Case-IH®, MacDon® & New Holland® Compatible Complete Knife Guard Kit - 40' Double Drive

Restore clean, even cutting performance across your 40-foot double-drive draper header with this premium aftermarket complete knife guard kit. Designed for compatible Case-IH®, MacDon® and New Holland® cutting platforms, this kit supplies the key guard layout required to refurbish worn cutter bar components from end to end.

Knife guards are a critical wear point in the cutter bar assembly. When guard points, slots and ledger surfaces wear unevenly, the sickle can start dragging, chewing crop and increasing load through the knife drive. This complete 40ft double-drive kit helps return the guard line to a consistent working profile, supporting cleaner crop entry, reduced vibration and reliable feeding into the draper platform.

The C&M Difference

Collier & Miller supplies quality aftermarket parts that are selected for fit, practical value and reliable performance in Australian farming conditions. This complete knife guard kit gives operators a straightforward way to repair worn components across the full cutter bar rather than replacing individual guards one at a time and leaving uneven wear behind.

Our team understands agricultural machinery, header front wear points and the importance of getting the right parts before harvest pressure hits. We check component references and fitment suitability so customers can order with confidence and keep their cutting platform in top condition with a strong price-to-performance balance.

Expert Maintenance Review

The cutter bar is the first contact point in the crop feeding system. In abrasive paddock conditions, guard points and ledger surfaces are constantly exposed to sand, grit, crop residue and sickle friction. Once the ledger edge rounds off, the knife sections can tear rather than shear the crop, leading to head chatter, crop shatter, uneven stubble and extra load through the knife drive yokes.

During pre-season maintenance, inspect the full guard line for tip alignment, slot wear, damaged points, rounded ledger surfaces and uneven knife clearance. A complete guard replacement can help save money over time by reducing mixed wear heights, protecting sickle sections and lowering the chance of binding or shock loading through the drive area.
