8TEN LawnRAZOR Blade for John Deere LA130 Z255 X165 E170 155C 48" Deck GX21785 AM141036 (High Lift) 3 Pack

What It Is

The 8TEN LawnRAZOR High Lift Blade (3-pack) is a replacement blade set designed for 48-inch cutting decks on select John Deere lawn tractors and zero-turn mowers. Its high-lift profile increases airflow to lift grass for a cleaner cut, making it ideal for bagging or discharging in tall or damp conditions.

Fitment & Compatibility

Before buying, confirm your deck is a 48-inch model. This blade fits John Deere models including LA130, LA140, LA145, LA150, LA155, LA165, X165, X155C, Z225, Z235, Z245, Z255, E170, E180, and E100 series. It replaces OEM part numbers GX21785 and AM141036. Measure your blade length (should be 20 inches from tip to tip) and center hole diameter (usually 1 inch). Ensure your deck uses a three-blade system—not a two-blade or stamped deck. Check spindle orientation; this blade is symmetrical, so it fits standard spindles.

Key Things to Buy

• Quality: LawnRAZOR blades are heat-treated and hardened, offering durability comparable to OEM. Expect a slight weight difference (lighter than OEM) but consistent cutting performance.
• Installation: Easy swap with basic tools (socket, torque wrench). Use a blade removal tool to lock the spindle. Torque bolts to 40-50 ft-lbs. No special hardware needed.
• Gotchas: High-lift blades increase engine load and can throw debris—avoid using on fine gravel or loose surfaces. They produce more noise and vibration than standard blades. Check blade balance before installing; slight imbalance can cause deck wobble.
• Packing: 3-pack covers a full deck. If one blade is damaged, you still have spares. Not compatible with 42-inch or 54-inch decks.

Should You Buy It

If you own a compatible 48-inch John Deere and frequently bag or cut thick grass, this high-lift set is a strong value at $38.95. It’s a reliable aftermarket alternative that performs close to OEM for less than half the price. Skip it if you only mulch or cut on clean, dry lawns—standard lift blades will be quieter and use less power.
