Husqvarna 42-Inch Mulching Lawn Mower Blades, Lawn Mower Parts Riding Mowers, Replacement for OEM Part No. 594892701, Orange, Pack of 2

What It Is

This is a set of two 42-inch mulching blades designed for Husqvarna riding mowers. They replace OEM part number 594892701 and are meant to finely chop grass clippings for nutrient recycling, reducing the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck—this is non-negotiable. These blades are direct OEM replacements for Husqvarna models like the YTH22V46, TS142, and GTH52, but also fit some Craftsman, Poulan, and McCulloch units with the same deck size. Measure your current blade’s length (center hole to tip) and thickness (typically 0.25 inches). Verify the center hole diameter (usually 1 inch) and the number of mounting holes (most use a single center hole with a star pattern). If your deck uses a different spindle or blade pattern (e.g., oval or offset holes), these won’t fit. Check your owner’s manual or look up your mower’s model number on Husqvarna’s site for explicit compatibility.

Key Things to Know

• Mulching vs. regular blades: These have a curved, serrated edge to create a vacuum that recuts clippings. They won’t discharge or bag well—use only for mulching.
• Installation difficulty: Easy if you have a socket wrench and a block of wood to jam the blade. Torque the center bolt to 70–90 ft-lbs; overtightening can strip the spindle.
• Sharpness out of box: They come sharp but not razor-edged. Expect a break-in period of 1–2 mows for best mulching performance.
• Balance check: Always balance new blades before mounting (use a balancer or nail in a wall). An unbalanced blade vibrates and damages the spindle.

Should You Buy It

Buy these if you own a Husqvarna or compatible riding mower with a 42-inch deck and want clean, fine mulching without switching blades. They’re a solid OEM-quality choice at a fair price, but verify your deck size and blade hole pattern first to avoid a return.
