Hipa 3-Pack 532180054 Mulching Mower Blades 5-Point Star Set for Husqvarna Z248F YTH24V48 YTH24K48 48 inch Riding Mower Lawn Mower Models Replace 180054 173920 Blade

What It Is

This is a 3-pack of mulching mower blades designed for 48-inch riding mower decks, specifically Husqvarna Z248F, YTH24V48, and YTH24K48 models. They use a 5-point star center hole design to improve grass mulching by creating more lift and finer clippings.

Fitment & Compatibility

• Deck size: Only for 48-inch cutting decks—do not use on 42-inch or 54-inch decks.
• Model check: Direct fit for Husqvarna Z248F, YTH24V48, YTH24K48. Also fits select Craftsman, Poulan, and McCulloch models using OEM blade numbers 180054 or 173920.
• Measurements: Each blade is approximately 16.5 inches long, 2.5 inches wide, with a 5-point star center hole (1-inch diameter). Verify your current blade length and center hole shape before ordering—standard round center holes will not fit.
• OEM vs aftermarket: This is an aftermarket set, not genuine Husqvarna. Quality is acceptable for the price, but expect slightly thinner steel than OEM.

Key Things to Know

• Installation: Easy DIY job with a socket wrench and torque wrench (recommended 70-90 ft-lbs). Use thread locker if bolts are reused.
• Balance: Out of the box, these blades are usually balanced well, but always check with a blade balancer before mounting to avoid vibration.
• Sharpness: They come sharp enough for initial use but will dull faster than premium OEM blades—plan to sharpen after 10-15 hours of mowing.
• Mulching performance: The 5-point star design improves fine chopping, but on wet or tall grass, you may need to overlap passes to avoid clumping.

Should You Buy It

Buy this if you have a 48-inch Husqvarna riding mower (Z248F, YTH24V48, or YTH24K48) and want an affordable mulching blade set that works well for regular residential lawn care. Skip it if you need maximum durability for heavy commercial use or if your mower uses standard round-center blades.
