Checking Wing-Fold Operation

causym CAUTION: To prevent serious injury or death:

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

Stand clear of 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. Start engine and pull back on SCV II lever (A) to retract wing-fold cylinders.

2. Move SCV II lever back and forth several times while observing machine operation. 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 couplers.

If wing-fold does not operate smoothly, air may be trapped in cylinders or hoses. (See INSTALLING AND BLEEDING WING-FOLD CYLINDERS in Service section.) If after bleeding cylinders, 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.
