Mr Mower Parts Lawn Mower 30" Deck Blade Compatible with Cub Cadet 490-110-C135 490-110-M135 CMXGZAM110135 CC30 CC30H Hydro Mini Rider

What It Is

This is a 30-inch replacement deck blade for Cub Cadet CC30, CC30H Hydro, and Mini Rider lawn tractors. It’s designed for mid-size residential mowing—think weekly trimming on 1–2 acre lots with moderate grass conditions.

Fitment & Compatibility

• Deck size must be exactly 30 inches. Measure your existing blade tip-to-tip before ordering—this blade is not compatible with 32-inch or 42-inch decks.
• Direct OEM cross-reference: Cub Cadet 490-110-C135, 490-110-M135, and CMXGZAM110135. If your mower uses those part numbers, this blade fits.
• Aftermarket vs. OEM: This is an aftermarket blade. It matches OEM dimensions (length, center hole, offset) but is not Cub Cadet branded. Verify your spindle hole pattern matches (should be a 5-point star or standard oval) by checking your old blade’s center hole shape.
• Also fits: Some MTD-branded 30-inch decks with the same spindle design. If in doubt, compare blade thickness (usually 0.1875 inch) and lift height.

Key Things to Know

• Quality: Made from heat-treated carbon steel—durable for residential use, but not as hard as premium boron steel blades. Expect 2–3 seasons of normal mowing before needing replacement.
• Installation: Straightforward—remove the center bolt, swap blades, torque to 70–80 ft-lbs. Use a blade stop or block of wood to hold the blade. No special tools beyond a socket wrench.
• Common gotcha: The blade is pre-sharpened but not balanced. If you feel vibration after install, remove and balance it with a balancer tool—unbalanced blades wear spindles faster.
• Double-check lift: This blade has a moderate lift (approx. 1.5 inches). For thick, wet grass, a high-lift blade is better. For dry, dusty conditions, this works fine.

Should You Buy It

Yes, if you own a Cub Cadet CC30 or CC30H with a 30-inch deck and want a reliable, budget-friendly replacement that matches OEM specs. Skip it if you need a high-lift blade for heavy mulching or if your deck spindle uses a non-standard hole pattern—stick with OEM for those cases.
