Designed for 54-inch mower decks, these blades fit John Deere models such as G110, 190C, LA150, LA175, D170, E180, and S180. The Craftsman reference SPM684375001 is also included in the compatibility notes, expanding the potential matches for your machine.

Design and performance

The medium lift blades are tailored for thicker grass, helping blades maintain balance while delivering a consistent cut across the reel. The edge is sharp once the protective coating wears away after first use, signaling readiness for mowing. The blades are painted for safety in shipping and handling; wear off the paint reveals the actual cutting edge when you start mowing.

• Medium lift design optimizes lift for thicker turf
• Sharp, dependable edge for consistent cuts
• Durable construction helps maintain balance during use

Installation and notes

Replacing dull or bent blades is a quick process with common tools. Ensure the cutting edges face toward the ground during installation and use a torque wrench if available. The painted surface acts as a safety hint and will peel back to reveal the sharp edge after the first use.

• Easy swap in just a few minutes with standard tools
• Edge-down orientation ensures proper operation
