Schumacher | Replaces MacDon 118344 | Knife Guard – Forged Black | 80640

Genuine Schumacher 80640 | forged black platform sickle guard built as a premium replacement for MacDon OEM 118344, with additional cross-reference fitment to selected Case IH, New Holland, and John Deere cutting platforms, draper headers, swathers, and mower conditioner applications.

This point-style sickle guard is commonly used throughout the main section of the sickle and is recommended for rocky conditions and on-ground cutting applications. The forged guard body is built for strength, alignment, and long wear life in demanding platform and header cutting systems.

Why point-style platform guards?

Point guards help protect the sickle section while maintaining crop flow and cutting performance in tough field conditions. The tapered guard design helps allow sickle sections to be changed without replacing the guard, reducing downtime during in-season repairs.

Important – Match the guard to the cutting system

Header and platform guards must be matched by OEM part number, guard style, bolt pattern, and machine application. Always compare your existing guard and OEM reference before ordering, especially on machines with double-drive sickles, ground-cutting platforms, or mixed header configurations.

Schumacher 80640 is commonly cross-referenced to MacDon 118344 and related platform sickle guard numbers. It is also listed against selected Case IH, New Holland, and John Deere platform applications where the same guard style is used.

The guard is double heat treated, with a hardened cutting surface in key wear areas for improved edge retention and service life. Critical dimensions are manufactured to support proper fit, sickle alignment, and quick replacement during harvest or hay cutting season.
