403107 532403107 Lawn Mower Blade Gator for Husqvarna 46 inch YTH22V46 Z246 RZ4623 YTA22V46 YTH21K46 Craftsman AYP Zero Turn Riding Mower, High Lift 5-Star Mulching Mower Blade, 2 Pack

What It Is

This is a 2-pack of 46-inch high-lift, 5-star mulching blades designed for Husqvarna, Craftsman, and AYP zero-turn and riding mowers. The 403107/532403107 blades improve grass lift and mulching performance compared to standard OEM blades.

Fitment & Compatibility

Before buying, measure your existing blade—these are 18.5 inches long, 2.5 inches wide, with a 1-inch diameter center hole and a 0.5-inch offset. They fit Husqvarna YTH22V46, Z246, RZ4623, YTA22V46, YTH21K46, and Craftsman/AYP models with a 46-inch deck. Verify your mower’s deck size and blade mounting pattern; these are aftermarket replacements for OEM part numbers 403107, 532403107, and 173969. They do not fit 42-inch or 54-inch decks.

Key Things to Know

• High-Lift Design: The curved tips increase airflow, improving bagging and side-discharge, but may cause more wear on the blade spindle and deck if used on very thick, wet grass.
• Mulching Performance: The 5-star shape chops clippings finer than standard blades, reducing the need for bagging. Not ideal for mowing tall, damp grass—clumps can form.
• Installation: Use a torque wrench to tighten the blade bolt to 70-90 ft-lbs. The blades are sharp out of the box; handle with gloves. Balance the set before mounting to avoid vibration.
• Durability: Made from heat-treated steel, but aftermarket blades may not last as long as OEM in rocky or sandy soil. Inspect for bends after each season.

Should You Buy It

Buy these if you own a 46-inch Husqvarna or Craftsman zero-turn or riding mower and want better mulching or bagging performance without paying OEM prices. Skip them if you need a standard lift blade for flat, dry lawns or have a different deck size.
