John Deere® Compatible Chrome Threshing Tine Kit
Maximise your rotor's separation capacity with this premium aftermarket chrome-alloy threshing tine kit. Specifically engineered for John Deere® STS and S-Series combine harvesters equipped with Bullet™ or Tri-Stream™ rotors, these high-wear tines are essential for final material loosening before discharge.
Each kit contains three (3) extended wear chrome-alloy tines. The specialized chrome finish provides superior abrasion resistance, allowing the tines to maintain their aggressive threshing profile significantly longer than standard steel versions. This high-performance upgrade ensures your separation system remains in top condition even when processing highly abrasive or high-moisture crops.

Expert Maintenance Review
The chrome threshing tines are a premium preventative maintenance choice for growers in abrasive conditions. As tines wear and shorten, they fail to penetrate and loosen the straw mat, leading to grain being "carried over" and lost out the rear of the machine.
By maintaining full-length, aggressive tines, you ensure a high-strength separation action that maintains grain quality and reduces rotor load. Replacing these in complete sets ensures your machine stays in top condition, preventing the mid-harvest capacity drops often associated with worn threshing hardware.
Installation Tip: Hardware Replacement
This kit is supplied with high-tensile Class 10.9 M10x60 flange bolts. When replacing threshing tines, never reuse old or stretched hardware. The high rotational speeds of the rotor require a high-performance mechanical bond; using the provided new bolts ensures the tines remain securely fastened and the rotor balance is maintained throughout the season.
