More spring force is needed if:

• Operating at pickup tooth-to-ground clearance above 50 mm (2 in) with wheel spindles in the normal position.
• The baler has been lowered at the wheel spindles to improve feeding. (See Bale Short, Dry, Slick Crops in Operating the Baler section.)

Less spring force is needed if:

• The pickup does not lower to desired operating height.
• The pickup bounces too much and leaves crop.
• The baler has been raised at the wheel spindles to improve feeding. (See Bale Cornstalks in Operating the Baler section.)

1. Loosen lock nut (A).

2. Any dimension less than 60 mm (2-3/8 in) at the right-hand spring stretches or weakens the spring.

   Tighten screw into spring plug until dimension (B), between the spring plug and the spring anchor is attained.
