Husqvarna Blade, 19" Gator, 1.25" Lift Part # 525525901

What It Is

The Husqvarna Blade, 19" Gator, 1.25" Lift (Part # 525525901) is a high-lift mulching and bagging blade designed to improve grass clipping discharge and cutting performance on select Husqvarna and compatible lawn tractors. It’s best for residential mowing with medium-to-heavy grass conditions.

Fitment & Compatibility

• Deck size: This blade fits 19-inch cutting decks only. Measure your deck width and blade length precisely—do not assume it matches a 20-inch or 18-inch deck.
• Model/brand fit: Designed for Husqvarna models like YTH1542XP, YTH18542, TS142, and LGT2654, but also fits many Craftsman, Poulan, and McCulloch tractors using the same spindle pattern. Check your deck’s blade bolt pattern (center hole and offset) against OEM specs.
• OEM vs aftermarket: This is a genuine Husqvarna part, not an aftermarket knock-off. It’s a direct replacement for OEM blades on compatible decks.
• Measurements: Blade length is 19 inches, center hole diameter is typically 1 inch, and the lift height is 1.25 inches. Verify your current blade’s length, center hole, and lift before purchasing.

Key Things to Know

• Quality: The Gator design uses a notched, serrated edge to shred clippings finer, reducing clumping and improving mulching. It’s made from hardened steel for durability.
• Installation difficulty: Easy—requires a socket wrench to remove the blade bolt (usually 5/8-inch or 13/16-inch). Use a block of wood to jam the blade when loosening. Always torque the bolt to 40-50 ft-lbs.
• Common gotcha: This blade has a 1.25-inch lift, which is higher than standard lift blades. It works well for bagging and mulching but may cause uneven cut or scalping on uneven terrain—adjust deck height accordingly.
• Sharpening: Do not sharpen the serrated edge; replace when dull. The Gator pattern is designed to be disposable.

Should You Buy It

Buy this blade if you have a compatible 19-inch Husqvarna deck and want better mulching or bagging performance than standard blades. It’s a direct OEM upgrade that’s worth the price for finer clippings and less cleanup, but avoid it if your lawn has steep hills or rough ground where the high lift could scalp.
