Husqvarna 954636867 42-Inch Lawn Mower Mulching 2 Blade Kit For LT18542, LTH18542, LTH2042 and YTH1542XP,Orange

What It Is

This is an OEM Husqvarna 2-blade mulching kit designed specifically for 42-inch cutting decks. The blades are optimized to chop clippings finely and recirculate them into the lawn, eliminating the need for bagging on compatible Husqvarna models.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size. This kit fits Husqvarna LT18542, LTH18542, LTH2042, and YTH1542XP models—all with a 42-inch deck. Measure your existing blade length: these blades are 20.5 inches long, 2.25 inches wide, with a 1-inch center hole and a 0.5-inch offset. The part number is OEM Husqvarna 954636867. Do not assume fitment for other brands (e.g., Craftsman, Poulan) unless you cross-reference the blade dimensions and center hole pattern. Check your owner’s manual or current blade part number to confirm.

Key Things to Know

• Quality: OEM Husqvarna blades are heat-treated and balanced from the factory. They typically last 25–50 hours of mowing, depending on debris and grass conditions.
• Installation: Requires a socket or wrench (usually 5/8-inch or 15/16-inch) and a blade removal tool or block of wood to prevent rotation. Torque to 70–90 ft-lbs. No special skills needed, but always disconnect the spark plug first.
• Common gotcha: These are mulching blades, not standard lift blades. They produce a finer cut but may not bag or side-discharge as effectively. If you switch between mulching and bagging, you’ll need to swap the entire blade set.
• Balance check: Even though OEM blades are pre-balanced, it’s good practice to check balance after sharpening. An unbalanced blade causes vibration and bearing wear.

Should You Buy It

If you own one of the listed Husqvarna 42-inch models and prefer a clean, clippings-recycled lawn without bagging, this kit is a direct, reliable upgrade from standard blades. It’s not for side-discharge or heavy bagging use. For the price and OEM fit, it’s a solid choice for homeowners who mulch regularly.
