(2) High Lift Mower Blades Fits Craftsman Riding Mowers 46" Deck Replaces 532405380

What It Is

This is a set of two high-lift mower blades designed for Craftsman riding mowers with a 46-inch cutting deck. High-lift blades create stronger airflow to lift grass for a cleaner cut and better bagging performance, making them ideal for mulching or collecting clippings in tall or thick grass.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck (measure deck width between blade tips). These blades replace OEM part number 532405380 (also cross-referenced as 405380). They fit most Craftsman, Husqvarna, and Poulan Pro riding mowers with a 46-inch stamped or fabricated deck, including models like 917.xxxxx series. Check your mower’s model number (under seat or on frame) against the manufacturer’s parts list—these blades are often used on LT2000, LT3000, and GT5000 series. Note: high-lift blades may not fit decks with low clearance (e.g., some older Craftsman decks designed for low-lift blades). Measure blade length: these are typically 20.5 inches center hole to tip. Verify your spindle hole is 1-inch round (most common) and the blade thickness is 0.25 inches. Aftermarket blades may vary slightly in balance—weigh them before installation.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and torque to 40-50 ft-lbs. Use thread locker on spindle bolts to prevent loosening.
• Common gotcha: High-lift blades draw more power and may bog down the engine in thick grass. Use at full throttle and avoid cutting wet, heavy growth to prevent stalling.
• Quality note: These are aftermarket replacements, not OEM Craftsman. Some users report slightly thinner steel or uneven balance—check with a blade balancer before mounting.
• Performance: Excellent for bagging and mulching, but can throw debris. Wear eye protection and keep bystanders clear.

Should You Buy It

If you need to replace worn or damaged blades on your 46-inch Craftsman rider and want improved bagging or mulching performance, this is a solid budget-friendly option. However, if your mower has a low-clearance deck or you primarily cut dry, short grass, consider low-lift blades instead to reduce engine strain.
