Expert Maintenance Review
The sickle knife sections function as the absolute front-line contact point in the product feeding system. Continuous high-speed operation through dust, field sand, and heavy vegetation triggers ongoing abrasion, leading to chipped teeth, dull serrations, and severe edge rounding. When individual sections dull, they begin to rip or chew the crop rather than cleanly shearing it, driving up cutter bar vibration and header grain loss. We recommend evaluating the section serrations and checking for missing rivets during every pre-harvest preventative maintenance window.
Upgrading to this high-performance aftermarket section is an excellent choice to save money on major maintenance overhauls. Replacing dull or missing sections at the first sign of crop wrapping preserves the integrity of your knife guards, lowers the structural load on your main wobble box yokes, and ensures your cutting system stays in top condition.
Installation Tip: Rivet or Bolt Torque
When repairing worn components across the knife back, ensure the section mounting surface is perfectly clean of old crop scale and rust before fastening. If using sickle bolts, torque to exact manufacturer specifications to prevent loosening under heavy crop pressure; if using rivets, ensure the head is swaged down flush. Any lateral movement will cause the section to chatter, accelerated abrasion, and damage the underlying knife guard ledgers. Check your complete knife head assembly tracking prior to full speed operation.
