942-04308-X 42 Inch for Cub Cadet RZT 42 XT1 LT42 LT42 KH XT2 LX42 LX42 KH LT1042 LTX1040 42" Deck Zero-Turn Lawn Mower Craftsman LT1500 T1000 Troy Bilt 6 Point Star Mulching Toothed 3-IN-1 Blade 2PCS

What It Is

This is a set of two 42-inch, 6-point star mulching blades designed for 42-inch deck zero-turn and lawn tractors from Cub Cadet, Craftsman, and Troy-Bilt. The 3-in-1 design allows bagging, side discharge, or mulching, with the toothed edge helping to chop clippings finer for better nutrient recycling.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 42 inches (cutting width) and that your mower uses a center hole with a 6-point star drive (not a standard oval or diamond hole). This blade fits Cub Cadet models like RZT 42, XT1, LT42, LT42 KH, XT2, LX42, LX42 KH, LT1042, LTX1040, and also Craftsman LT1500, T1000, and Troy-Bilt equivalents. Check your current blade’s part number—OEM replacements include 942-04308, 942-04308X, or 742-04308. Measure blade length, width, and center hole diameter (typically 1-inch or 5/8-inch star) to avoid mismatch. Aftermarket blades may vary slightly in thickness or balance; inspect for burrs before install.

Key Things to Know

• Quality: Users report sharp edges and good balance out of the box, but always check for vibration after installation—rebalance if needed.
• Installation: Requires a socket or wrench for the center bolt; use a blade removal tool or block of wood to lock the blade. Torque to manufacturer spec (typically 70-90 ft-lbs). No special skills needed.
• Common gotchas: The 6-point star center hole is not universal—some Craftsman or Troy-Bilt decks use a 5-point star or oval hole. Verify your spindle’s drive pattern. Also, mulching performance improves with a mulching plug or cover; without it, clippings may clump in wet grass.
• Maintenance: Sharpen or replace after 25-50 hours of use, or sooner if hitting rocks or roots. Dull blades tear grass, causing browning.

Should You Buy It

If you own a 42-inch Cub Cadet, Craftsman, or Troy-Bilt with a 6-point star spindle and want a budget-friendly, high-rated mulching upgrade, this is a solid pick. It’s not for standard oval-hole decks or decks smaller/larger than 42 inches. For the price and near-perfect reviews, it’s a reliable replacement that delivers better mulching than OEM flat blades.
