Prepare Hydraulic System—Tractors With Electro/Hydraulic SCV Controls

1. 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.

   Check hydraulic oil level. Fill if necessary.
