Hipa 2-Pack 138971 High Lift Mower Blades 5-Point Star Set for Craftsman LT1000 LT2000 42 inch Riding Mower, Husqvarna 42'' Deck Lawn Tractor Models Replace for 532138971 422719 42 Inch Blades

What It Is

This is a 2-pack of high-lift, 5-point star replacement blades for 42-inch cutting decks, designed for Craftsman LT1000/LT2000 series and Husqvarna riding mowers. High-lift blades create stronger airflow to improve bagging and leaf mulching compared to standard blades.

Fitment & Compatibility

• Deck size: 42 inches only. Measure your deck width (blade tip to tip) before ordering.
• Fitment: Compatible with Craftsman LT1000, LT2000, and many Husqvarna 42-inch deck models. Also fits some Poulan, AYP, and Murray tractors with the same spindle pattern.
• OEM reference: Replaces OEM part numbers 532138971, 422719, 138971, and 532416296.
• Measurements: Blade length 20.5 inches, center hole 5/8 inch, with a 5-point star pattern. Verify your spindle has a star-shaped mounting hole (not round or oval).
• Not compatible with 46-inch or 54-inch decks, or zero-turn mowers.

Key Things to Know

• Installation difficulty: Easy to moderate. Requires a socket wrench and torque to 70-90 ft-lbs. Use a blade removal tool or block wood to prevent spinning.
• High-lift trade-off: Better bagging and lift, but more engine load and slightly reduced fuel efficiency. Not ideal for dry, dusty conditions.
• Balance check: Aftermarket blades sometimes need balancing. Use a blade balancer (under $10) to avoid vibration and spindle wear.
• Common gotcha: The 5-point star pattern is less common than standard 2-point or oval holes. Confirm your spindle matches before buying.

Should You Buy It

Yes, if you own a Craftsman LT1000/LT2000 or compatible Husqvarna with a 42-inch deck and need reliable high-lift blades for bagging or heavy leaf mulching. The price is fair, and the 4.7-star rating reflects solid build quality. Avoid if your spindle uses a different mounting pattern or if you primarily side-discharge on dry lawns.
