These 8TEN LawnRAZOR mulching blades are a two-pack replacement designed to fit Husqvarna 46-inch decks with OEM part number 581043901, restoring cutting performance and producing fine clippings for healthier lawns.

If your Husqvarna mower with a 46" deck is delivering ragged cuts or struggling with grass distribution, worn blades are often the cause. The 8TEN LawnRAZOR replacement pair matches the original blade footprint and hole pattern, so installation is straightforward and the blades work with mulching mower setups to reduce clump formation while maintaining deck balance.

Will these blades fit my Husqvarna YTH224T, TS246 or TS346 mower?

Yes — the set is engineered for specific Husqvarna models that use the 581043901 OEM part. The bolt hole, length and thickness match standard 46" mower decks, allowing a direct replacement without modification.

• Compatible with OEM part number Husqvarna 581043901.
• Fits YTH224T and YTH224TFI model variations with 46" decks.
• Works on TS246 and TS346 models listed in the product details.

How do these blades improve mulching and cut quality?

The LawnRAZOR profile is shaped to lift grass into the mower’s cutting path and then recirculate clippings for finer mulching. That reduces visible clumps on the lawn and returns organic material to the turf surface, which can help with decomposition and appearance.

• Precision-cut edge for consistent blade action across the deck.
• Mulching geometry promotes repeated chopping of clippings.
• Balanced design minimizes vibration and uneven wear.

What are the physical specifications and material details?

Each blade in the two-pack measures approximately 22 7/8" in length, 2 1/4" in width, and 0.157" thick, with a center hole of 4/5" to match the spindle hardware. The dimensions mirror the OEM shape so you retain factory clearance and rotation characteristics.

• Length: 22 7/8"; Width: 2 1/4"; Thickness: 0.157".
• Center hole diameter: 4/5" for direct fit to compatible Husqvarna spindles.
• Two blades included to service both sides of the 46" deck as needed.

How do I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect spark plug, raise mower, remove blade fasteners, swap blades keeping correct orientation, and torque bolts to manufacturer specs. Regular sharpening and periodic balancing will extend blade life and maintain cut quality.

• Always disconnect spark plug before working under the deck.
• Keep blade leading edges sharp and check balance after sharpening.
• Inspect mounting hardware and replace worn bolts or washers.
