8TEN LawnRAZOR Mower Blade for MTD Cub Cadet RZT S54 L54 Troy Bilt 54 inch Deck 942-05056A 942-05056 (High Lift) 9 Pack

What It Is

This is a 9-pack of high-lift replacement blades for 54-inch mower decks, designed for MTD-built tractors like Cub Cadet RZT S54, L54, and Troy-Bilt models. The high-lift design improves grass clipping discharge and bagging performance, especially in tall or damp grass.

Fitment & Compatibility

Before buying, confirm your deck is exactly 54 inches wide—this pack fits only that size. Check your OEM part number: these replace 942-05056A and 942-05056. They fit Cub Cadet RZT S54, RZT L54, and select Troy-Bilt 54-inch zero-turn models. Also verify the blade center hole diameter (usually 7/8-inch or 1-inch) and overall length (about 18.5 inches). Measure your old blade to be sure. Aftermarket blades may vary slightly in thickness or balance from OEM, so compare the original visually.

Key Things to Know

• High lift = better bagging, harder on engine: These blades create more lift for superior grass evacuation, but they also increase drag—expect slightly higher fuel consumption and more strain on the deck belt.
• Installation tip: Use a blade removal tool or block of wood to prevent the blade from spinning. Torque the blade bolt to 70-90 ft-lbs (check your manual). Do not overtighten.
• Balance check: Aftermarket blades sometimes need balancing. Use a simple blade balancer to avoid vibration that can damage the spindle.
• Sharpening: These are high-lift, so sharpening the top edge is critical for lift performance. Don’t just grind the bottom edge.

Should You Buy It

If you own a Cub Cadet or Troy-Bilt 54-inch zero-turn and need a bulk set of high-lift blades for frequent mowing in thick grass, this pack delivers value and consistent performance. It’s not for standard lift or mulching applications—stick with this if you want maximum discharge and bagging efficiency.
