Husqvarna 532180054 Hi Lift Blades, Pack of 3

What It Is

The Husqvarna 532180054 Hi Lift Blades (pack of 3) are OEM replacement blades designed for 42-inch cutting decks on Husqvarna and compatible lawn tractors. Their high-lift profile increases airflow for superior grass clipping discharge and bagging performance, making them ideal for tall or wet grass conditions.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This set fits 42-inch (107 cm) cutting decks only. Measure your deck width if unsure.
• Model compatibility: Direct OEM fit for Husqvarna models like YTH22V46, TS242XD, and GTH52XLSI. Also fits some Craftsman, Poulan Pro, and AYP (American Yard Products) tractors with 42-inch decks. Check your owner’s manual or current blade part number.
• Measurements: Each blade is 21 inches long, 2.5 inches wide, with a 7-point star center hole and 0.25-inch thickness. Confirm these dimensions match your existing blade—especially the center hole shape (star vs. oval/diamond) and blade length. Not for zero-turn mowers or 46/48/54-inch decks.

Key Things to Know

• Installation: Moderate difficulty—requires a socket wrench, torque wrench (set to 50-70 ft-lbs), and safety blocks. Lift the deck or mower safely, and always replace all three blades as a set for balanced cutting.
• Quality: OEM Husqvarna steel holds an edge well but is not hardened for rocky yards. Expect to sharpen or replace every 25-50 hours of use.
• Common gotcha: Hi-lift blades create more lift and noise than standard blades. They can throw debris further—always use the discharge chute and wear eye protection.
• Balance: After installation, check blade balance (use a balancer or nail in a wall). An unbalanced blade causes vibration and deck damage.

Should You Buy It

Buy this set if you own a Husqvarna or compatible 42-inch tractor, mow tall or damp grass, and want better bagging or side-discharge performance. Skip it if you have a smaller deck, prefer standard lift blades for mulching, or mow rocky terrain—the higher lift increases risk of blade damage from impacts.
