Keycci 581043901 Mulching Mower Blades Compatible with Hu sqvarna YTH224T YT46LS TS246 YTH224TFI TS346 Lawn Tractors, Gator Blades for Hu sqvarna 46 inch Deck, 2 Pack

What It Is

The Keycci 581043901 mulching blades are a set of two “gator-style” blades designed to cut grass into fine clippings that decompose quickly, reducing the need for bagging. They are intended for Hu sqvarna (Husqvarna) lawn tractors with a 46-inch cutting deck.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 46 inches (measured blade tip to tip). These blades are compatible with specific Husqvarna models: YTH224T, YT46LS, TS246, YTH224TFI, and TS346. They replace OEM part number 581043901. Measure your existing blade length (should be ~20.5 inches if original), center hole diameter (typically 1 inch), and spindle hole pattern (usually a 5-point star). Check your owner’s manual or look up your model’s blade part number to avoid mismatch with other deck sizes (e.g., 42-inch or 54-inch).

Key Things to Know

• Gator blades vs. standard mulch blades: These have serrated edges and a “gator” notch for finer clipping shredding, but they may not chop as well in wet or tall grass as dedicated high-lift blades.
• Installation difficulty: Easy if you have a socket wrench and blade removal tool; use a torque wrench to tighten to manufacturer spec (typically 70–90 ft-lbs). Always disconnect the spark plug and battery first.
• Balance check: After installing, spin the blade by hand to ensure it’s balanced. An unbalanced blade causes vibration, excessive wear on spindles, and poor cut quality.
• Deck clearance: Gator blades have a slightly different lift profile; ensure the blade tips don’t hit the deck shell or discharge chute when spinning.

Should You Buy It

If you own one of the listed Husqvarna tractor models with a 46-inch deck and want finer mulching without bagging, this is a solid budget-friendly upgrade. It’s not for heavy-duty commercial use or for those who prefer standard lift blades for bagging—but for residential mulching, it’s a good value at $24.59 for a 2-pack.
