Set of replacement mower blades compatible with John Deere 48-inch cutting decks on models LA130, LA140, LA145, LA155, LA165, X140, and X165. Made by Rotary, part number GX21784. Brand new and sealed. If your grass cuts unevenly or blades are dull, nicked, or bent, these will restore a clean cut. Easy to install—just remember to disconnect the spark plug first! No UPC. Perfect for homeowners, landscapers, or anyone maintaining a John Deere riding mower. Keep your lawn looking crisp and healthy. Dull blades tear grass, leading to brown tips and disease. Swap these in at the start of the season or whenever you notice cutting quality dropping. A simple maintenance task that makes a huge difference. Reliable, sharp, and ready to go.
