GELASKA 405380 Mower Blades for Husqvarna 46 Inch YTH22V46 Z246 Z246i YTH20K46 YTH21K46 RZ4619 RZ4620 RZ4621 RZ4622 RZ4623 RZ46i Mower Decks, Replaces 532405380 532403107 594892801, 2 Pack High Lift

What It Is

This is a 2-pack of high-lift replacement blades designed for 46-inch Husqvarna mower decks. High-lift blades create increased airflow for superior grass clipping discharge, making them ideal for bagging or side-discharge in tall or thick grass.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck (not 42 or 54 inch). These blades fit specific Husqvarna models: YTH22V46, YTH20K46, YTH21K46, Z246, Z246i, RZ4619, RZ4620, RZ4621, RZ4622, RZ4623, and RZ46i. They replace OEM part numbers 532405380, 532403107, and 594892801.

Measure your existing blade length: these are 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset. If your original blade has a different center hole size or offset, it won’t fit. Verify the spindle pattern matches (usually 5-point star or oval). Aftermarket blades may require rebalancing—check blade balance before installation.

Key Things to Know

• Quality: Made from heat-treated steel, but some users report they dull faster than OEM Husqvarna blades in sandy or rocky soil. Inspect after every 10 hours of use.
• Installation: Easy swap with a socket wrench. Always use a blade removal tool or block the blade to prevent rotation. Torque bolts to 70-90 ft-lbs.
• Gotchas: High-lift blades increase engine load and may cause vibration if not balanced. They also produce more noise than standard blades. If you mostly mulch, low-lift blades are better.
• Compatibility check: Double-check your deck’s spindle bolt size—these use a 5/8-inch center hole. Some newer Husqvarna decks require a 7/8-inch hole.

Should You Buy It

If you own one of the listed Husqvarna 46-inch models and primarily bag or side-discharge grass, these are a solid, affordable alternative to OEM blades. They’re not for mulching or heavy-duty commercial use, but for residential lawns they deliver good lift and cut quality at half the OEM price. For mulching or rocky terrain, look for standard or low-lift blades instead.
