John Deere® Compatible Heavy Duty Bisalloy Separator Grate Assembly
Enhance your machine's separation efficiency with this premium C&M Australian-made heavy duty separator grate assembly. Specifically engineered for John Deere® STS and S-Series combine harvesters, this single-piece grate provides a superior alternative to the standard multi-part bolt-together units.
Manufactured in our Griffith factory from Bisalloy 400 wear plate, both the frame and the finger inserts are built to withstand extreme abrasive conditions. This high-strength, single-piece construction eliminates the common issue of loose hardware and frame shifting found in traditional grates. By utilising extended wear materials, this assembly ensures your threshing and separation system stays in top condition, maintaining maximum grain retention and throughput.

Expert Maintenance Review
The separator grates are the final stage of the separation process before material enters the discharge area. Over time, the finger inserts can suffer from severe abrasion, leading to rounded edges that fail to catch and separate grain from the straw mat. We recommend inspecting the "sharpness" and profile of the fingers during every preventative maintenance check to prevent unnecessary rotor loss.
Upgrading to this Bisalloy 400 assembly is a strategic choice to **save money** on long-term maintenance. The high-performance wear plate maintains its profile much longer than standard steel, and the single-piece frame design ensures the grates remain perfectly aligned with the rotor. This keeps your separation system in top condition and providing a significantly longer service life than original hardware.
Installation Tip: Complete Set Replacement
For the most consistent separation performance, we highly recommend replacing all four (4) separator grates as a complete set. This ensures a uniform distance between the rotor elements and the grate fingers across the entire separation zone. Using new high-tensile hardware will maintain a high-strength mechanical connection to the combine frame.
