We stock the sizes farmers and ag shops actually buy: 16", 18", 20", 22", 24", 26", 28", 30", 32" and up. Notched fronts, smooth backs, and every axle-hole shape and size the major manufacturers put on their harrows.
If you know the diameter, thickness, and hole size on your old blade, use the finder at the top of the page to jump straight to what fits. If you do not, text a photo to 641-332-4102 — we will cross-check it against our catalog before you buy. Blades ship same day when ordered by 12pm CT, free over $600, with automatic quantity discounts for ag shops stocking up before tillage season.
Common fitments include John Deere, Case IH, Krause / Kuhn-Krause, Sunflower, Great Plains, Landoll, Rome, Lemken, Amazone, Unverferth, DMI, and Yetter. Not sure whether your harrow model uses a round or square axle? That is what the concierge line is for.
Disc blades for sale — common questions
Fitment, shipping, pricing, and choosing between OEM and aftermarket.
What are the best disc blades for sale online?

Are aftermarket disc blades as good as OEM?
When manufactured to the same alloy and thickness spec, yes. We source from mills that produce OEM blades for major manufacturers. Same steel and heat treatment, without the OEM-branded price premium. See our price guide.
How do I know which disc blades fit my machine?
Measure your existing blade's diameter, thickness, and center-hole size and shape. Or text a photo of the old blade to 641-332-4102 and we'll cross-check against our catalog. Full 7-point checklist here.
Do you sell disc blade replacement kits with bearings?
Yes — order blades and bearings together and we'll match them by machine. Replacing bearings during a blade change is standard practice. See our installation guide.
