8TEN LawnRAZOR Mower Blade Set for AYP Husqvarna 138498 532138971 532127843 532138498 42 inch Deck (Toothed)

What It Is

This is a set of three toothed (mulching) mower blades designed for 42-inch cutting decks, specifically for AYP (American Yard Products) and Husqvarna tractors. They replace OEM part numbers 138498, 532138971, 532127843, and 532138498, and are meant for mulching grass clippings into fine particles for lawn feeding.

Fitment & Compatibility

• Deck size: 42 inches only. Measure your deck’s cutting width before buying.
• Model fit: Fits Husqvarna, Poulan, Craftsman, and other AYP-built tractors with a 42-inch deck that use the OEM numbers above. Common models include Husqvarna YTH24V48, Poulan PPB460, and Craftsman 917 series.
• OEM cross-reference: Directly replaces Husqvarna/AYP parts 138498, 532138971, 532127843, 532138498.
• Physical specs: Each blade is 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch offset. Check your existing blade’s length, hole size, and offset to confirm match.
• What to verify: Count your blade spindles—this is a 3-blade set. If your deck uses 2 blades, this won’t fit.

Key Things to Know

• Mulching vs. bagging: These are toothed mulching blades, not lift blades. They chop clippings finer but won’t throw grass into a bagger as effectively as standard lift blades.
• Installation: Moderate difficulty. You’ll need a torque wrench (blade bolt torque: 70-90 ft-lbs typical). Lift deck safely, block it, and use a blade lock or wood block to prevent spinning.
• Balance: 8TEN blades come pre-balanced, but check with a blade balancer after install—vibration from an out-of-balance blade can damage spindles.
• Sharpness: They arrive sharp but dull faster than OEM blades on rough terrain. Sharpen after 10-15 hours of use for best mulching.

Should You Buy It

Buy this if you have a 42-inch AYP/Husqvarna tractor, want to mulch clippings instead of bagging, and prefer a cost-effective aftermarket set over OEM. Skip it if you need high-lift blades for bagging or have a different deck size.
