SKU: SMA-114-241405FSP Crimp Center Disc Blade for CaseIH RMX370 TrueTandem 370 and EcoloTiger Disc Harrows

When you're working heavy residue or need to size and position crop material just right, a standard disc blade sometimes doesn't cut it. That's where this crimp center blade comes in handy. The 8-inch crimp center creates extra turbulence and mixing action, breaking up clods and distributing residue more evenly than a smooth blade alone. It's built specifically for the front gangs where the heavy lifting happens.

What You're Getting

• Boron 15B26 steel construction that's hard enough at 46-52 Rockwell to hold an edge through tough conditions, but won't shatter on field stones
• Quarter-inch thickness provides the durability needed for long service life in demanding tillage work
• Shallow concavity design that penetrates well without being too aggressive for finishing work
• Single punch mounting hole that's a direct replacement for worn blades

Built for Real Farm Work

This blade is engineered specifically for Case IH RMX370 and TrueTandem 370 disc harrows, plus the 870/875 EcoloTiger and RMX 790 models. These are workhorses that handle everything from corn stalk residue to cover crop termination, and this blade gives them the cutting and sizing action they need to do the job right the first time.

Made to Last

Osmundson doesn't mess around with blade materials, using Boron 15B26 steel that maintains the perfect hardness range for field conditions. The shallow concavity won't wear as quickly as deeper blades in rocky soils, while still providing the soil movement you need for proper seedbed preparation.

Good to Know

This is a direct replacement that mounts with the same hardware as your original blade. The crimp center design works best on front gangs where you want aggressive residue cutting, while smooth blades on the rear gangs provide the finishing action. Check your blade diameter regularly - when they've lost 3-4 inches, it's time to replace them for best performance.
