Oregon 4PK Mulching Blade 198-049 Replacement for MTD 742-0741, 942-0741A, 742-0741A, 742-04276, Craftsman SPM209370365

What It Is

This is a set of four mulching blades designed for 20–22-inch walk-behind mowers with oval-center blade mounts. They replace several MTD and Craftsman OEM part numbers, allowing you to cut grass clippings into fine particles that decompose quickly back into the lawn.

Fitment & Compatibility

Before buying, confirm your mower has a 20 to 22-inch cutting deck and uses oval-center blades (not star or round). These blades replace MTD 742-0741, 942-0741A, 742-0741A, 742-04276, and Craftsman SPM209370365. They are not compatible with EGO-brand mowers (despite the brand name in the listing—this is an Oregon product). Measure your existing blade’s length, center hole shape, and width to ensure a match. Check your mower’s model number against the OEM part numbers listed above.

Key Things to Know

• Quality: Oregon is a respected aftermarket manufacturer; these blades are heat-treated and balanced for long life.
• Installation: Simple bolt-on replacement—requires a socket or wrench to remove the center bolt. No special tools needed.
• Gotcha: These are mulching blades, not standard lift blades. They will not discharge or bag as effectively—fine for mulching only.
• Common issue: Some users report the blades are slightly thicker than OEM, which may require a small spacer or washer if the bolt protrudes too far.

Should You Buy It

If you have a compatible MTD or Craftsman mower and want an affordable, well-rated mulching blade set that cuts clippings finely for lawn health, this is a solid choice. Avoid if you need bagging or side-discharge performance.
