Bomusou 46" Deck Spindle Rebuild Kit for Cub Cadet LT1045 LT1046 – 3 Spindles, 3 Blades & 122" Belt

Bomusou's 46" deck spindle rebuild kit replaces all three spindles, three blades and the drive belt to restore cutting performance on compatible Cub Cadet LT1045 and LT1046 mowers. This comprehensive kit contains three complete spindle assemblies, three mower blades (two outer, one center) and a full-length deck belt engineered to match factory fitments. Each component is sized to work with common Cub Cadet/MTD part numbers listed by the manufacturer, making this a practical choice when you want a coordinated rebuild rather than piecing parts together from multiple sources.

The kit is built for straightforward installation on 46-inch decks from specific Cub Cadet LT1045 and LT1046 models (2008 and newer) and compatible MTD/Bolens machines. The spindles have factory-style mounting and pulley diameters, the blades are matched in lengths and cutting profiles, and the belt follows the original cross-section for tension and tracking. Check your mower's model and part numbers to confirm compatibility before purchasing.

What exactly is included in the kit and why it matters?

This package supplies three complete spindle assemblies, three blades (two longer outer blades and one shorter center blade) and one deck belt sized 122" x 1/2". These parts replace the deck’s most wear-prone items, allowing you to correct vibration, poor cut quality, or slipping belts without multiple orders.

• 3 spindles: 6-3/4" height, 4-5/8" mounting bolt spacing, 5-5/8" pulley OD
• Outer blades: 16-1/4" length, factory-style fitment references
• Center blade: 14-13/16" length, matched center profile
• Deck belt: 122" long by 1/2" wide, OEM cross-section replacement

How do these parts compare to original equipment (OEM)?

The spindles and blades are manufactured to replicate OEM dimensions and mounting patterns so they bolt in using existing hardware. Pulley diameter and bolt spacing match the common Cub Cadet/MTD specifications, helping preserve belt alignment and blade tip speed similar to original operation.

• Spindle dimensions mirror OEM specs for direct replacement
• Blade lengths and hole patterns follow factory standards
• Belt size and profile match recommended OEM length and width

How difficult is installation and what tools are needed?

Installation requires basic mechanic skills and common yard-tractor tools: wrenches, sockets, torque wrench, and blade removal equipment. Replacing all three spindles and blades involves lifting the deck or flipping the mower, so take safety precautions and follow torque specs where applicable.

• Tools: socket set, torque wrench, blade holder or strap wrench
• Estimated time: 1.5–3 hours for a DIYer with basic experience
• Safety: disconnect spark plug, secure mower before work

Will this kit fit my Cub Cadet LT1045 or LT1046 model?

The kit lists compatibility with LT1045 (2008 and newer serial prefixes shown) and LT1046 models and references many OEM part numbers for cross-checking. To verify fit, compare your mower’s model/serial numbers and existing part numbers against the references provided in the product details.

• Compatible with LT1045, LT1046 and many MTD/Bolens decks
• Cross-referenced part numbers included for confirmation
• Always compare your current spindle/blade/belt numbers before ordering

Who is this for: This Bomusou kit is aimed at homeowners and small-farm users who want a complete, coordinated deck refresh for a 46" Cub Cadet LT1045 or LT1046 mower. It's ideal when vibration, dull cutting, or belt slipping indicate multiple worn deck components — giving you spindles, blades and belt in a single purchase to get the deck back to even cutting performance.
