561713B 138971 Mower Blades 42 Inch Deck Compatible for Craftsman LT1000 LT2000 T110 DLT3000 T2200 YT3000 Compatible for Poulan Compatible for 532138971

What It Is

This is a set of three 42-inch replacement mower blades designed for riding lawn mowers with a 42-inch cutting deck. They are a direct aftermarket match for Craftsman LT1000, LT2000, T110, DLT3000, T2200, YT3000 series tractors, as well as compatible with certain Poulan models using OEM part 532138971.

Fitment & Compatibility

Before buying, verify these three critical points:

• Deck size: Your mower must have a 42-inch cutting deck. Measure deck width if unsure—this blade set will not fit 46-inch or 54-inch decks.
• OEM part cross-check: The blades replace Craftsman/Poulan OEM part 532138971 (also listed as 561713B or 138971). Check your owner’s manual or current blade for this number.
• Blade dimensions: Each blade is roughly 21 inches long with a 1-inch center hole and a 7-point star drive. Measure your old blade’s length, center hole diameter, and drive pattern to confirm fit.
• Model compatibility: Direct fit on Craftsman LT1000, LT2000, T110, DLT3000, T2200, YT3000, and many Poulan 42-inch deck models. Not for zero-turn or walk-behind mowers.

Key Things to Know

• Quality: Aftermarket blades are typically made from stamped steel—adequate for regular residential use but may dull faster than OEM or premium hardened steel blades. Expect 1-2 seasons with normal mowing.
• Installation difficulty: Easy to moderate. You’ll need a socket wrench and a torque wrench (tighten to 70-90 ft-lbs). Always lift the deck safely and block it before working underneath.
• Common gotcha: The star drive pattern must match your spindle. Some older Craftsman decks use a 5-point star, not 7-point. Check your spindle before buying.
• Balance: Aftermarket blades are often not pre-balanced. You may need to check balance with a blade balancer and file the heavy side. Unbalanced blades cause vibration and spindle wear.

Should You Buy It

If you own a Craftsman or Poulan 42-inch deck lawn tractor and need a budget-friendly replacement set for regular residential mowing, this is a solid value. It’s not for heavy-duty commercial use or for decks that require a different drive pattern. For the price, it’s a direct fit that gets the job done—just check your spindle star count and balance the blades before installing.
