GX20250 Mower Blades for John Dee re 48 inch Deck, GY20568 High Lift Blades Compatible with John Dee re L120 L130 L2048 L2548 2148HV 48" Deck Lawn Tractor, Replace 330-619, 3 Pack

What It Is

The GX20250 is a set of three high-lift replacement blades designed for 48-inch John Deere lawn tractor decks, optimized for superior grass clipping discharge and bagging performance in residential mowing.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck (measure deck width from outside to outside). This set fits John Deere L120, L130, L2048, L2548, and 2148HV models, plus others using the same deck. Cross-reference your OEM part number: these replace 330-619 and GY20568. Measure your existing blade length (should be ~18.5 inches), center hole diameter (commonly 1 inch), and thickness (0.25 inches) to ensure match. Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• High-lift design increases airflow for better bagging and side discharge, but creates more drag—may strain smaller engines or reduce run time.
• Installation is straightforward (single bolt per blade), but torque to 70-90 ft-lbs and use thread locker to prevent loosening.
• Quality note: aftermarket steel may dull faster than OEM; inspect after 10-15 hours of use and sharpen or replace as needed.
• Common gotcha: ensure blades are mounted with the lift wing facing upward (toward the deck) for proper airflow.

Should You Buy It

If you own a compatible John Deere 48-inch deck tractor and prioritize budget-friendly bagging or discharge performance over OEM-brand longevity, this three-pack is a solid value at ~$9 per blade—just be prepared for slightly shorter life than factory blades.
