Ordering the right blade for your Case IH RMX 370
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 — 1-1/4" sq, 1-1/2" sq is standard for the Case IH RMX 370, but confirm on your machine.
- Edge profile — notched fronts + smooth rears (typical tandem setup). 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.

What edge should I use — notched or smooth?
On a heavy disc harrow like the Case IH RMX 370, the standard configuration is notched fronts + smooth rears (typical tandem setup). 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.
