4PK Oregon 198-059 Blade for 42" MTD Troy-Bilt Cub Cadet 742-0616, 942-0616

What It Is

This is a set of four 42-inch OEM-replacement mower blades designed for select MTD, Troy-Bilt, and Cub Cadet riding mowers with 42-inch cutting decks. They’re ideal for residential lawn care and medium-duty mulching or bagging.

Fitment & Compatibility

Before buying, verify your deck size is exactly 42 inches (not 46" or 50"). These blades directly replace OEM part numbers 742-0616 and 942-0616. They fit many Cub Cadet, MTD, and Troy-Bilt models from the early 2000s onward, including LT, LX, and RZT series. Measure your current blade length (should be ~20.5 inches), center hole diameter (1-inch), and ensure the blade orientation (offset or straight) matches your deck. Check your owner’s manual or look up your model number on Oregon’s site to confirm. Aftermarket Oregon blades are a reliable, often cheaper alternative to OEM.

Key Things to Know

• Quality & durability: Oregon blades are known for good steel and edge retention—expect 2-3 seasons of typical residential use before needing replacement.
• Installation: Straightforward if you have a socket set and jack stands. Always disconnect the spark plug and use a blade removal tool to avoid spinning. Tighten to 70-80 ft-lbs.
• Gotcha: These blades are not universal—they won’t fit decks with different spindle spacing or center hole sizes. Double-check your spindle count (four on 42" decks).
• Mulching vs. bagging: They work for both, but if you need high-lift bagging, consider Oregon’s high-lift version instead.

Should You Buy It

If you own a 42-inch MTD, Troy-Bilt, or Cub Cadet mower and need a reliable, affordable blade set that matches OEM specs, this is a solid buy. It’s best for homeowners who want OEM-like performance without the premium price. Skip it if your deck is a different size or you need specialized high-lift blades for heavy wet grass.
