SKU: SMA-114-16090102N Notched Disc Blade for Disc Harrows with 7/8 Square by 1 Square Axle

When your disc harrow's cutting action starts getting lazy and you're leaving too much residue on the surface, it's time for blades that'll actually slice through crop debris instead of just rolling over it. Notched blades excel in heavy residue but can be too aggressive in light soils or minimal trash conditions. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing.

What You're Getting

• 16-inch diameter blade built from Boron 15B26 steel with 46-52 Rockwell Scale hardness for long-lasting cutting edge
• 9 gauge thickness (3.5mm) gives you the right balance of durability without being too heavy
• Notched edge design creates aggressive cutting action that slices through tough stalks and matted residue
• Combo hole design fits 7/8 square by 1 square axle configurations for versatile mounting options
• Standard concavity specification moves soil properly while maintaining good penetration

Built for Real Farm Work

This 16-inch blade is sized right for smaller disc harrows and offset discs used on farms where you need to work around obstacles or in tighter spaces. Whether you're chopping corn stalks before planting soybeans or working down wheat stubble, this blade handles the mix of cutting and soil movement that keeps your seedbed prep on track.

Made to Last

The Boron steel construction with heat treatment to 46-52 Rockwell hardness means these blades hold their edge longer than basic carbon steel options. The 9 gauge thickness gives you plenty of material to work with as the blade wears, so you'll get good service life even in rocky or abrasive soil conditions.

Good to Know

The combo hole design means this blade works with both square mounting setups, so check your axle size before ordering. Check for elongated holes from wear - loose blades wobble and wear prematurely. When storing disc harrows, coat blade edges with used oil to prevent rust pitting that ruins cutting ability. Track your blade wear by measuring diameter annually; most blades are shot when they've lost 3-4 inches.
