(2 Pack) 134149 Mulching Blades for 42" Cut Craftsman, Husqvarna, Poulan Mowers Replaces 422719 532134149 Husqvarna Poulan Pro 42'' Deck Riding Lawn Mower 

What It Is

This is a 2-pack of 42-inch mulching blades designed to replace OEM parts on Craftsman, Husqvarna, and Poulan Pro riding mowers. They chop clippings finer for even lawn feeding, ideal for mulching setups on 42’’ cut decks.

Fitment & Compatibility

Before buying, confirm:

• Deck size: Must be exactly 42 inches (measured cutting width). Not for 46’’ or 54’’ decks.
• Model fit: Fits Craftsman (LT1000/2000/3000 series), Husqvarna (YTH, GTH, LTH models), Poulan (Pro, PP, PR series), and some AYP/Electrolux-built mowers from the 2000s onward.
• OEM cross: Replaces Husqvarna 532134149, Craftsman 422719, Poulan Pro 134149. Aftermarket; not genuine OEM.
• Measurements: Blade length ~21.75’‘, center hole ~1’', diamond-shaped. Check your existing blade for matching hole shape and length before purchase.

Key Things to Know

• Quality: Typically made from heat-treated steel (Boron or similar), but aftermarket steel may dull faster than OEM. Inspect for warping or thin edges on arrival.
• Installation: Easy with basic tools—jack up mower, remove deck belt, unbolt old blades. Torque bolts to 70–90 ft-lbs. Use thread locker if bolts were loose.
• Common gotcha: These are mulching blades only—not for bagging or side-discharge. If you switch between modes, you’ll need a separate set of lift blades.
• Balance: Always balance after install. Even new aftermarket blades can be off; use a blade balancer to avoid vibration and deck damage.

Should You Buy It

If you own a 42-inch Craftsman, Husqvarna, or Poulan Pro rider, primarily mulch, and want a budget-friendly 2-pack for quick replacement, this is a solid choice. Skip it if you need OEM durability for heavy commercial use or plan to bag/ discharge—you’ll want dedicated lift blades instead.
