A - Hitch Tube

B - Planting Unit Frame

Periodically check that hitch tube (A) and planting unit frames (B) are parallel to the ground during operation.

  1. IMPORTANT: If tractor has Category 4 drawbar, it must be used with a Category 4 clevis on planter. If tractor has Category 5 drawbar, it must be used with a Category 5 clevis on planter. (See INSTALL PROPER DRAWBAR CLEVIS.)

    NOTE: Adjustments are more accurate when performed in field conditions.

    NOTE: If center frame of machine is higher or lower than wings, rephase hydraulic lift system. Raise machine and hold SCV lever for several seconds to rephase. If center frame on machine is lower than wings after rephasing see ADJUST MAIN FRAME HEIGHT in Service section.

    Set adjustable down force system to zero pressure.

  2. Lower machine on level ground.

    Place planter in parking position, see Detach Planter section. Disconnect clevis from tractor.


  7. NOTE: Turn clevis over for minor adjustment. Move clevis to a new hole for major adjustment.

    Reposition clevis (A) so hitch becomes parallel to ground when reattached to tractor.

  8. IMPORTANT: Cap screws must be tightened before load is placed on hitch to obtain accurate torque values.

    Tighten clevis cap screws (B) to specification.
