942-04308-X Blades 6 Point Star for Cub Cadet XT1 XT2 LX42 LT42 ZT1 RZT Zero Turn Lawn Tractor for Troy Bilt Bronco Pony Mustang Craftsman T110 42" Deck 942-04308 942-04312 Toothed Blade Blades 2 Pack

What It Is

This is a 2-pack of 42-inch deck blades with a 6-point star center hole, designed for Cub Cadet XT1, XT2, LX42, LT42, ZT1, and RZT zero-turn mowers, plus Troy-Bilt Bronco/Pony/Mustang and Craftsman T110 models. They replace OEM part numbers 942-04308 and 942-04312 for standard cutting and mulching.

Fitment & Compatibility

• Deck size: Only fits 42-inch cutting decks—measure your deck width before buying.
• Center hole: 6-point star (not round or 5-point). Verify your spindle’s shape; some older decks use a round hole.
• OEM vs aftermarket: These are OEM-style replacements, not genuine Cub Cadet. They match the original length (approx. 20.5 inches) and thickness (0.25 inch) but may have slight finish differences.
• Models: Works on Cub Cadet XT1/LT42, Troy-Bilt Bronco (42”), Craftsman T110, and similar MTD-built tractors with 42” decks. Check your owner’s manual for 942-04308 or 942-04312 part numbers.
• What to measure: Blade length, center hole shape, and bolt pattern (usually a 5/8-inch or 3/4-inch hole with a star). Also check the spindle bolt size—most use 5/8-inch or 3/4-inch hex.

Key Things to Know

• Installation difficulty: Easy—1 out of 5. You’ll need a socket wrench and a block of wood to lock the blade. Torque spindle bolts to 70-90 ft-lbs.
• Sharpness out of box: Blades come sharp but not razor-edged. You may want to sharpen them for a cleaner cut, especially on mulching.
• Balance: Check balance after sharpening; an unbalanced blade causes vibration and spindle wear. Use a blade balancer or nail-in-wall trick.
• Common gotcha: The star hole might be tight on some spindles. If it doesn’t slide on, lightly file the spindle or hole—don’t force it, or you’ll strip the star.

Should You Buy It

Buy these if you own a Cub Cadet, Troy-Bilt, or Craftsman 42” mower with a 6-point star spindle and want a budget-friendly replacement for worn or damaged blades. They’re a solid value for standard cutting and light mulching, but skip them if you need premium high-lift blades for bagging or have a 46” or 54” deck.
