46 Inch Mower Deck Rebuild Kit Fit for Cub Cadet XT1 LT46 XT2 LX46 Craftsman T225 T240 T2800 T3100 T8600 Parts Spindle 918-06977 Blade 942-04244A

What It Is

This 46-inch mower deck rebuild kit includes three spindles (OEM #918-06977) and three blades (OEM #942-04244A) to replace worn-out cutting components on select Cub Cadet, Craftsman, and Troy-Bilt lawn tractors. It’s designed for a complete deck overhaul, restoring cutting performance and reducing vibration.

Fitment & Compatibility

• Deck size: Only fits 46-inch stamped or fabricated decks. Measure your deck width to confirm.
• Models: Cub Cadet XT1 LT46, XT2 LX46; Craftsman T225, T240, T2800, T3100, T8600. Also fits some Troy-Bilt and MTD models with the same spindle pattern.
• OEM cross-references: Spindle 918-06977A, 918-06977; Blade 942-04244, 942-04424, 742-04244.
• Check before buying: Verify spindle bolt pattern (typically 3-bolt, 3.5-inch spacing). Measure blade length (should be 15.5 inches) and center hole diameter (usually 1 inch). Ensure your deck uses a standard 3-spindle system—not a 2-spindle or offset design.

Key Things to Know

• Quality: Aftermarket kit, not OEM Cub Cadet. Spindles are often zinc-plated steel with sealed bearings; blades are hardened steel. Expect decent durability for residential use, but OEM parts may last longer under heavy commercial use.
• Installation difficulty: Moderate. Requires removing the deck, unbolting old spindles (may need penetrating oil for rusted bolts), and reassembling. Plan 1–2 hours with basic hand tools.
• Common gotchas: Spindle bolts may be reverse-threaded on some models—check your manual. Blade orientation matters: the cutting edge must face the direction of rotation. Torque spindle bolts to 35–45 ft-lbs; overtightening can warp bearings.
• Missing hardware: Kit includes spindles and blades only. You may need new lock washers, blade bolts, or spindle pulleys separately if yours are worn.

Should You Buy It

This kit is a cost-effective choice for DIY homeowners with a 46-inch Cub Cadet or Craftsman tractor who want to replace all three spindles and blades at once. It’s not for commercial use or for those needing exact OEM fit. If your deck has significant rust or bent pulleys, you’ll need additional parts—but for a straightforward rebuild, it’s a solid value at $83.
