Ordering the right blade for your Great Plains Turbo-Chisel
To be certain the blade you order fits, verify three specs on your worn blade before ordering:
- Outside diameter — measure across the full width of the blade in inches. Blades wear from the outside in, so measure a low-wear reference blade if possible.
- Axle bore — 1" round is standard for the Great Plains Turbo-Chisel, but confirm on your machine.
- Edge profile — smooth (weight-transfer or coulter-style blades). Match what came off, unless you're intentionally changing edge to change residue behavior.
If any of those are unclear, call 641-332-4102 and we'll match a blade from stock.

Are these OEM Great Plains blades?
No — these are premium replacement disc blades manufactured to fit the Great Plains Turbo-Chisel. They match OEM dimensions, edge profile, and axle bore, and are drop-in replacements. DiscBladesForSale.com is not affiliated with Great Plains.
What edge should I use — notched or smooth?
On a chisel plow (coulter) like the Great Plains Turbo-Chisel, the standard configuration is smooth (weight-transfer or coulter-style blades). If you're running heavy corn stalks or no-till, run notched on the front gangs. If soil finish matters more than residue cut, run smooth.
