Oregon Mower Blade Part Numbers Explained: 90-, 190- and 790-
If you've shopped for Oregon mower blades, you may have noticed the same blade sold under slightly different numbers. That can make it hard to tell whether two listings are the same part. Here's how Oregon's numbering works and how to match a blade with confidence.
Same blade, different prefixes
Oregon has renumbered many of its mower blades over the years. The same blade can appear with a 90-, 190- or 790- prefix, while the last digits stay the same. For example:
- Oregon 90-206 is also sold as 190-206 and 790-206 (17-7/8", 52" Hustler decks).
- Oregon 90-354 is also sold as 190-354 and 790-354 (John Deere M143520, 54" decks).
- Oregon 90-348 is also sold as 190-348 and 790-348 (John Deere M127500, 48" decks).
Different sellers may still list the older or newer number, so it's common to find all three versions online at once.
Some numbers were replaced by a new design
A few older numbers were replaced by a newer Oregon blade rather than just renumbered. For example, the older Gator Mulcher Oregon 90-395 for 42" John Deere decks was replaced by the Gator G3 blade 96-340. When a number has been superseded like this, the replacement is designed to fit the same machines.
How to be sure you have the right blade
- Match the OEM number, not just the Oregon number. The mower maker's part number (for example John Deere M143520 or Hustler 783753) is the most reliable match. Our listings show the OEM numbers each blade replaces.
- Check the key measurements: length (measured corner to corner), center hole size and shape, and width.
- If two Oregon numbers share the same last digits and the OEM numbers and measurements match, they're the same blade.
