8TEN Spindle Medium-Lift Blade for Husqvarna 46 Inch Deck Z246 Z246i RZ 4621 4622T 4623 46i Zero Turn Mower 532174356

What It Is

This is a medium-lift replacement blade set for 46-inch cutting decks on select Husqvarna zero-turn mowers. Designed for mulching or bagging grass clippings, it balances lift and cutting efficiency for residential use.

Fitment & Compatibility

• Deck size: 46 inches. Measure your deck width before ordering—this set fits only 46-inch models.
• Specific models: Husqvarna Z246, Z246i, RZ4621, RZ4622T, RZ4623, and 46i zero-turn mowers. Verify your model number on the chassis tag.
• OEM part number: Replaces Husqvarna 532174356. Check your owner’s manual or current blade for this number.
• Measurements: Blade length is approximately 18.25 inches; center hole diameter is 0.625 inch (5/8 inch). Confirm these match your spindle holes.
• Quantity: Sold as a set of three blades (one per spindle). Do not mix with other blade types on the same deck.

Key Things to Know

• Quality: Medium-lift design—good for everyday grass, not ideal for heavy wet grass or deep leaf mulching. Blade thickness and steel grade are comparable to OEM.
• Installation: Straightforward if you have a socket set (typically 15/16 inch for spindle bolts). Torque bolts to 70–90 ft-lbs; use thread locker if bolts are loose.
• Common gotchas: These blades are stamped, not forged—bend more easily on rocks or stumps. Check balance before installing; if one is off, return the set.
• Sharpening: Edge holds reasonable sharpness for 2–3 mowings on dry grass. Sharpen with a file or grinder; avoid grinding the medium-lift curve flat.

Should You Buy It

If you own a compatible Husqvarna 46-inch zero-turn and need a reliable, direct-fit replacement for mulching or bagging, this is a solid choice. Avoid it if you mow rough terrain, want high-lift blades for wet grass, or need a heavy-duty forged blade.
