UDC Parts Mulching Blades Replacement for 38" Lawn Mower Deck, 2-Pack - OEM Fit, High-Strength Steel

These UDC Parts 942-0610A mulching blades are a two-pack direct replacement designed to fit 38-inch decks on Cub Cadet, MTD, Troy-Bilt, Huskee and many other lawn tractors.

When your mower’s cutting performance drops, worn or damaged blades are often the culprit. UDC Parts engineered these replacement blades to match OEM fitment and restore mulching and bagging efficiency for compatible 38" decks. Constructed from high-strength steel and formed to the same dimensions as the original 942-0610A/742-0610A blades, the set includes two blades so you can service both sides of a typical 38" deck in one installation.

Which machines will these blades fit?

These blades are made to replace OEM part numbers for a wide range of brands and models that use the 38-inch deck pattern. They match the star-shaped center hole, mounting hole spacing, and cutting edge geometry required by those decks. Fitment includes many MTD-family tractors and specific Murray, Cub Cadet, Troy-Bilt, Bolens, Yard Machines, Yard-Man, Huskee, White Outdoor, Columbia and Ranch King models.

• Compatible with OEMs: 942-0610A, 742-0610, 742-0610A and equivalents listed.
• Fits decks marked as 38" (diagonal blade length 19-5/16").
• Matches 6-point star center hole and 5/16" side holes.

How do these blades improve cutting and mulching?

The blade shape and air-lift features are designed to create the airflow needed for efficient mulching and uniform discharge. Sharp, properly pitched edges chop clippings finely and help disperse them back into the turf for quicker breakdown and a cleaner finish. Because they mirror OEM geometry, they preserve deck balance and clip distribution.

• Air lift profile promotes even clipping circulation under the deck.
• Pitched cutting edge produces finer mulch and smoother clippings.
• Durable steel resists bending for sustained performance.

What are the exact dimensions and mounting details?

Knowing the precise measurements helps confirm compatibility before purchase. These UDC blades report the same critical dimensions used by OEM 942-0610A and 742-0610A replacements so you can verify fit against your deck or old blade.

• Overall (diagonal) length: 19-5/16"; width: 3".
• Center: 6-point star hole measuring 2-1/2" across; side hole: 5/16".
• Center-to-center outside hole spacing: 2-1/2"; air lift height 1-3/8".

How should I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect spark plug, remove deck and old blades, verify orientation, and torque bolts to manufacturer specs. Routine inspection and sharpening when dull will prolong life and keep cutting performance consistent.

• Always disconnect spark and follow safety procedures before replacing blades.
• Check blade torque and use the original mounting hardware pattern.
• Sharpen periodically and replace if bent, cracked, or excessively worn.

Who is this for: Homeowners and small-property caretakers who use 38" deck lawn tractors and need a reliable, OEM-compatible mulching blade replacement. These blades suit anyone maintaining a Cub Cadet, MTD-family, Murray, Troy-Bilt or similar 38" mower deck who wants durable steel construction, correct mounting fit, and improved mulching performance without buying OEM-branded parts.
