the ground drive system must be created to allow oil to flow without restriction through the final drives.
  • Rear final drives must have brakes released manually.

Towing a machine with a hydrostatic drive system requires looping the hydraulic circuit. To loop both ground drive pumps, perform the following:


Loop the Hydraulic Ground Drive Circuit

  1. NOTE: Two connector fittings (not supplied) are required to join the hoses from the high-pressure ports of the two ground drive pumps together.

    Disconnect hoses from ports (A and B) of first ground drive pump.

  2. Connect hoses together using a connector fitting.

  3. Disconnect hoses from ports (C and D) of second ground drive pump.

  4. Connect hoses together using a connector fitting.

  5. Cap or plug open ports on hydraulic pumps.


Release Brakes on Rear Final Drives

  1. The disk brakes located in each final drive must be pressurized in order for them to be hydraulically released.

  2. Connect the two brake lines, on the back of each final drive, to a manual hydraulic pump using a T-fitting. The manual hydraulic pump is used to pressurize the disk brakes so they can perform the hydraulic release.

    A pressure of 20 bar (300 psi) must be maintained during the tow in order for brakes to remain free.

  3. Tie down and secure all loose hoses.

    NOTE: In cases of urgency where the adequate resources for preceding procedures do not exist, the front part of the final drive can be opened (Cover - releasing allen screws with a 6 mm screwdriver) and remove the first gearing assembly. This frees the machine to be towed a few meters. This first gearing assembly comes out by hand and with it all the drive oil, allowing the machine to be moved a few meters.
