Which John Deere models and deck sizes will this spindle work with?

This replacement is designed for a wide range of John Deere residential and commercial lawn tractors and zero-turn mowers, and supports common 42" and 48" deck configurations. Check your machine’s part number or measure spindle mounting pattern to confirm compatibility before ordering.

How easy is installation and what hardware is included?

The spindle arrives as a complete assembly with the main fasteners and components needed for a typical swap, so installation is usually straightforward for anyone comfortable with deck disassembly. Threaded mounting holes and included bolts mean you don’t need to reuse worn fasteners, and the star-shaped blade mount keeps blade alignment consistent.

• Includes 8 tapped mounting bolts (four per spindle) to match threaded deck holes.
• Comes with 2 blade nuts, 2 pulley lock nuts, and a grease fitting pre-installed.
• 7-point star blade mount for secure blade seating and easy alignment.
• Overall height 7" (177 mm) and OD 5" (127 mm) for fit verification.

What maintenance does the pre-greased spindle require?

The spindle ships pre-greased for initial use but should be properly serviced before and during the mowing season to ensure long life. Regular greasing through the supplied fitting and periodic oil changes at season end help prevent premature wear and protect bearings.

• Grease through the side fitting until grease appears at the base weep hole.
• Top up grease periodically during heavy use or long mowing seasons.
• Drain and replace oil at the end of the season for optimal longevity.
• Inspect for play or unusual noise and re-torque mounting bolts after initial run-in.

What comes with the warranty and after-sales support?

ZALANA includes a 6-month warranty and customer support for questions about fit or installation. If you encounter issues or need part verification, contact the seller via email for assistance and resolution options.

• 6-month limited warranty from ZALANA covering material and workmanship.
• Package contents clearly listed: 2 spindle assemblies, 8 tapped bolts, 2 blade nuts, 2 pulley nuts.
