UDC Parts 942-04244A Mower Blades Replacement for Enduro Cub Cadet 46 Inch LT46 XT1 XT2 LTX 1046 942-04290A RZT L46 Troy Bilt Craftsman T240 742-04290 / Mulching 6 Point Star / 2 Pack

What It Is

This is a set of two 46-inch mulching blades with a 6-point star center hole, designed for medium-duty residential mowing on Cub Cadet, Troy-Bilt, and Craftsman lawn tractors. They replace OEM part numbers 942-04244A, 942-04290A, and 742-04290, and are intended for mulching grass clippings rather than bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 46 inches and uses a 6-point star (hex) spindle hole. These blades fit Cub Cadet Enduro Series LT46, XT1, XT2, LTX 1046, and RZT L46, plus Troy-Bilt Pony, TB46, and Craftsman T240. They will not fit decks with a round center hole or 5-point star. Double-check your current blade’s part number—if it ends in 942-04244A, 942-04290A, or 742-04290, this is a direct swap. Measure blade length (should be ~21.5 inches) and thickness (~0.25 inches) to match your old blade.

Key Things to Know

• Mulching vs. standard: These blades have a curved, serrated design to chop clippings finer. If you bag or discharge, look for a standard lift blade instead.
• Installation: Requires a socket wrench and torque wrench (40-50 ft-lbs). Use thread locker on the bolts to prevent loosening. The 6-point star must align perfectly with the spindle—if it doesn’t slide on easily, it’s the wrong part.
• Quality notes: Made from heat-treated steel, but some users report they dull faster than OEM blades after heavy use or hitting rocks. Inspect after every 10-15 hours of mowing.
• Balance: Always check blade balance after sharpening or replacement. An unbalanced blade causes vibration and spindle wear.

Should You Buy It

Buy this if you own a 46-inch Cub Cadet, Troy-Bilt, or Craftsman tractor with a 6-point star spindle and primarily mulch your lawn. It’s a solid value at under $30 for a pair, with strong user reviews confirming good fitment and decent durability for residential use. Skip it if you bag often or need a heavy-duty blade for rocky terrain.
