Greenworks Replacement Blade (42' Tractor and Zero Turn) 1 Blade Included

What It Is

This is a genuine Greenworks replacement blade designed for 42-inch cutting decks on Greenworks tractors and zero-turn mowers. It is intended for users needing a single blade replacement for a worn or damaged OEM blade.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch deck and is a Greenworks model (e.g., 24202, 24252, or similar zero-turn/tractor series). This is an OEM part, not an aftermarket universal blade. Check the blade’s exact length (likely around 20–21 inches), center hole size, and thickness against your current blade—Greenworks blades often have a specific star or diamond-shaped center hole. If your mower uses a three-blade spindle setup, note that this listing includes only one blade; you’ll need to buy three for a full replacement. Not compatible with other brands (e.g., Husqvarna, John Deere) without confirmation of identical specs.

Key Things to Know

• Quality: OEM-grade steel with a durable coating to resist rust and dulling, but not as thick as some heavy-duty aftermarket blades.
• Installation: Straightforward with basic tools (socket wrench and blade removal tool). Torque spindle bolts to manufacturer specs (typically 70–90 ft-lbs) to avoid loosening.
• Gotchas: This is a single blade—check your deck’s blade count. If you have a three-blade 42-inch deck, you’ll need to buy three units. Also, ensure your mower uses a single-blade pattern; some 42-inch decks use two blades.
• Sharpness: Comes sharp enough for initial use but may need sharpening after a few mows on tough grass or debris.

Should You Buy It

If you own a Greenworks 42-inch tractor or zero-turn mower and need a direct OEM replacement for a single damaged blade, this is a reliable, hassle-free choice. It’s ideal for users who prefer exact fit over aftermarket alternatives and want to avoid compatibility guesswork. However, if you need a full set or a heavier-duty blade for rough terrain, consider aftermarket options or buy multiple units.
