Oregon 6PK 198-049 Mulch Blades for 21" MTD Cub Cadet Troy-Bilt 742-0741 942-0741

What It Is

This is a set of three Oregon 6PK 198-049 mulch blades designed for 21-inch walk-behind mowers. They replace OEM blades 742-0741 and 942-0741, and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting decks. Measure your deck width before buying.
• Brand/model fit: Compatible with MTD, Cub Cadet, Troy-Bilt, and other MTD-built mowers (e.g., Bolens, Yard-Man). Check your owner’s manual for 742-0741 or 942-0741 part numbers.
• OEM vs aftermarket: Oregon is a reputable aftermarket brand; these blades are direct replacements for OEM parts.
• Measurements: Blade length 21 inches, center hole 1 inch, star-shaped drive pattern. Verify your mower uses a star (not oval) center hole.
• Common models: Cub Cadet SC300, SC301, SC302; Troy-Bilt TB230, TB240; MTD 11A-283B229.

Key Things to Know

• Quality: Oregon blades are made from heat-treated steel and stay sharp longer than many OEM blades. They are balanced out of the box.
• Installation difficulty: Easy – you need a socket wrench and a block of wood to jam the blade. Torque to 35-40 ft-lbs. The star pattern ensures correct orientation.
• Common gotchas: These are mulch-only blades – they won’t bag or side-discharge well. If you switch between modes, you’ll need a separate set of lift blades. Also, check that your mower’s blade adapter is a star drive; some older MTD decks use a different pattern.
• Price vs OEM: At ~$45 for three blades, this is cheaper than buying OEM singles (often $20 each). You get a spare set.

Should You Buy It

Yes, if you have a 21-inch MTD-built mower with a star-drive blade mount and you want dedicated mulching blades that last. It’s a solid value for mulching-only use, but skip it if you need bagging or discharge capability.
