Description
When your disc blades start leaving streaks instead of smooth, consistent tillage, it’s time for replacements that’ll actually cut through soil and residue instead of just pushing it around. This 20-inch smooth disc blade brings steady cutting action back to your harrow, giving you the smooth finish you need for seedbed prep without the aggressive tear-up that comes with notched blades.
What You’re Getting
- High-carbon Boron 15B26 steel heat-treated to 46-52 Rockwell hardness for the perfect balance of edge retention and impact resistance
- Combo hole design that works with multiple spool and spacer setups – no hunting for special hardware
- Standard 1.88-inch concavity that cuts clean while moving soil effectively without excessive draft
- 9-gauge thickness that holds up to rocks and roots without being so thick it won’t flex over obstacles
- Factory-sharp edge that’s ready to work right out of the box
Built for Real Farm Work
This blade fits disc harrows with the common 1 square x 1-1/8 square axle configuration found on many mid-size tandem and offset disc harrows. Smooth blades like this one work great on rear gangs for finishing passes, breaking up clods and leveling the seedbed without leaving the rough finish that notched blades can create in lighter soils.
Made to Last
This Boron steel maintains perfect hardness – tough enough to hold an edge through acres of tillage work, but not so brittle it’ll shatter when you clip that hidden field stone. The smooth edge design reduces stress concentrations that can cause cracking, so you’ll get consistent performance season after season.
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 done when they’ve lost 3-4 inches. The combo hole gives you flexibility with spacing, but check that your current spools and washers are in good shape while you’ve got things apart.
