What It Is

This 2-pack of 42-inch Gator mulching blades (model 532134149) is designed for select Craftsman and Husqvarna lawn tractors with 42-inch decks. Each blade includes a 532193003 bolt. They replace OEM part numbers 532138971, 532138498, and 532127843. The Gator-style wing design lifts grass for finer mulching and better bagging than standard blades.

Fitment & Compatibility

Before buying, verify your deck is exactly 42 inches (measured cutting width, not deck shell). These blades fit models YTH18542, YTH22V42, LT1000, YTA18542, and YTH1842, plus many Craftsman LT, GT, and DLT series with 42-inch decks. They also fit some Husqvarna YTH and GTH models using the same spindle pattern.

Must-check measurements:

• Center hole: 5/8 inch (oval or round)
• Blade length: 21 inches (end to end)
• Blade width: 2-1/4 inches
• Thickness: 0.203 inch (standard for most Craftsman 42-inch decks)
• Spindle pattern: 5-point star (fits most Craftsman and Husqvarna spindles)

If your current blades have a different center hole shape (e.g., diamond), these won’t fit. Always compare your old blade side-by-side with the new one.

Key Things to Know

• Quality: These are aftermarket, not OEM Craftsman. They’re made from heat-treated steel and hold an edge decently, but may wear faster than factory blades in heavy use. The Gator wing design improves mulching but can increase vibration if the deck is unbalanced.
• Installation difficulty: Easy (15-30 minutes). You’ll need a 15/16-inch socket or wrench for the blade bolt. Torque to 70-90 ft-lbs. The included bolts are standard grade 8—use anti-seize on threads to prevent rusting.
• Common gotchas: The “Gator” style blades are slightly heavier than standard, which can strain a weak spindle or belt. Check blade balance before installing—unbalanced blades cause deck shake. These are not for zero-turn mowers or decks smaller than 42 inches.
• Tip: Replace all blades at once (2-pack covers one deck). Reuse existing flat washers if your deck uses them; the included bolts are all you need.

Should You Buy It

If you own a 42-inch Craftsman or Husqvarna tractor with a standard 5/8-inch star spindle and want better mulching than stock blades, this is a solid budget pick. It’s not the longest-lasting option, but for $27 (2 blades + bolts), it’s a good value for homeowners mowing average lawns. Avoid if you need OEM durability for heavy commercial use or have a non-standard spindle pattern.
