2PK USA Mower Blades for 46" Craftsman T140 13AL78XT093 CMXGRAM201304

What It Is

This is a 2-pack of replacement mower blades designed for 46-inch cutting decks, specifically for Craftsman T140 lawn tractors and compatible models. They are for residential mowing on standard turf grass, not heavy commercial use.

Fitment & Compatibility

Before buying, verify three things: your mower deck is exactly 46 inches (measure if unsure), your model number matches the T140 series (e.g., 13AL78XT093, CMXGRAM201304), and the blade dimensions: 18.25 inches long, 2.5 inches wide, with a 0.25-inch center hole and a 7-point star drive. These are aftermarket blades, not OEM Craftsman, but are designed to be a direct replacement for OEM part numbers 742P05559, 742-05559, and 742P05560. Check that your spindle pattern uses a star center—not a round hole or oval slot.

Key Things to Know

• Quality: Made from heat-treated carbon steel (Boron steel), these are tougher than standard stamped blades and hold an edge longer, but still wear faster than high-end aftermarket options.
• Installation: Easy DIY swap—requires a socket wrench and torque wrench (50-60 ft-lbs). Use thread locker on bolts to prevent loosening. Lift the deck safely, block it, and disconnect the spark plug.
• Common Gotcha: The star drive center must align perfectly with your spindle. If your deck uses a different drive pattern (e.g., five-point or oval), these won’t fit.
• Balance: Each blade is individually balanced, but always check balance after sharpening or if you hit an obstacle—unbalanced blades cause vibration and uneven cut.

Should You Buy It

If you own a 46-inch Craftsman T140 tractor, this is a solid, cost-effective replacement that matches OEM specs. It’s ideal for homeowners wanting reliable, easy installation without paying premium OEM prices. Avoid if you need commercial-grade durability or have a different deck size.
