GX20250 GY20568 Mulching Blades Fit for John Deere 48 inch Mower Decks L120 L130 L120 L130 L2048 L2548 Sabre 1642HS 1742HS Lawn Tractors(3 Pack)

What It Is

This is a 3-pack of 48-inch mulching blades designed for John Deere and Sabre lawn tractors. They replace OEM part numbers GX20250 and GY20568, cutting grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify three things: deck size (must be 48-inch), deck model (L120, L130, L2048, L2548, Sabre 1642HS, 1742HS), and blade dimensions (OEM replacements measure 20.5" length, 2.75" width, 0.25" thickness, with a 0.75" center hole and 0.625" offset). These blades are aftermarket, not genuine John Deere, but match OEM specs. They will not fit 42-inch or 54-inch decks. Check your mower’s deck model number (stamped on the deck) for exact match.

Key Things to Know

• Quality: Made from heat-treated steel. Most users report they hold an edge well for a season of regular mowing. Not as thick as OEM, but adequate for residential use.
• Installation difficulty: Easy (15-20 minutes). Use a torque wrench to tighten blade bolts to 50-60 ft-lbs. Always disconnect spark plug before lifting deck.
• Common gotcha: These are mulching blades (curved, with extra cutting edges), not standard lift blades. They will not discharge clippings well if you leave the chute open—use the mulch plug or kit.
• Balance: Each blade is marked for balance. If your mower vibrates after install, check blade balance with a simple nail-in-wall test.

Should You Buy It

Buy this if you have a 48-inch John Deere or Sabre tractor and want affordable replacement mulching blades for regular residential mowing. Skip if you need OEM-grade thickness for heavy commercial use, or if your deck is a different size. At $28.99 for three blades, it’s a solid value for homeowners who want fine clippings without bagging.
