GX20250 Mower Blade Compatible with John Dee re 48" Mower Deck, GY20568 High Lift Blades Fit for L120 L130 L1948 L2148 Lawn Tractors, Replace 330-619, 3 Pack

What It Is

This is a 3-pack of high-lift mower blades designed for 48-inch John Deere mower decks. They replace OEM part numbers 330-619 and GY20568, boosting grass clipping lift and discharge for better mulching or bagging on lawn tractors.

Fitment & Compatibility

Before buying, confirm your deck is exactly 48 inches wide and matches John Deere models L120, L130, L1948, or L2148. Measure blade length (should be roughly 17.5 inches), center hole diameter (about 1 inch), and thickness (0.1875 inch). These are aftermarket replacements for OEM 330-619 and GY20568, so they fit most 48-inch Edge, FastAttach, and Select Series decks on those tractors. If you have a different deck size or model (e.g., 42-inch or 54-inch), skip this set.

Key Things to Know

• High-lift design increases airflow but may cause more wear in sandy or dusty conditions—check your deck underside for debris buildup.
• Installation is straightforward: use a socket wrench to remove the old blade bolt, replace washer if worn, and torque bolt to 50-70 ft-lbs. No special tools needed.
• Common gotcha: high-lift blades can be noisier and may require more engine power—if your tractor struggles on thick grass, consider medium-lift alternatives.
• Balance check recommended: after mounting, spin the blade by hand to ensure it doesn’t wobble; unbalanced blades cause vibration and deck damage.

Should You Buy It

If you own a compatible John Deere 48-inch deck tractor (L120, L130, L1948, L2148) and need reliable, high-lift blades for better cutting and discharge at a budget price, this 3-pack is a solid choice. The high rating and low cost make it ideal for routine replacement, but skip it if your deck size differs or you prefer OEM parts for warranty reasons.
