9. On left side of baler, look at knife and counternife. If an inward bow (A) is present, an adjustment will be needed.

10. Obtaining Proper Knife-To-Counterknife Contact

To obtain proper contact between knife and counterknife, first adjust counterknife to both ends as described in steps above then follow procedure below.

  • Raise counterknife to highest position using monitor-as was done for earlier steps.
  • Remove four nuts and remove brush (if not done previously).
  • Loosen four nuts that hold knife to mounting bracket.
  • Place a hand (B) near center of knife/counterknife, pull rearward on knife until knife is bowed to rear approximately 2mm (.079 in.).

    IMPORTANT: It is important to maintain straightness of knife to get good net cutoff. You must hold knife in a straight position while tightening nuts. Once bolts are tight, knife will remain straight. IF you do not continue to hold knife straight while tightening, it may return to it's original shape.

  • Tighten nuts (C) while holding knife in bowed position.
  • Recheck knife with straight edge and look down knife from the side of baler. Knife should be straight (D) or bowed rearward slightly at center.
  • Lower counterknife against knife bevel. Knife should contact at both ends and contact or have maximum clearance of .25 mm (.010 in.) (check with feeler guage) between knife bevel and counterknife.
