Mr Mower Parts Mulching Blades 19-5/16" Compatible with AYP 134148 38" Deck Lawn Mower Blades 5 Point Star Center Hole Front Engine Rider 2-Pack

What It Is

This is a 2-pack of 19-5/16-inch mulching blades designed for 38-inch front-engine riding mower decks. They replace OEM part number 134148 and are intended for fine grass clipping mulching, not bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 38 inches (the blade length is 19-5/16" per blade, with a 5-point star center hole). These are aftermarket replacements for AYP/Sears/Craftsman models using OEM 134148. Check your current blade’s center hole shape—if it’s a 5-point star, these will fit. They do not fit universal round-hole or oval-hole spindles. Verify your mower’s make and model against the AYP 134148 cross-reference list.

Key Things to Know

• Quality: Made from heat-treated steel; sharpness and balance are generally good for the price, but inspect for warping before installation.
• Installation: Requires a torque wrench—tighten to 70-90 ft-lbs (check your manual). Use thread locker on the bolt to prevent loosening.
• Gotcha: Mulching blades have a higher lift than standard blades. If your deck lacks a mulching plug or baffle kit, clippings may clump or discharge poorly.
• Common issue: Star center holes can be tight on some spindles. File lightly if needed, but never force.

Should You Buy It

If you own a 38-inch AYP-based rider (Craftsman, Husqvarna, Poulan) with a 5-point star spindle and want an affordable mulching upgrade for fine clippings, this 2-pack is a solid value. Skip if you need bagging or side-discharge performance.
