Lawn Mower Blades for 46" Deck, Compatible with Hu-sqvarna Craftsman Pou LAN, Replaces 145708, 157033, 152443, 163819, 532145708, 532152443, 532163819, 3 Pack

What It Is

These are replacement 3-blade sets for 46-inch cutting decks, designed for residential riding mowers. They fit Husqvarna, Craftsman, Poulan, and other brands using the same spindle pattern, ideal for medium-duty grass cutting on lawns up to a few acres.

Fitment & Compatibility

Before buying, confirm all three of these:

• Deck size: Your mower must have a 46-inch cutting deck (measure blade tip to tip or check your model specs).
• Blade dimensions: Each blade is 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and 5-point star drive. Measure your old blade’s length, width, and hole shape.
• OEM cross-reference: These replace OEM numbers 145708, 157033, 152443, 163819, 532145708, 532152443, and 532163819. Check your mower’s manual or existing blade part number.
• Brand compatibility: Works on most Husqvarna, Craftsman (non-42-inch), Poulan, and some AYP/Electrolux models with 46-inch decks. Avoid if your deck uses a different spindle pattern (e.g., 42-inch or 54-inch).

Key Things to Know

• Quality: Aftermarket blades, typically 3/16-inch thick steel with a coated finish. Acceptable for residential use, but may dull faster than OEM or premium high-lift blades.
• Installation: Easy with basic hand tools (socket wrench, torque wrench). Use a blade removal tool or wedge to prevent spinning. Torque bolts to 35-45 ft-lbs. Always replace all three blades at once for balanced cutting.
• Common gotchas: The star drive hole can be tight on some spindles—file lightly if needed. Don’t assume “universal” fit; verify your spindle type (star vs. diamond vs. round). Check blade orientation (air lift side up) before tightening.
• Maintenance: Sharpen after 10-15 hours of use. Inspect for cracks or bends after hitting rocks or stumps.

Should You Buy It

If you need a budget-friendly 3-pack for a 46-inch Husqvarna, Craftsman, or Poulan rider and you’re okay with aftermarket steel that performs adequately for regular grass cutting, this is a solid value. Skip it if you need premium durability for tough, tall, or wet grass—spend more on OEM or high-lift blades instead.
