What It Is

This 46" deck rebuild kit (model 918-0660) is a complete spindle, blade, and belt replacement set for Cub Cadet LT1045, LT1046, and i1046 lawn tractors. It includes three spindles (618-0660, 618-0625), three blades (177-2144, 742-0611, 942-0612), and a 122" drive belt (754-04153, 954-04153) for restoring cutting performance on a worn 46-inch deck.

Fitment & Compatibility

• Deck size: Only fits 46-inch decks. Measure your deck width before ordering.
• Models confirmed: Cub Cadet LT1045, LT1046, i1046. Also compatible with some RZT and Z-Force models using the same spindle setup, but verify your deck part number.
• OEM cross-reference: Spindles replace OEM 918-0660, 618-0660, 618-0625. Blades replace OEM 742-0611, 942-0612, 177-2144. Belt replaces OEM 754-04153, 954-04153.
• Check your existing spindles: If your deck uses a single-shaft spindle (older models), this kit won’t fit—it requires the three-spindle, two-belt configuration common on 2005-2010 LT series.
• Measure belt length: The included belt is 122" x 1/2". If your deck uses a different belt length (e.g., 120" or 124"), the kit won’t work.

Key Things to Know

• Quality vs OEM: Spindles are aftermarket but rated well (4.5/5). Blades are standard-duty—don’t expect heavy-gauge or mulching performance. Belt is reinforced but not Kevlar.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (spindle nuts: 30-35 ft-lbs), and a belt routing diagram. Plan 1-2 hours if you have basic mechanical skills.
• Common gotcha: The spindles may come without grease fittings. Pre-pack bearings with grease before installation to avoid premature failure. Also check blade bolt torque (50-60 ft-lbs) to prevent loosening.
• Deck removal recommended: It’s much easier to replace spindles and belt with the deck off the tractor. If you can’t remove the deck, expect a frustrating job.

Should You Buy It

Buy this kit if you have a Cub Cadet LT1045, LT1046, or i1046 with a worn-out 46-inch deck (noisy spindles, uneven cut, slipping belt) and want a cost-effective one-stop replacement. It’s not for heavy commercial use or decks needing high-lift or mulching blades—those require separate blades. For DIY homeowners, it’s a solid value at $96.50.
