Why customers choose Cera Garden

Overview

Replace worn blades with GICOOL GX20249 mulching blades designed for John Deere 42 inch decks. These parts fit older L series round hole mowers and are built to streamline yard maintenance with a consistent mulching action and clean finish.

Why choose GICOOL GX20249

  • Compatibility with John Deere 42 inch decks: L100, L105, L110, L111, L118; Scotts L1742, L17.542; Sabre 108-14.5 and 108-17HS.
  • Two blades per package for straightforward replacement and balanced cutting performance.
  • Constructed from durable 40MnB steel for reliable, precise cutting across varied grass conditions.
  • Rust resistant coating on the cutting edge helps protect during handling and reduces surface wear over time.

Key blade specs

  • Length: 21-7/16 inches (544 mm)
  • Width: 2-1/2 inches (63 mm)
  • Thickness: 5/32 inch (4 mm)
  • Air lift: 1 inch (25 mm)
  • Center hole: round, 11/16 inch (17.2 mm)
  • Blade type: mulching blade

These blades are designed to deliver a smooth mowing experience with consistent cut quality. The mulching geometry helps process clippings into finer material that can return nutrients to the lawn, while the center hole and mounting interface align with round hole configurations typical of older deck designs.

Fit and installation notes: verify your original blade part number or mower model before purchasing to ensure a perfect match. This product replaces OEM numbers GX20249, GX20433, GY20567, M128485 and MT D equivalents 490-110-0029, 490-110-0046. If in doubt, compare your blade’s length, width, thickness, and hole size with the specs listed here.
