Mr Mower Parts 42" Mower Mulching Blades 2 Pack Compatible with Craftsman Husqvarna Poulan 134149 532134149 594892701

What It Is

This is a 2-pack of 42-inch mulching blades designed for residential riding mowers. They replace OEM part numbers 134149, 532134149, and 594892701, and are meant to cut grass into fine clippings that decompose quickly, eliminating the need to bag.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck and uses blades with a 1-inch center hole, 3/4-inch diameter arbor hole, and 5/8-inch offset. These blades are compatible with many Craftsman, Husqvarna, and Poulan models (including some from the 2000s and 2010s), but also fit certain AYP, Murray, and Sears units. Check your mower’s model number against the compatibility list provided by Mr Mower Parts. Do not assume all 42-inch decks use the same blade—measure your existing blade’s length, center hole diameter, and offset before ordering.

Key Things to Know

• Quality: Made from heat-treated steel, these blades are durable but may not hold an edge as long as OEM or premium brands like Oregon. Expect to sharpen or replace them every season with heavy use.
• Installation: Easy for anyone with basic tools—requires a socket wrench and a block of wood to lock the blade. Torque the center bolt to 70–90 ft-lbs; under-tightening can cause blade throw.
• Common gotcha: Mulching blades have a higher lift profile than standard blades, so they work best when mowing dry grass at a slower ground speed. Wet or tall grass will clog the deck.
• Balance: Blades come pre-balanced, but double-check with a blade balancer before installing to avoid vibration that can damage spindle bearings.

Should You Buy It

If you have a 42-inch Craftsman, Husqvarna, or similar riding mower and want an affordable, no-fuss mulching blade set for regular lawn maintenance, this 2-pack is a solid value. It’s not the best for commercial use or tough conditions, but for homeowners who mow weekly and want fine clippings, it’s a reliable choice that matches OEM specs.
