2PK Oregon 195-005 Mulching Blade for 42" Craftsman 134149 422719 532134149 777134149

What It Is

The 2PK Oregon 195-005 Mulching Blade is a set of two aftermarket blades designed to replace the factory blades on 42-inch Craftsman lawn tractors, optimized for fine mulching that chops clippings into small pieces to return nutrients to the lawn.

Fitment & Compatibility

Before buying, verify your mower deck is exactly 42 inches (measured cutting width). These blades fit specific Craftsman models using OEM part numbers 134149, 422719, 532134149, or 777134149—check your owner’s manual or current blade for these numbers. The blade measures 21 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch offset. They are a direct replacement for OEM blades but not universal—do not assume they fit other 42-inch decks from different brands (e.g., John Deere, Husqvarna). Confirm your spindle pattern matches (typically a 5-point star pattern on Craftsman).

Key Things to Buy

• Quality: Oregon is a reputable aftermarket brand; these blades are heat-treated and hardened for durability, but may not last as long as OEM in rocky or heavy-duty conditions.
• Installation: Straightforward bolt-on job—requires a socket wrench (usually 5/8-inch or 15/16-inch) and a blade removal tool or block of wood to prevent spinning. Torque to 40-50 ft-lbs.
• Common Gotchas: The “mulching” design has a higher lift than standard blades, which can strain the engine on thick, wet grass—only use for mulching, not bagging. Also, check that your deck has mulching plugs or baffles installed; without them, these blades won’t mulch effectively.
• Pairing: Sold as a pair (two blades), so you’ll have a spare or can replace both at once—always replace in sets for balanced cutting.

Should You Buy It

Buy these if you own a 42-inch Craftsman lawn tractor (models listed above) and prioritize fine mulching over bagging or side discharge. They’re a cost-effective alternative to OEM blades, especially if you mow frequently and want to reduce clippings. Skip them if your deck lacks mulching hardware or you need a universal blade for other brands.
