John Deere® Compatible High Wear Threshing Element Kit (Position 2)
Optimise your threshing and separation efficiency with this premium aftermarket high wear threshing element kit. Specifically engineered for popular John Deere® combine harvesters equipped with TriStream™ or Bullet™ rotors, this kit is the professional solution for repairing worn components positioned directly on the mid-section surface of the front cone.
This high-performance kit contains a matched set of three replacement elements that are precision-manufactured and fully hardened to handle the intense mechanical pressure of processing high-volume crops. Suitable for both grain and corn harvesting, this extended wear setup offers superior abrasion resistance compared to standard parts. This strategic refurbishment ensures your rotor remains in top condition, delivering excellent material breakdown while offering a significantly longer service life.

Expert Maintenance Review
The threshing elements inside the rotor cone mid-section operate at the high-friction interface following the initial product feeding stage. Constant exposure to moving material, abrasive crop dust, and heavy grain volumes causes standard factory elements to experience extreme abrasion thinning and lose their profile. When edges round off, separation efficiency drops, increasing threshing losses out the back. We recommend examining the element tooth edges and checking for structural wear during every off-season preventative maintenance window.
Upgrading to this hardened high wear element kit is an excellent investment to save money on long-term running costs. The premium hardened shell maintains its structural sharpness much longer than standard steel elements, maintaining perfect material agitation across the concaves and keeping your complete rotor assembly working in top condition.
Installation Tip: Balanced Weight Alignment
When repairing worn components on a TriStream™ or Bullet™ rotor, it is critical to replace all three elements at Position 2 together using the provided hardware. Mixing new elements with worn parts creates an immediate rotational mass imbalance, inducing severe harmonic vibrations that can cause structural fatigue or destroy the primary rotor bearings. Thoroughly clear the mounting surface scale before bolting down to secure a flat, high-strength fitment.
