942-04244-X 46 Inch Mower Blades for Cub Cadet XT1 LT46 LTX1045 LTX 1046 RZT L46 XT2 LX 46 ZT1-46 Troy Bilt Mustang XP46 742-04290-X 46" Deck Zero-Turn Lawn Tractor 6 Point Star Toothed Mulching 2 PCS

What It Is

This is a set of two 46-inch mulching blades designed for Cub Cadet, Troy Bilt, and compatible zero-turn lawn tractors with a 46-inch deck and a 6-point star (splined) spindle mount. They’re intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch cutting deck and a 6-point star (splined) spindle—not a standard oval or 5-point star hole. Key compatible models include:

• Cub Cadet XT1 LT46, LTX1045, LTX1046, RZT L46, XT2 LX 46, ZT1-46
• Troy Bilt Mustang XP46
• Also fits models using OEM part numbers 942-04244-X or 742-04290-X

Measure your current blade length (should be ~18.25 inches) and verify the center hole diameter (typically 7/16” or 1/2”). This is an aftermarket replacement, not OEM Cub Cadet, but uses the same specs. If your deck has a different spindle pattern (e.g., 5-point star or oval), this set won’t fit.

Key Things to Know

• Mulching vs. standard blades: These have a curved, high-lift design that recirculates clippings for finer mulching. They won’t discharge as well if you prefer bagging or side-discharge.
• Installation difficulty: Easy if you have a socket wrench and a blade removal tool. Tighten to 70-90 ft-lbs. Check blade direction—cutting edge should face the direction of rotation.
• Common gotcha: The 6-point star mount is less common than 5-point. Double-check your spindle by removing one existing blade. If the hole looks like a star with 6 points (not 5), you’re good.
• Quality: 4.7/5 rating suggests good durability and sharpness out of the box, but aftermarket blades may need re-sharpening sooner than OEM.

Should You Buy It

Buy these if you have a compatible Cub Cadet or Troy Bilt 46-inch zero-turn or lawn tractor with a 6-point star spindle and want affordable mulching blades that perform well for the price. Skip if you need OEM exact fit, bagging-specific blades, or have a 5-point star or oval spindle.
