What It Is

This is a high-lift mower blade compatible with specific Cub Cadet, RZT, and MTD models using a 42-inch deck. Designed for better grass clipping discharge and bagging performance, it’s a direct replacement for OEM part numbers 742-04308, 742-04312, and 742-0656.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be 42 inches. Measure your deck width (cutting swath) to confirm.
• Model fit: Works with Cub Cadet RZT series, MTD LT2000, T1100, LT1500, T1000, T1200, T1300, LT-135, T1400, T2100, T1800. Also fits select RZT models with a 42-inch deck.
• OEM cross-reference: Replaces OEM part numbers 742-04308, 742-04312, and 742-0656. If your mower uses a different OEM blade number, measure center hole diameter (typically 5/8” or 7/8”) and blade length (around 21 inches) to confirm.

Key Things to Know

• High-lift design – Curved edges create more airflow, improving bagging and side discharge, but may increase engine load on thick or wet grass.
• Installation difficulty – Easy for DIYers; requires a socket wrench and torque wrench (tighten to 70-80 ft-lbs). Use thread locker if bolts are worn.
• Common gotcha – These blades are not universal; they only fit the listed 42-inch decks. Check for a spindle adapter if your deck uses an offset hole pattern.
• Quality note – Made from hardened steel, but aftermarket blades may be slightly thinner than OEM. Inspect for balanced weight before mounting.

Should You Buy It

If you own one of the listed Cub Cadet or MTD models with a 42-inch deck and need a high-lift blade for better bagging or discharge performance, this is a reliable, well-rated replacement at a fair price. Avoid if you have a different deck size or need a standard (low-lift) blade for mulching.
