Arnold 22" High Lift Replacement Blade

What It Is

The Arnold 22" High Lift Replacement Blade is a steel cutting blade designed for walk-behind push mowers with a 22-inch cutting deck. Its high-lift profile creates stronger airflow to improve grass clipping discharge into the bag or side chute, making it ideal for tall or damp grass.

Fitment & Compatibility

• Deck size: Only fits mowers with a 22-inch blade (measure from tip to tip). Do not assume it fits a 21-inch or 23-inch deck.
• Brand/model: Compatible with many Craftsman, Husqvarna, Poulan, MTD, and Troy-Bilt mowers, but always verify your OEM part number. Common matches include 742-0413, 742-0438, and 942-0446.
• Measurements: Check blade length (22"), center hole diameter (typically 7/8" or 1"), and arbor shape (round or star). Arnold uses a universal mounting pattern with a 7/8" center hole and 5-point star adapter for most universal fit.
• OEM vs aftermarket: This is an aftermarket blade. It may not match exact OEM blade thickness or balance. If your mower requires a specific OEM blade for warranty or safety, stick with the original.

Key Things to Know

• Installation difficulty: Easy; requires only a socket or wrench to remove the blade bolt. Use a block of wood to lock the blade.
• Balance check: High-lift blades are more prone to vibration if not balanced. Always test balance after installation and sharpen if needed.
• Grass type: Works best with thick or wet grass but can cause more engine strain on low-powered mowers. Avoid on dry, sandy lawns (increases wear).
• Common gotchas: The high lift may throw debris further—ensure side discharge chute is attached. Also, the blade may not fit mowers with a 5/8" arbor hole.

Should You Buy It

Buy the Arnold 22" High Lift Blade if you have a compatible 22-inch mower and need better bagging performance in heavy grass, especially when mulching isn’t an option. It’s a solid aftermarket upgrade for the price, but skip it if your mower has a non-standard arbor or you prefer a mulching blade for fine clippings.
