8TEN Spindle Toothed Blade Kit for MTD Cub Cadet 46 inch Deck LTX1045 LTX1046 LTX2046M Tractors

What It Is

The 8TEN Spindle Toothed Blade Kit is a set of three replacement blades designed for 46-inch deck MTD and Cub Cadet lawn tractors, intended for heavy-duty mulching and bagging on residential properties.

Fitment & Compatibility

Before purchasing, verify three things: (1) your deck measures exactly 46 inches from blade tip to blade tip—measure your current blades or deck housing; (2) your tractor model is among the listed LTX1045, LTX1046, or LTX2046M, or other MTD/Cub Cadet models with a 46-inch stamped deck; (3) the blade length is approximately 20.5 inches with a 1-inch center hole and 5-point star drive pattern. This is an aftermarket kit, not OEM Cub Cadet, but it replaces OEM part numbers 742-04022, 742-04022A, 742-04022B, and 742-04022C. Check your owner’s manual or existing blade part number for exact match.

Key Things to Know

• Quality vs. OEM: 8TEN uses heat-treated steel; reviews note comparable durability to factory blades, but some users report slightly faster dulling under heavy use.
• Installation: Moderate difficulty—you’ll need a socket set and a torque wrench (recommended 70–80 ft-lbs). The star drive pattern helps prevent slipping but requires careful alignment.
• Common Gotcha: These blades are toothed/mulching design, not standard lift blades—if you primarily side-discharge, they may leave clippings less evenly. For mulching or bagging, they perform well.
• Balance Check: Always balance blades after installation using a simple balancer; unbalanced blades cause vibration and damage spindles.

Should You Buy It

Buy this kit if you own a compatible 46-inch Cub Cadet or MTD tractor and want a solid aftermarket mulching blade set at a lower price than OEM—just verify your deck size and blade pattern first, and be comfortable with a moderate DIY install.
