Set of 2 Lawn Mower Blades Fits 42" Craftsman T105 T110 T130 T1400 T1200 T1300 T1100 T1800 T2100

What It Is

This is a set of two replacement mower blades designed for 42-inch cutting decks on Craftsman T-series lawn tractors (T105, T110, T130, T1400, T1200, T1300, T1100, T1800, T2100). They are high-lift blades intended for bagging or side-discharge mowing on residential turf.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches wide (measured blade tip to blade tip). These blades fit Craftsman T-series tractors with a 42" stamped deck, typically from late 2000s through current models. They are not compatible with 46" or 54" decks, or with Craftsman mowers using a different spindle pattern (e.g., LT1000 series). Measure your existing blade length: these are 21 inches long, with a 1-inch center hole and a 5-point star drive pattern. If your blade has a different center hole shape (e.g., oval or round), these won’t fit. Check your OEM part number—these replace Craftsman 532-175584, 532-175585, and 532-175586.

Key Things to Know

• Quality – These are aftermarket blades, not OEM Craftsman. They are made from hardened steel but may not have the same durability or balance as factory blades. Expect a slightly shorter lifespan under heavy use.
• Installation difficulty – Easy for DIYers. You’ll need a socket wrench, a torque wrench (set to 70-90 ft-lbs), and a blade removal tool or block of wood to keep the blade from spinning. Always lift the deck and disconnect the spark plug first.
• Common gotchas – The 5-point star center hole can be tight on some spindles; tap gently with a hammer to seat it. Do not overtighten—this can strip the spindle threads. Re-sharpen or replace after 25 hours of use or when grass tears instead of cuts.
• Balance – After installing, spin the blade by hand to check for wobble. An unbalanced blade causes vibration, poor cut quality, and spindle wear. If it wobbles, return or exchange.

Should You Buy It

These are a budget-friendly option if you need two blades quickly and don’t mind aftermarket quality. They’re fine for light-to-medium residential mowing on a Craftsman T-series tractor with a 42" deck. If you mow tough, thick grass or want maximum longevity, spend more on OEM Craftsman blades. For most homeowners, these will do the job without issues.
