What It Is

These are mulching blades for 38-inch deck mowers, designed to cut grass into fine clippings that decompose quickly as natural fertilizer. They replace OEM part numbers for AYP, Poulan, Craftsman, and Husqvarna riding mowers.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be exactly 38 inches. Measure your deck width—this 2-pack fits only 38-inch decks.
• OEM cross-reference: Confirmed fits AYP 12784, 127842, 134148; Poulan 134148, 138497, 532127842; Craftsman 127842, 134148, 138497; Husqvarna 532127842, 532134148, 532138497. Check your current blade’s part number against this list.
• Measurements: Each blade is roughly 19 inches long, 2.5 inches wide, with a 1-inch center hole and 7-point star center. Measure your old blade’s length, width, and center hole shape.
• Aftermarket note: OCPTY is an aftermarket brand, not OEM. Quality is generally good, but fitment may vary slightly on older or non-standard decks. If you need exact OEM tolerances, stick with Craftsman/Husqvarna branded blades.

Key Things to Know

• Mulching performance: These blades have a curved, high-lift design to recirculate clippings. For best results, mow when grass is dry and don’t cut more than 1/3 of blade height.
• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). Always disconnect the spark plug and block the deck before removing blades.
• Common gotcha: The 7-point star center may not fit all spindle hubs. If your current blade uses a different center shape (e.g., 5-point star, oval, or round), these won’t work.
• Durability: Heat-treated steel holds an edge reasonably well for a season of typical residential use. Sharpen or replace annually.

Should You Buy It

If you have a 38-inch deck riding mower from Craftsman, Poulan, or Husqvarna with the listed OEM part numbers and want an affordable mulching upgrade, these are a solid buy. Skip them if you need a standard lift blade for bagging or side discharge, or if your deck uses a non-star center hole.
