What It Is

This is a set of three low-lift replacement blades designed for 38-inch decks on John Deere lawn tractors (GT235, LX188, LT133, and others) and compatible Lesco models. Low-lift blades are ideal for dry, sandy soil or light mulching, producing less dust and requiring less engine power than high-lift blades.

Fitment & Compatibility

• Deck size: Must be exactly 38 inches; measure deck width before ordering.
• Model fit: Fits John Deere GT235, GT242, LX188, STX38, LT133, S92, LT150, LT155, SRX95, LX172, LX173, LX176, LX178, SX95, LT166, 111, 116, 160, 165, 170, 175, and Lesco 050536. Not for 42-inch or 48-inch decks.
• OEM cross: Replaces OEM John Deere AM100946 and M82408, plus Lesco 050536.
• Measurements: Blade length ~18.5 inches, center hole 5/8 inch diameter, offset 0.5 inches. Verify blade thickness (approx. 0.2 inches) matches your deck spindle.
• Check spindle: Ensure your deck uses three blades (not two or four). Inspect blade bolts for wear; replace if damaged.

Key Things to Know

• Low-lift vs. high-lift: These won’t throw grass as far or bag as well in wet or tall grass. Best for dry conditions or mulching kits.
• Installation: Easy with basic tools—socket wrench and torque wrench (recommended 50-60 ft-lbs). Use thread locker on bolts if not pre-applied.
• Balance: Aftermarket blades may need balancing out of the box. Use a blade balancer to avoid vibration and spindle wear.
• Durability: Most users report average lifespan (1-2 seasons with normal use). Not hardened steel; avoid hitting rocks or roots.

Should You Buy It

Buy this if you own one of the listed John Deere or Lesco 38-inch decks and mow dry, light grass where dust control or lower power draw matters. Skip it if you need high-lift blades for bagging or wet, thick grass—those require a different blade profile. At $24.64, it’s a budget-friendly direct replacement for OEM blades, but check balance before installing.
