Terre Products, 2 Pack Mulching Lawn Mower Blades, 42 Inch Deck, Compatible with Craftsman, Husqvarna, Poulan, Replacement for 134149, 138971, 138498, 127843, 532138971, 532138498, PP24003

What It Is

This is a 2-pack of mulching blades designed for 42-inch cutting decks. They are a direct replacement for OEM parts on Craftsman, Husqvarna, and Poulan riding mowers, intended to chop clippings finely for nutrient recycling.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 42 inches—measure from blade tip to blade tip. These blades replace OEM part numbers 134149, 138971, 138498, 127843, 532138971, 532138498, and PP24003. They are aftermarket, not OEM, so check that your mower’s spindle hole pattern matches (usually a 5-point star or 4-point). Verify blade length (approx. 21.5 inches) and center hole diameter (typically 1 inch) against your current blade. Not for zero-turn or walk-behind mowers unless specified.

Key Things to Know

• Build quality: Made from heat-treated steel; users report they are slightly thinner than OEM but hold an edge well.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool. Torque to 70-90 ft-lbs; use thread locker if bolts are loose.
• Gotchas: Mulching blades require a mulching kit or plugged discharge chute to work properly. They may not fit decks with unusual spindle offsets—measure twice.
• Pack size: Two blades cover one 42-inch deck (two blades per mower). No extras.

Should You Buy It

Buy this if you own a 42-inch Craftsman, Husqvarna, or Poulan riding mower and want an affordable aftermarket mulching upgrade. It’s a solid value for fine mulching performance, but skip if you need OEM precision or have a non-standard deck.
