John Deere Mower Blade Cross Reference Chart
Posted by Outdoor Power LLC Parts Team on
Lawn tractor, zero turn or commercial walk-behind, this chart matches John Deere OEM blade numbers (GX, M, AM and TCU prefixes) to Rotary and Oregon replacements, grouped by blade length.
What's in this chart: 54 blades from 16-1/2" to 25" long. The most common lengths are 21-3/8" (16), 17" (9), 19" (8). By style: standard lift (30), mulcher (13), high lift (8). We carry a Rotary or Oregon equivalent for 54.
How to use this chart
Find your OEM number in the first column (use your browser's Find, Ctrl+F or "Find on page"), then read across for the Rotary and Oregon replacement. Not sure of your number? Look up your machine by model and serial in our machine parts lookup.
How to match a mower blade
- Start with the number. The OEM part number is usually stamped on the blade near the center hole. Clean it with a wire brush if it's hard to read.
- Length: measure straight across from tip to tip. Worn blades lose a little length, so round to the nearest standard size in the chart.
- Center hole: note the diameter (5/8", 13/16", 15/16" and so on) and the shape (round, star, 5-point or 6-point). A blade that fits the spindle loosely will vibrate and can come loose.
- Width, thickness and lift: high-lift blades bag and discharge best, mulching blades have a curved cutting edge, and low-lift blades kick up less dust in sandy soil.
Replace blades as a set so the deck stays balanced, and torque the blade bolts to the mower maker's spec. A bent blade should be replaced, never straightened.

Cross-references come from the aftermarket makers' published interchange data. Always compare dimensions with your old part before installing; machine makers sometimes change parts mid-model-year.
OEM or aftermarket?
OEM parts are the exact part your machine shipped with and the safe choice while it's under warranty. Quality aftermarket parts from Rotary and Oregon are made to the OEM dimensions and usually cost less. Many commercial fleets run OEM on drive components and aftermarket on wear items like blades, belts and filters.
FAQ
Is a Rotary or Oregon blade as good as the John Deere OEM part?
Both are established aftermarket makers whose parts are cross-referenced to the OEM number and made to the same dimensions. OEM is the safe pick while your machine is under warranty; aftermarket is a solid, usually cheaper choice after that.
How fast do you ship?
In-stock parts ship nationwide, and orders of $125 or more ship free.
What if my John Deere number isn't in the chart?
This chart only lists numbers we can supply. Search the part number in our store, or look up your machine by model and serial number in the machine parts lookup.
