8TEN LawnRAZOR High-Lift Replacement Blades for Husqvarna 61" Deck - 3 Pack, 21" Durable Steel

8TEN LawnRAZOR high-lift replacement blades are heavy-duty 21" cutting blades engineered to fit Husqvarna 61" deck mowers, delivering improved lift and consistent clippings discharge.

If your zero-turn or garden tractor uses a 61-inch cutting deck and needs replacement blades that match OEM fit and performance, this 3-pack of 8TEN LawnRAZOR blades is built to be a direct, durable alternative to part number 539113312. Each blade is formed for high-lift airflow to help collect, mulch, or side-discharge grass efficiently, and they’re sized to the same dimensions used by many Husqvarna MZ, EZ, and CZT models.

What machines are these 8TEN blades compatible with?

These blades fit a range of Husqvarna, AYP, Craftsman, Jonsered and RedMax decks that use the 5-point star center and a 21" length for 61" cutting decks.

• Directly compatible with Husqvarna EZ 6124, EZ 6124 KOA, FD61M, MZ 61, MZ 6125, MZ 6125 C, MZ 6128, and MZT61 models.
• Works with OEM part 539113312 and equivalent AYP/Craftsman/Jonsered items.
• Also fits RedMax models such as CZT60L, CZT61, and RZT61x that share the same mounting pattern.

How do these high-lift blades affect cutting and debris handling?

High-lift blades are shaped to pull grass upward into the deck’s airflow, improving lift for a cleaner, more even cut and better discharge to a bagger or side chute. They’re especially useful when you want tidy clipping evacuation or improved mulch circulation in thicker turf.

• Rolled-tip high-lift profile increases upward suction for cleaner cuts and effective bagging.
• Helps reduce clumping by accelerating clippings into the deck discharge system.
• Maintains a consistent cut height when blades are balanced and sharp.

What are the precise blade dimensions and mounting details?

Knowing the exact size and hole pattern ensures the blade will mount securely and operate safely on your 61" deck. These 8TEN blades match the common factory measurements for this group of mowers.

• Overall length: 21.00 inches; blade cutting width: 2.5 inches; thickness: 0.197 inches.
• Center mount: 5-point star (5/8" or approximately 0.63") compatible with the specified Husqvarna hub pattern.
• Type: high-lift rolled-tip design for strong upward airflow and reliable clipping ejection.

How should I install and maintain these replacement blades?

Installation requires matching the 5-point star center to your spindle and torquing the blade nut to the mower manufacturer’s specification. Regular maintenance will keep cut quality high and extend blade life.

• Always install blades with the cutting edge facing the direction of rotation and use correct torque values from your mower manual.
• Inspect for nicks, bends, or excessive wear; sharpen evenly and rebalance after grinding.
• Replace blades in matched sets (this 3-pack covers most three-blade 61" decks) for consistent performance.

Who is this for? Lawn care professionals and homeowners with 61-inch Husqvarna-compatible decks who want a reliable, OEM-matching blade solution will benefit from this 3-pack. It’s aimed at users who need a high-lift profile for cleaner bagging or side discharge, want exact-fit mounting to a 5-point star hub, and prefer buying blades in matched sets to preserve even cutting across wide decks.
