4PK Oregon 98-629 G3 Mulching Gator Blades for 42" Craftsman T110 13AN77XS093

What It Is

This is a set of four Oregon 98-629 G3 Mulching Gator blades designed to replace the stock blades on a 42-inch cutting deck, specifically for Craftsman T110 and similar tractors like the 13AN77XS093. They are aftermarket, high-lift mulching blades that chop clippings finer than standard blades, ideal for lawns where bagging or leaving fine mulch is preferred.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 42 inches (107 cm) – these blades are not for 46" or 54" decks.
• Model number: Check your tractor’s model tag (e.g., 13AN77XS093). This set fits Craftsman T110, T120, and some Husqvarna/MTD models with a 42" stamped deck. Not compatible with zero-turn mowers or older Craftsman models with 42" fabricated decks.
• Blade measurements: Each blade is 21.5" long, 2.5" wide, with a 5-point star center hole (1" diameter) and 0.25" thick. Measure your old blade’s length and center hole shape to confirm.
• OEM vs aftermarket: Oregon is a respected aftermarket brand. These replace OEM part numbers 532185842, 532185843, 532185844, or 532185845. They are not OEM, but fit and function identically.

Key Things to Know

• Quality: Oregon G3 blades are heat-treated and hardened, lasting 2-3x longer than stock blades when used on clean, dry grass. They resist bending on small debris better than thin OEM blades.
• Installation difficulty: Moderate (30-60 minutes). You’ll need a 15/16" socket, torque wrench, and jack/ramps to lift the mower safely. Always disconnect the spark plug first.
• Common gotcha: The G3 blades are heavier than stock (about 1.5 lbs each vs 1.2 lbs). This can cause slight vibration if one blade is not balanced. Use a blade balancer after installation.
• Mulch vs bag: These create very fine mulch but reduce bagging efficiency. If you bag frequently, consider the Oregon G5 (less lift) or stick with OEM.

Should You Buy It

Buy this set if you own a Craftsman T110 or compatible 42" tractor, mow weekly or biweekly, and want a significant upgrade in mulching quality without paying OEM prices. It’s a solid value for homeowners who don’t bag and want a cleaner-looking lawn with fewer clumps. Skip it if you bag 90% of the time or have a 46"+ deck.
