Checking Wing Fold Operation

CAUTION: To help prevent severe injury or death to you or someone else:

Make sure air has been properly bled from wing-fold hydraulic system.

Keep all persons away from machine when raising and lowering wings.

Always locate machine on level ground when raising and lowering wings.

Never raise or lower wings when moving.

1. Place tractor transmission in "park" and/or set brakes, then start engine and pull back on SCV II tractor control lever (A) to retract wing fold cylinders.

2. Move SCV II tractor control lever back and forth several times while observing operation of machine. Wings should raise when lever is pulled back and lower when lever is pushed forward. If action is reversed, reverse hose connections in SCV II hydraulic coupler.

If wing fold does not operate smoothly, air may be trapped in cylinders or hoses. Refer to INSTALLING AND BLEEDING WING FOLD CYLINDERS in SERVICE section. If after bleeding, machine still does not operate properly, see your John Deere dealer.

3. After attaching and cycling cylinders, check tractor hydraulic oil reservoir. Add oil if necessary.
