Description
When your disc blades start looking more like dull wheels than cutting tools, it’s time for replacements that’ll actually slice through residue instead of just pushing it around. This 18-inch smooth disc blade brings back the precise cutting action your harrow needs, turning tough corn stalks and crop residue into properly sized pieces that’ll break down over winter instead of causing problems at planting time.
What You’re Getting
- Heavy-duty 9-gauge boron steel construction that handles the hardest field conditions
- Combo hole mounting system accommodates various axle configurations for versatile application
- Standard 1.63-inch concavity provides the right balance of cutting and soil mixing
- 46-52 Rockwell hardness rating means these blades stay sharp longer and wear evenly
- Precision manufacturing ensures proper balance and smooth operation at working speeds
Built for Real Farm Work
This blade fits disc harrows and tillage equipment using 1-1/8 inch square by 1-1/4 inch square axle configurations. Whether you’re running a compact utility disc behind your smaller tractor or working with medium-sized tillage equipment, this blade delivers consistent performance across various soil types and residue conditions. The smooth edge design excels at final tillage passes and seedbed preparation.
Made to Last
The boron 15B26 steel construction with 46-52 Rockwell hardness means these blades can handle rocks, roots, and years of abrasive soil contact. The blade edge stays sharper longer, and you’ll get good service life if maintained properly – most blades are ready for replacement when they’ve lost 3-4 inches from their original diameter.
Installation Notes
The combo hole design makes mounting straightforward – just match your axle configuration and secure with proper washers and hardware. When replacing blades, never mix worn and new on the same gang as the diameter difference creates uneven cutting that leaves mohawk strips. A quick tip for storage: coat blade edges with used oil to prevent rust pitting that ruins cutting ability.
