Deck Spindle Assembly Replaces 918-06977 Fits for MTD Cub Cadet 46 inch Deck XT1-LT46 XT2-LX46 KH KW FAB Mower 918-06977A 2 Pack

What It Is

This deck spindle assembly is the rotating hub that drives the mower blade. It replaces OEM part 918-06977 and is designed for MTD and Cub Cadet zero-turn and lawn tractors with a 46-inch fabricated (FAB) deck, specifically models like the XT1-LT46 and XT2-LX46.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch fabricated steel deck (not stamped steel). Check your model number: this fits Cub Cadet XT1-LT46, XT2-LX46, and similar KH/KW series. It also works on some MTD and Troy-Bilt models with the same deck. Measure the existing spindle housing: this assembly uses a 5/8-inch output shaft and a 3-inch diameter pulley. It’s a direct OEM replacement for 918-06977 and 918-06977A. Verify blade bolt pattern (usually 5-point star) and spindle mounting hole spacing (typically 3.25 inches center-to-center). If your deck uses a different pulley size or shaft diameter, this won’t fit.

Key Things to Know

• Quality vs OEM: This aftermarket 2-pack is generally well-reviewed (4.5 stars), but some users report bearings lasting 1-2 seasons under heavy use. OEM Cub Cadet spindles often last longer but cost 2-3x more.
• Installation difficulty: Moderate. You’ll need a socket set, breaker bar, and possibly a puller to remove the old spindle from the deck. Expect 30-60 minutes per spindle.
• Common gotchas: The included bolts may be slightly different thread pitch than OEM—check yours before tightening. Also, lubricate the bearing housing with grease before installation; many failures come from dry bearings.
• Deck removal required: You’ll need to remove the mower deck to access the spindle bolts. Have a jack or blocks handy.

Should You Buy It

If you have a 46-inch fabricated deck Cub Cadet or MTD and need a budget-friendly replacement for worn spindles, this 2-pack offers good value for DIY maintenance. It’s not for commercial use or high-hour mowing—bearings may wear faster than OEM—but for residential lawns, it’s a solid, cost-effective fix.
