Ordering the right blade for your Great Plains Cavalier
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 — 1-1/8" sq is standard for the Great Plains Cavalier, but confirm on your machine.
- Edge profile — notched (aggressive residue-cutting front-gang blades). Match what came off, unless you're intentionally changing edge to change residue behavior.
If any of those are unclear, call 515-686-5575 and we'll match a blade from stock.

Frequently asked questions
What size disc blades fit the Great Plains Cavalier?
The Great Plains Cavalier (Compact Disc) typically runs 18", 20" blades depending on the gang and configuration. Confirm by measuring the outside diameter of a worn blade on your machine, or call 515-686-5575 with your model serial and we'll match it.
Are these OEM Great Plains blades?
No — these are premium replacement disc blades manufactured to fit the Great Plains Cavalier. 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 compact disc like the Great Plains Cavalier, the standard configuration is notched (aggressive residue-cutting front-gang 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.
