173920 High Lift Blades for 48" Deck, 532180054 Mower Blades Compatible with Hus-qvarna YTH24V48 YTH2348, Pou LAN PP22V48, Craftsman Lawn Tractor, Replaces 180054 539107519 PP24005, 3 Pack

What It Is

This 3-pack of high-lift blades is designed for 48-inch cutting decks, optimized for bagging and side-discharge on Husqvarna, Poulan, and Craftsman lawn tractors. The curved blade design increases airflow to lift grass clippings more aggressively than standard blades.

Fitment & Compatibility

Check deck size first – these fit only 48-inch decks, not 42-inch or 54-inch. Compatible models include Husqvarna YTH24V48, YTH2348, Poulan PP22V48, and Craftsman lawn tractors with a 48-inch deck. Replaces OEM part numbers 180054, 532180054, 539107519, and PP24005. Measure your current blade – these are 20.5 inches long, 2.5 inches wide, with a 7/16-inch center hole and 1-inch diameter hub. If your blade has a different hole size or offset, they won’t fit. Always verify your deck’s spindle pattern (center hole + two small mounting holes) matches before ordering.

Key Things to Know

• High-lift = more power draw – these blades create extra suction, so they can strain smaller engines (under 18 HP) on thick or wet grass. You may need to slow your ground speed.
• Installation tip – use a blade removal tool and torque to 40-50 ft-lbs. Hand-tightening risks blade coming loose. Always lift the deck and disconnect the spark plug.
• Balance check – after installing, spin each blade by hand. A wobble means unbalanced blades, which can damage the spindle or deck. If needed, have them balanced at a shop.
• Not for mulching – high-lift blades are poor at mulching. If you want fine clippings left on the lawn, buy dedicated mulching blades instead.

Should You Buy It

If you bag grass or side-discharge on a 48-inch deck tractor (Husqvarna, Poulan, or Craftsman), and your engine has adequate power, this is a solid, affordable upgrade over stock blades. Avoid if you primarily mulch or have a smaller engine.
