Built for Real Farm Work
Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. This smooth blade excels in that finishing role, creating the level, uniform seedbed your planter needs. It’s also ideal for lighter tillage work where you want to size residue and level the field without the aggressive cutting action of notched blades.
Made to Last
This Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The quality construction means this blade will keep working season after season, handling the bumps and vibration that come with field work.
Good to Know
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. At 24 inches starting diameter, you’ve got good life ahead if maintained properly. A quick tip: coat blade edges with used oil to prevent rust pitting that ruins cutting ability when storing your harrow.
