Heads up — this is a heavy-industrial blade.
Typical tandem-disc replacement blades in the 30" range run $70-$180 each. This SKU is priced higher because of its spec:
- 8mm thickness (heavy for larger-diameter offset gangs)
- 30" diameter (well above the 22-24" tandem-disc range)
- dimpled or Duraface surface for extended wear life
- specialty axle geometry (pilot bore or long-collar)
Machines that actually take this blade: heavy no-till offsets, big-frame Wishek / Rome / Case IH 496 / large industrial disks. If you were looking for standard tandem-disc blades, check the main disc harrow blades collection for the $70-180 range. Not sure which fits?
