CUB CADET 942-04385 Mower Blade CC30 H Hydro Mini Rider Lawn Mowers 30" Decks

What It Is

This is a replacement mower blade (OEM part number 942-04385) designed specifically for Cub Cadet CC30 H Hydro Mini Rider lawn mowers with 30-inch cutting decks. It’s a straight, medium-lift blade for mulching or bagging grass on residential zero-turn-style mini riders.

Fitment & Compatibility

• Deck size: Only fits 30-inch decks on Cub Cadet CC30 H Hydro Mini Rider models. Do not use on 32-inch, 34-inch, or any other deck width.
• Model check: Confirmed compatible with CC30 H Hydro (model series 13A9, 13A10). Not for older CC30 or non-hydro models.
• OEM vs aftermarket: This is a genuine Cub Cadet OEM blade. Aftermarket blades with the same part number (e.g., Oregon 91-043) may fit but can vary in thickness or balance.
• Measurements: Blade length is 15.25 inches, center hole diameter is 7/8 inch, and thickness is 0.1875 inches (3/16”). Verify these on your current blade before ordering.
• Quantity: Sold individually. You need two blades for a 30-inch deck.

Key Things to Know

• Quality: OEM blades are heat-treated and balanced for consistent cut. Aftermarket blades may wear faster or cause vibration.
• Installation difficulty: Easy—requires a socket wrench (usually 5/8-inch or 15/16-inch) and a blade removal tool. Torque to 35–45 ft-lbs.
• Common gotcha: The blade orientation is crucial—the lift edge must face upward toward the deck. Installing upside down will reduce cutting performance and risk damage.
• Sharpening: These blades are not designed for repeated sharpening; replace when nicked or dull (typically every 25–50 hours of use).

Should You Buy It

If you own a Cub Cadet CC30 H Hydro Mini Rider with a 30-inch deck and want a guaranteed fit and OEM performance, this blade is the right choice. It’s ideal for homeowners who prioritize reliability over saving a few dollars on generic options. Skip it if you have a different deck size or prefer aftermarket blades for cost savings.
