Preparing Hydraulic System-8000 and 9000 Series Tractors
IMPORTANT: Always check hydraulic oil with seeding tool in field transport position. Do not overfill tractor reservoir or it will overflow when wings are folded and press wheels are retracted. 1. Check hydraulic oil level. Fill if necessary. |

2. WING FOLD/UNFOLD: Press SCV II selector button (A) and turn flow control knob (B) to fast (rabbit) position. 3. Turn time detent knob (C) until display reads "19" seconds. If this is not enough time to completely fold/unfold wings, the time detent button (C) may be set to constant. However, the tractor hydraulic pump will continue to operate after the fold/unfold cylinders have stopped moving. This is normal and not harmful. However, shutting off the pump by moving SCV lever to any position after lever has returned to NEUTRAL is recommended.
