Auger Header Parts

Our sickle section undergoes a unique heat treatment process known as Austempering, which produces a tougher and more impact resistant structure for improved harvesting performance!

Competitive parts may only receive heat treatment at the cutting edge, leaving the rest of the section vulnerable to breakage. The entire sickle section is through-hardened for high ductility and high hardness. Our Austempered Sickle Sections can be used in any harvest situation, designed and engineered to perform better than standard sickle sections.

• Austempered sickle sections are made up of substantially tougher, longer lasting material that has proven less chipping, fewer broken sections and noticeably less wear
• Unique process that involves through-hardening the entire section, versus competitors only heat-treating the cutting portion
• Substantial lab and field testing confirm worry free harvesting performance

• Distinctive MacDon box assures you of MacDon Austempered sickle sections
• Only the MacDon logo guarantees that it’s original

Designed to self sharpen as they wear, meaning your sickle sections will continue to stay sharp throughout the section life.

• Guaranteed hole spacing means your replacement sickle section will fit your MacDon perfectly every time, inconsistently spaced holes lead to premature bolt failure costing valuable downtime
• Best fit paired with your MacDon guards

Fine Section Serrations:

• 14 serrations per inch
• Provides optimal cutting characteristics in green forage, high moisture and hay crops
• Delivers a clean cut, increasing efficiency and decreasing horsepower demand during harvest
• Suitable for: Forage, Grasses, Flax and Lentils
  
  

Coarse Section Serrations:

• 9 serrations per inch
• Provides optimal balance of durability and cutting edge technology in thick stem crops
• Recommended use for on the ground applications, coarse sickle sections hold their cutting edge longer in these high debris conditions
• Suitable for: Wheat, Soybeans, Canola, Cereals and Pulses
  
  

Ultra-Coarse Section Serrations:

• 4 serrations per inch
• Provides peak cutting performance and durability in thick stemmed crops
• Recommended use for thicker stemmed crops and adverse conditions

Fully thru-hardened for toughness, MacDon Performance Parts Guards are then induction hardened in key high wear areas so they will keep their cutting edge longer.

• Fully adjustable hold down maintains tight clearance between guard and section
• Self-cleaning guards are less likely to plug the knife in tough crops such as grasses and canola

• Critical dimensions ensure a perfect fit on your MacDon machine every time, allowing for minimal downtime and quick replacements
• Perfect fit guarantees optimal cutting performance and extended wear
• Provides perfect guard fit up with cutter bar poly, resulting in proper mounting with the cutter bar

• Cutting surface is induction hardened providing targeted hardening in high contact areas, resulting in a superior cutting performance
• Harder and more durable than traditional hardening methods provides for higher impact strength and wear resistance

• Shape of the pointed guard is designed to separate the crop as well as maximize cutting surface to provide superior cutting performance
• Guard tang is engineered to maintain the proper clearance to get the most from your MacDon knife sections

Pointed Guards
The pointed guard is designed to be used when your MacDon header is low or touching the ground while cutting. This guard protects your knife sections with a reinforced rib to provide stronger impact resistance against rocks and debris.

Stub Guards
The MacDon Stub guard is designed to reveal more of the sickles cutting edge, increasing cutting abilities in tough crops such as grasses and canola. Stub guards should only be used in off-ground applications where fewer rocks and debris are encountered by the cutting components. These guards are incomplete without a top half.

• Provides extremely durable metal core throughout which allows for increased wear life and durability
• Thru hardening process results in sharper cutting edges, harder wear surface across entire guard and thinner end points, guiding crop precisely into cutting surfaces
