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 to prevent overflow when wings are folded and press wheels are retracted.

1. Check hydraulic oil level. Fill if necessary.

NOTE: Four SCV outlets are required when equipped with separate fertilizer placement.

Three SCV outlets are required when equipped with mechanical down force.

2. (WING FOLD/UNFOLD) Press SCV III 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.

4. (FRAME LIFT) Press SCV I selector button (A) and turn flow control knob (B) to rabbit position.

5. Turn time detent knob (C) until display reads "4" seconds. This can be increased or decreased depending on actual time required to lift and lower machine.

6. (SEPARATE FERTILIZER PLACEMENT) Press SCV II selector button (A) and turn flow control knob (B) to rabbit position.

7. Turn time detent knob (C) until hydraulic setting is detent. This will allow the active hydraulic down pressure to function properly.

8. (AIR SEEDER FAN AND CART AUGER) Press SCV IV selector button (D) and turn flow control knob (B) to "5". Adjust flow to reach the desired rpm. Turn time detent knob until display reads "constant".
