John Deere GX20249 Replacement: Compare 9 Options

How to find your model number

Check your model number before you buy a replacement for the GX20249. On a push mower the model label is usually on the back of the deck, near where the handle mounts, or under the rear grass-catcher door.

Spring maintenance

A dull blade tears grass instead of cutting it. Sharpen or replace blades at the start of the season, and replace any blade that is bent, cracked or worn thin at the tips. Balance a blade after sharpening.

Maker's part vs aftermarket: the GX20249

We did not find John Deere's own GX20249 on Amazon. 9 brands sell a mower blade listed as its replacement, including 8TEN, Aeagle, budrash, GANCO.

• Maker's own part: made and sold by the equipment or engine maker (for example John Deere, MTD or Briggs & Stratton). Usually the highest price.
• Aftermarket parts: made by other companies to the same size and fit. Usually cheaper; materials and build quality vary by brand.
• Before you buy: find your equipment's model number (see How to find your model number, above), compare the size of your old part, and confirm the fit on the product page.
