JYLEYJ Mulching Blades for 48" Riding Mower – 3-Pack, 16 5/8" OEM-Style 5-Point Fit

These JYLEYJ mulching blades are a 3-pack of direct-fit, heavy-duty replacement blades designed for 48-inch Husqvarna, Craftsman and Poulan riding mower decks to restore cutting performance and improve mulching.

If your 48" mower deck is leaving uneven clippings, clogging, or failing to mulch, replacing worn blades with properly sized, balanced mulching blades can make a noticeable difference. The JYLEYJ 173921 set replaces several OEM part numbers and fits a wide range of Husqvarna YTH and GTH models, plus compatible Craftsman and Poulan Pro machines. Each blade is manufactured to the OEM-style 5-point star center and delivers the dimensions needed for a true replacement: 16 5/8" length, 2 1/2" width, and 0.203" thickness.

How will these blades change my mowing results?

Swapping in mulching blades tuned to your deck geometry improves the lift and recut action that reduces clump formation and returns finer clippings to the lawn. You’ll get a cleaner-looking cut and fewer stops to unclog the deck.

• Finer mulching action for faster decomposition of clippings
• Reduced deck clogging and more consistent discharge
• Even cutting profile that restores original deck performance
