Hipa 942-04308 Mulching Blades for Cub Cadet XT1 LT42 42 Inch Mower Blades | 2-Pack 6 Point Star Blades for Troy Bilt Bronco Pony 42'' Deck Lawn Tractor Ultima ZT1 RZT42 42 inch Mower Replace 942-0616

What It Is

This is a 2-pack of mulching blades (model 942-04308) designed to replace OEM 942-0616 blades on 42-inch cutting decks. They fit Cub Cadet, Troy-Bilt, and select MTD-built lawn tractors and zero-turn mowers, intended for fine clippings that decompose quickly.

Fitment & Compatibility

• Deck size: Only fits 42-inch decks. Measure your deck width before ordering.
• Brand/model: Cub Cadet XT1 LT42, Ultima ZT1, RZT42; Troy-Bilt Bronco Pony, Pony 42; also fits some Craftsman and Husqvarna models with 6-point star spindle mounts.
• OEM cross-reference: Replaces 942-0616 (OEM Cub Cadet/Troy-Bilt). Aftermarket alternative.
• Measurements: Blade length is 20.5 inches, center hole 1 inch, 6-point star drive. Verify your spindle has a 6-point star (not a 5-point or keyed shaft).
• What to check: Pull one existing blade and confirm the star pattern and length. If your spindle uses a 5-point star, these won’t mount.

Key Things to Know

• Quality: Heat-treated steel with a coated finish for rust resistance. Users report good balance out of the box, but always check with a blade balancer.
• Installation: Straightforward swap—use a torque wrench to 45-55 ft-lbs. The star pattern centers the blade automatically.
• Mulching vs. bagging: These are dedicated mulching blades (curved, with more lift). Not ideal for bagging—use OEM high-lift blades if you bag often.
• Gotcha: Some users note slight vibration if the blade isn’t seated fully on the star. Ensure the star aligns completely before tightening.

Should You Buy It

If you own a Cub Cadet or Troy-Bilt 42-inch deck with a 6-point star spindle and want affordable, effective mulching blades, this 2-pack is a solid value. It’s not for bagging or side-discharge use, but for fine mulching in grass up to 4 inches tall, it performs well at half the cost of OEM.
