CAUTION:

Serious personal injury can result if you attempt to disconnect hydraulic hoses under pressure.

John Deere 8000/9000 and 8020/9020 Series Tractors: Place No. I SCV control in FLOAT position before disconnecting hoses to prevent a sudden accident that could cause severe injury to yourself.

CAUTION:

Do not remove or repair wing-fold cylinders or hoses with wings in folded position. This will allow air to enter fold cylinder hydraulic circuit, which will cause wing to drop rapidly when unfolded.

CAUTION: To avoid injury or death to you or others, stand clear of machine when wings are being folded or unfolded. Mechanical or hydraulic failure can allow wings to fall rapidly.

  1. Unfold wings (if applicable) and fully lower machine.

  2. Relieve pressure before disconnecting hydraulic lines.

  3. Disconnect hoses at tractor and from cylinder ports. Cover tractor outlets, cylinder ports and hose ends.

  4. Unpin cylinder(s). Check and repair as necessary. See your John Deere dealer.

  5. Install cylinders, and follow instructions for bleeding cylinders in BLEEDING HYDRAULIC CYLINDERS in this section.
