    A - Depth Adjusting Handle

    B - Nut

    C - Pin

    D - Clevis

    E - Dimension

    F - Dimension

    Position each depth adjusting handle (A) at desired seed depth. See ADJUSTING SEED DEPTH in this section.



  2. There are two ways to increase opener down-pressure to compensate for track left by tire. First, tighten nut (B) in 6 mm (1/4 in.) increments until desired penetration is achieved. Second, remove pin (C) and turn clevis (D) to increase length of spring assembly.

    Initial Dimensions Are:

     

    Dimension E

    Dimension F

    Short

    241 mm (9.5 in.)

    351 mm (13.8 in.)

    Long

    279 mm (11.0 in.)

    446 mm (17.6 in.)

    When lengthening spring assembly by 6—13 mm (1/4—1/2 in.), install jam nut above clevis to lock clevis to bolt. Lengthening spring bolt assembly 6 mm (1/4 in.) will lower opener 19 mm (3/4 in.). Do NOT lengthen assembly more than 13 mm (1/2 in.). Lengthening assembly will decrease opener ground clearance when openers are raised.
