These MTD Genuine Parts 942-04385 3-in-1 mulching blades are replacement 30-inch blades engineered to deliver consistent cutting and fine mulching for compatible lawn tractors.

Upgrade your mower with a set of heavy-duty 30-inch mulching blades designed for reliable fit and efficient grass processing. The 942-04385 blades are built to match original-equipment performance for many popular mower models from Troy-Bilt, Murray, Columbia and similar brands.

How will these blades change my mowing results?

These blades are shaped to lift, cut, and recirculate clippings so they break down faster and spread more evenly across the lawn. Expect fewer clumps, a more uniform finish, and less time spent bagging. They’re optimized for a 30-inch deck to maintain consistent coverage with each pass.

• Three cutting surfaces for improved mulching action
• Curved profile that promotes airflow and clip recirculation
• Reduces bagging by producing finer clippings
• Designed to maintain cut quality across varying grass lengths

Will these blades fit my mower and how do I confirm compatibility?

The blades are manufactured to match common 30-inch mower specifications and include a star-shaped center hole to align with compatible spindle shafts. Always cross-check your mower’s parts list or the label under the rider seat and consult your operator’s manual for exact part numbers before ordering.

• Fits many Troy-Bilt, Murray, Columbia models and other makes with 30" decks
• Star center hole ensures proper indexing on the spindle
• Replacement numbers listed to compare with OEM references

How durable are these replacement blades and what maintenance do they need?

Constructed for frequent mowing conditions, these blades balance toughness and edge retention so they remain serviceable across multiple seasons. Regular inspections and sharpening extend blade life; replace if you spot major bends, cracks, or excessive thinning at the edge.

• Heavy-gauge steel resists deformation during normal use
• Sharpen periodically to maintain clean cuts and reduce turf stress
• Inspect for damage after impacts and replace if compromised

What tools or steps are needed to install these blades safely?

Installation is straightforward if you follow your mower’s safety procedures: disconnect spark plug, raise or tilt the machine per the manual, remove the old blades, and mount the new ones with the correct orientation. Use a torque wrench to tighten bolts to the specified value and verify blade clearance before resuming mowing.
