Hipa 2-Pack 942-04385 Mulching Blades 6 Point Star Set for Troy Bilt Craftsman 30 inch Deck Lawn Mower R110 R1000 TB30R TB30 Cub Cadet CC30 CC30H Mower Blades Replace 742-04385 490-110-C135

What It Is

This is a 2-pack of mulching blades designed for 30-inch cutting decks on lawn tractors. They use a 6-point star center hole and are meant to replace OEM blades on Troy-Bilt, Craftsman, Cub Cadet, and similar models.

Fitment & Compatibility

Before buying, confirm your mower has a 30-inch deck and a 6-point star spindle (not a standard 5-point star or round hole). This set replaces OEM part numbers 742-04385 and 490-110-C135. Compatible models include: Troy-Bilt R110, R1000, TB30R; Craftsman T110, T1000; Cub Cadet CC30, CC30H, LT1040, RZT50. Double-check your deck size – many tractors sold as “30-inch” actually have 42-inch or 46-inch decks. Also verify blade length: these are 15.5 inches long, 2.25 inches wide, with a 0.22-inch thickness. If your existing blades are longer or shorter, these won’t fit.

Key Things to Know

• Mulching vs. bagging: These blades have a curved, high-lift design to recut clippings finely. They work best for mulching; for bagging, use standard blades.
• Installation difficulty: Easy – just a socket and torque wrench. Torque the center bolt to 35-45 ft-lbs. Use a blade stop or block of wood to prevent spinning.
• Common gotcha: The 6-point star hole is not universal. Some older Craftsman or Cub Cadets use a 5-point star or a round hole with a keyway. Measure your spindle before buying.
• Quality: Made from heat-treated steel, reportedly durable and balanced out of the box. A few users note they may need minor balancing for perfect smoothness.

Should You Buy It

If you own a 30-inch deck Troy-Bilt, Craftsman, or Cub Cadet with a 6-point star spindle and want a solid mulching blade at a fair price, this set is a direct fit. It’s a good value for the price, especially if you’re replacing worn OEM blades. For other deck sizes or spindle types, look elsewhere.
