Husqvarna 586918102 Lawn Tractor 42-in Deck Bagging Blade (Replaces 586918101) Genuine Original Equipment Manufacturer (OEM) Part

What It Is

This is a genuine Husqvarna OEM bagging blade designed for 42-inch lawn tractor decks, optimized for collecting clippings into a bagger system rather than mulching or side-discharging.

Fitment & Compatibility

• Deck size: Fits only 42-inch (107 cm) Husqvarna mower decks. Measure your deck width before ordering.
• Model compatibility: Replaces part 586918101. Fits Husqvarna YTH22V46, TS142, and similar 42-inch deck tractors from the 2010s onward. Check your owner’s manual or existing blade part number.
• OEM vs aftermarket: This is a genuine Husqvarna part, not a universal or aftermarket blade. Aftermarket blades may differ in thickness, hole size, or balance.
• Measurements: Blade length is approximately 21 inches, with a 1-inch center hole and a 0.5-inch offset for bagging lift. Verify your blade’s measurements before install.

Key Things to Know

• Bagging performance: The blade has a higher lift angle than standard or mulching blades, which improves airflow into the bagger but reduces mulching quality.
• Installation difficulty: Easy for DIYers—just a socket wrench and jack stands. Torque to 70-90 ft-lbs. Use thread locker if reinstalling on a worn spindle.
• Sharpness: OEM blades come sharp but not razor-edged. They dull faster in sandy or wet grass. Sharpen or replace every 25 hours of use.
• Common gotcha: Do not use on decks with a mulch plug installed—the blade will clog and vibrate. Only use with the bagger attachment.

Should You Buy It

If you have a Husqvarna 42-inch deck and use a bagger regularly, this is the correct, reliable OEM blade for maximum lift and collection efficiency. It’s not for mulching or side-discharge—stick with it for bagging only.
