    When first operating the Model JH7020 or JH9020 Leveling System in hillside conditions, begin operation on gradual slopes and work up to more severe slopes only after you have determined that rear axle weighting is appropriate for downhill maneuvers. The first indication of insufficient rear axle weighting is sluggish or unresponsive steering while traveling down hill.

    Hydraulic Settings Refer to the Hydraulic Safety section for precautions regarding the hydraulic system. The Model JH7020 Leveling System uses an auxiliary gear pump and single-station manifold for its leveling and a separate header trim manifold. The Model JH9020 Leveling System uses hydraulic flow from the closed center hydraulics of the combine.
