MTD Genuine Parts 42-inch 3-in-1 Blade Set — two-blade kit for mulching, bagging & side discharge

MTD Genuine Parts 42" 3-in-1 Blade Set is a two-blade replacement kit that enables mulching, bagging and side discharge for compatible 42" mower decks.

Keep your 42" lawn tractor working like new with this purpose-built blade set from MTD Genuine Parts. The kit contains two precisely balanced blades engineered to restore cutting performance on deep 42" decks and to switch between mulching, bagging, and side-discharge configurations. Designed as direct replacements for multiple OEM part numbers, these blades are a practical service item for routine maintenance and seasonal tune-ups.

What does "3-in-1" mean for my mowing options?

The 3-in-1 designation means each blade is shaped and balanced to support three common discharge setups: mulching finely clippings back into the lawn, channeling clippings into a rear bag, or directing cut material out the side of the deck. You’ll get versatile performance without needing separate blade types for each mode.

• Mulch: recuts clippings for faster decomposition and a tidy finish
• Bag: optimized airflow for consistent collection in rear bags
• Side discharge: clears heavy material quickly when bagging isn’t practical
