B-Float Spring Setting Dimension

  

NOTE: If equipped with hydraulic pickup lift; Remove cap screw from base end of cylinder (left-hand side) to gain access for spring adjustment.

Dimension (B) is an initial float spring setting for pickup tooth-to-ground clearance of 25-50 mm (1-2 in.) with wheel spindles in the normal position. (See WHEEL SPINDLE POSITIONS in Preparing the Baler section.)

More spring force will be 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 BALING SHORT, DRY, SLICK CROPS in Operating the Baler section.)

Less spring force will be needed if:

  • The pickup does not lower completely 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 BALING CORNSTALKS in Operating the Baler section.)

1. Loosen jam nut (A).

IMPORTANT: Any dimension less than 60 mm (2-3/8 in.) at the right-hand spring will stretch or weaken the spring.

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