What It Is

This is a high-lift mower blade designed for Husqvarna 61-inch zero-turn mowers. It replaces OEM part 539113312 and is intended for heavy grass, mulching, and improved bagging performance on commercial or large residential properties.

Fitment & Compatibility

Before buying, check the following:

• Deck size: This blade fits only 61-inch cutting decks. Measure your deck width to confirm.
• Model compatibility: Works with Husqvarna MZ 61, MZT61, MZT61, EZ 6124, and CZT61 zero-turn mowers. Also fits select Craftsman and Jonsered models with the same OEM part (539113312).
• OEM vs aftermarket: This is an aftermarket blade that replaces OEM part 539113312 and 510417901. Verify your original blade’s part number matches one of these.
• Measurements: Blade length is 20.5 inches, center hole diameter is typically 1 inch, and thickness is about 0.25 inches. Measure your existing blade to confirm dimensions match.

Key Things to Know

• High lift design: The aggressive lift angle improves grass clipping discharge and bagging, but it requires more engine power and may wear faster in sandy or rocky soil.
• Installation difficulty: Moderate. You’ll need a socket wrench and possibly a torque wrench (recommended torque: 70-90 ft-lbs). Always disconnect the spark plug and battery before working.
• Balance check: Aftermarket blades sometimes need minor balancing. Use a blade balancer before installation to avoid vibration and bearing wear.
• Sharpening: These blades can be sharpened 2-3 times before replacement. Don’t sharpen beyond the hardened edge or you’ll reduce lift performance.

Should You Buy It

Buy this blade if you own a Husqvarna 61-inch zero-turn and need a reliable, high-lift replacement for bagging or tall grass. It’s a solid aftermarket option at a fair price, but avoid it if you mow mostly in dry, dusty conditions—the high lift will kick up debris and wear faster.
