John Deere® Compatible 9-Tooth Rifled Threshing Element Set (Position 2)
Optimise your threshing configuration with this high-performance aftermarket rifled threshing element set. Specifically engineered to fit Position 2 on John Deere® TriStream™ and BulletRotor™ threshing systems, this specialised kit is the professional choice for repairing worn components inside the primary threshing zone.
This premium set contains three complete units, each featuring a precision-cast, replaceable chrome-moly alloy rifled threshing element that bolts directly to its base mount. The aggressive 9-tooth rifled design is specifically configuration-optimised for maximum separation and threshing performance in small grain crops. This high-strength material selection ensures superior abrasion resistance, keeping your threshing rotor in top condition for a significantly longer service life.

Expert Maintenance Review
The **threshing elements** located in the primary rotor transition zone manage intense material pressure immediately following the product feeding system. High constant volume crops trigger ongoing abrasion, leading to rounded teeth, lost rifling profiles, and reduced threshing capacity. When these elements lose their crisp edges, unthreshed grain remains in the straw, driving up shoe losses. We recommend evaluating the tooth profile and mounting tightness during every off-season preventative maintenance check to isolate **worn components**.
Upgrading to this chrome-moly element set is an excellent path to save money on maintenance while sustaining peak harvester capacity. The material structure offers superior fatigue resistance compared to generic options, ensuring the rotor assembly tracks with balanced rotational weights, protecting expensive main bearings while giving your internal threshing cage a longer service life.
Installation Tip: Dynamic Rotor Balance
When **repairing worn components** on a rotor, always install threshing elements as a matched set of three across the rotor circumference. Installing single mixed or unmatched elements will introduce critical rotational weight variances, causing severe machine harmonic vibration at operating speeds. Clean out the base casting seats completely and torque all supplied high-tensile fasteners to factory specifications to secure a **high-strength** fitment.
