Description
When you need a smooth finish on your disc harrow work, this 24-inch smooth disc blade from Osmundson delivers the level seedbed preparation that sets you up for success. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. While your notched blades up front handle the heavy residue cutting, this smooth blade works behind them to create that fine, level surface you’re looking for.
What You’re Getting
- 24-inch diameter smooth edge design for precise soil finishing and leveling
- The 1/4-inch thickness provides the beef needed for long service life
- 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
- 2.80-inch concavity creates the aggressive soil-throwing action that buries residue and levels fields
- Single punch mounting for 1-3/4 inch round axles – direct replacement for worn blades
Built for Real Farm Work
This blade fits disc harrows with 1-3/4 inch round axles, commonly found on mid-size tillage equipment used for primary and secondary field preparation. Whether you’re working corn ground in spring or preparing winter wheat stubble for the next crop, this smooth blade excels at creating the fine, level finish needed for optimal seed placement and emergence.
Made to Last
Osmundson doesn’t mess around with blade materials. No fancy coatings here – just quality steel that works. The Boron steel construction handles the constant impacts and abrasion of tillage work while maintaining its cutting edge season after season.
Installation Notes
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 plenty of service life ahead when properly maintained.
