8TEN LawnRAZOR Blade Set for John Deere Lesco 110 112 120 140 312 314 38 inch Deck M41237 050321 (Notched High-Lift)

What It Is

The 8TEN LawnRAZOR Blade Set is a set of two notched high-lift replacement blades designed for 38-inch cutting decks on select John Deere and Lesco commercial walk-behind mowers. These blades are intended for users who need improved grass lift and discharge, especially in thick or wet grass.

Fitment & Compatibility

• Deck size: 38-inch. Measure your deck width to confirm; these blades are not for 36-inch or other decks.
• Model fit: Fits John Deere Lesco 110, 112, 120, 140, 312, 314 with a 38-inch deck. Also fits older Lesco models using OEM part numbers M41237 or 050321.
• OEM cross-reference: Replaces John Deere M41237 and Lesco 050321. Verify your current blade’s part number matches these.
• Measurements: Blade length is 19.5 inches, center hole is 5/8 inch, and the blade is 2.5 inches wide. Check your spindle bolt size (typically 5/8-inch) and blade thickness matches your deck.
• Notched design: The notch is for spindle clearance on certain decks—confirm your deck uses notched blades before buying.

Key Things to Know

• High-lift design: Produces strong airflow for bagging or discharge but increases engine load and wear on spindles. Not ideal for mulching.
• Installation: Straightforward—remove old blades, clean spindles, and torque to 50-70 ft-lbs. Use a blade lock or wrench. No special tools required.
• Quality: LawnRAZOR is a budget aftermarket brand. Expect moderate durability; may need sharpening more often than OEM blades if used in sandy or tough conditions.
• Common gotcha: The notched cutout is specific to certain decks. If your deck uses straight blades, these won’t fit. Also, check that your deck has two blades—some 38-inch decks use three.

Should You Buy It

Buy this set if you need an affordable replacement for a 38-inch John Deere or Lesco mower and your deck requires notched high-lift blades. It’s a good choice for homeowners or light commercial use where OEM cost is a concern. Skip it if you need mulching blades or if your deck uses straight-edge blades.
