Mr Mower Parts Mulcher Blade Set Compatible with CUB Cadet MTD 742P05094-X 742P05094 742P05094X Xtreme 17-1/4" Blade Diamond Shape Fits S-Shaped - 3 Pack

What It Is

This is a set of three mulcher blades designed for Cub Cadet and MTD lawn tractors with 17-1/4" decks. They feature a diamond-shaped cutting edge and an S-shaped wing profile to chop clippings finely for nutrient recycling.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits 17-1/4" (17.25") cutting decks only. Measure your blade length from tip to tip.
• OEM cross-reference: Replaces Cub Cadet/MTD part numbers 742P05094-X, 742P05094, and 742P05094X. Verify your machine’s OEM part number on the old blade or in the manual.
• Center hole & mounting: Diamond-shaped center hole fits S-shaped spindle mounts common on many Cub Cadet and MTD tractors. Confirm your spindle uses an S-pattern (not a star or oval).
• Brand fit: Designed for Cub Cadet and MTD models, but may fit other brands with the same blade length and mounting pattern. Always measure your existing blade.

Key Things to Know

• Mulching vs. bagging: These blades are optimized for mulching—they create finer clippings that decompose quickly. Not ideal for bagging (may clog).
• Installation torque: Tighten to 40-50 ft-lbs. Use a torque wrench; overtightening can strip the spindle.
• Balance check: New blades are balanced from the factory, but it’s good practice to check balance after sharpening. An unbalanced blade causes vibration and spindle wear.
• Sharpness: Arrive sharp but dull faster than standard blades due to the aggressive cutting edge. Plan to sharpen every 10-15 hours of use.

Should You Buy It

Buy this if you have a Cub Cadet or MTD tractor with a 17-1/4" deck and want to improve lawn health through fine mulching. It’s a solid value at $44 for three blades, and the 4.7-star rating confirms reliable fit and performance. Avoid if you primarily bag clippings or need a standard lift blade for tall grass.
