Overview

The 8TEN LawnRAZOR Blade is built for homeowners who want a cleaner lawn finish with finely mulched clippings. Specifically designed for John Deere 42-inch decks, it aligns with the OEM M170642 specification and fits a broad mix of popular models including Z335E, Z335M, Z345M, Z345R, X380, X350, X370, and X354. If your mower uses a 42-inch deck with the M170642 part, this two-pack can be a practical replacement option that keeps your mowing routine straightforward.

Two blades in each package provide value and convenience so you can swap in a fresh blade without delays. The blade is described as Mulch Rolled, which suggests it is shaped to help grass break down into finer pieces as you mow. While performance depends on grass type and conditions, many users notice a consistent cutting edge that can contribute to an even distribution of clippings across the lawn.
