ATRACYPART Mower Deck Spindle for Exmark Lazer Z 48–72in Decks — 7.5" Height, Heavy-Duty Steel

ATRACYPART 109-6917 is a direct-replacement mower deck spindle engineered to restore smooth blade rotation on Exmark Lazer Z series zero-turn mowers with 48"–72" decks.

When a worn or damaged spindle causes vibration, noise, or uneven cutting, replacing it with a properly sized, heavy-duty unit brings your deck back to stable operation. This spindle (also referenced as 109-2102, 109-0764, 810CSP2287N) matches the factory mounting pattern and overall height to fit many Lazer Z AS, DS, XS and X-series models. It’s precision machined from high-strength steel to resist wear and maintain alignment under load, helping blades cut cleaner and reducing downtime for repairs.

Which Exmark models and deck sizes will this spindle fit?

This spindle is compatible with a broad selection of Exmark Lazer Z machines across several series. Check your model code and deck width against the list below to confirm fit before ordering.

• Lazer Z AS: LZAS29KA604LP (60" and 72" decks)
• Lazer Z DS: LZDS902K605 (60"), LZDS902K725 (72")

What are the spindle’s key dimensions and mounting details?

Knowing the spindle height and hole spacing avoids ordering the wrong part. This unit matches common Exmark deck geometry so it aligns with blades and pulleys when installed.

• Overall height: 7 1/2" (191.5 mm)
• Mounting hole center-to-center distance: 6 1/2" (165 mm)
• Replaces OEM numbers: 109-6917, 109-2102, 109-0764, 810CSP2287N

How does this spindle improve cutting performance and durability?

Better spindle alignment reduces blade wobble and vibration, which directly affects cut quality and component life. This spindle’s materials and machining are chosen to hold tolerances under heavy use, helping blades maintain a steady rotation and produce a more uniform finish.

• Precision-machined shaft for smoother blade rotation
• High-strength steel construction for wear and corrosion resistance
• Reduces vibration to extend blade, belt, and bearing life
• Helps maintain even cut patterns across the deck

Is installation straightforward and what should I prepare?

Installation is designed to be user-friendly for owners comfortable with basic mower maintenance. The spindle uses the same mounting footprint as the referenced OEM parts, which simplifies swap-out when bearings, blades, or pulleys are already removed.

• Requires common hand tools and basic mechanical skills
• Swap bearings, seals, and pulleys as needed during service
• Verify deck alignment and belt routing after installation
• Allow time to torque fasteners to manufacturer specs

Who is this for? Lawn care professionals, property managers, and DIY owners who operate Exmark Lazer Z AS/DS/XS/X-series zero-turn mowers and need a reliable replacement spindle will benefit most. Choose this ATRACYPART spindle when you want a precisely machined, heavy-duty replacement that matches OEM geometry and restores cutting performance across 48"–72" decks.
