8TEN Deck Spindle for John Deere X300 X300R X304 X310 X324 Z225 Z245 - 2-Pack with Hardware & Grease Fittings

8TEN replacement deck spindles (2-pack) restore cutting performance for compatible John Deere X300-series tractors and Z-turn mowers with OEM fit and included mounting hardware.

These 8TEN deck spindles are engineered as direct-fit replacements for John Deere part numbers AM136733, AM143469, and AM134292. Built to the same mounting pattern and height specifications as the originals, the spindles arrive as a two-pack with grease fittings and blade mounting hardware included so you can install both units and get your mower deck back to reliable operation.

Will these spindles fit my John Deere model?

Yes — the 8TEN spindles match the OEM fit for a range of John Deere lawn and garden tractors and zero-turn mowers. Confirm compatibility by checking your tractor’s parts list or the OEM part number on your existing spindle.

• Compatible OEM numbers: AM136733, AM143469, AM134292
• Fits John Deere X300, X300R, X304, X310, X324 Select Series
• Also fits John Deere Z225 and Z245 EZtrak zero-turn mowers

How do these spindles compare to the original parts?

8TEN spindles are manufactured to match the original dimensions and mounting points so replacement is straightforward. They come with grease fittings and blade mounting hardware included, ensuring immediate compatibility and maintenance access.

• Height: 6.38 inches to match OEM specification
• Includes grease fitting for routine lubrication
• Hardware included: yes — blade mounting bolts/nuts supplied
• Pulleys are not included, so reuse the original pulley or order separately

What should I know about installation and maintenance?

Installation follows the OEM mounting pattern and typically requires basic hand tools and standard torque specifications from the tractor manual. Greasing the spindle after installation and at regular intervals will extend bearing life and keep cutting performance consistent.

• Use manufacturer's torque specs when securing spindle to deck
• Grease through the included fitting until grease purges seals
• Retain original pulley or replace separately if worn
• Inspect blade mounting hardware and balance blades when reattaching

What does this two-pack offer for cost and downtime?

Buying spindles in a two-pack reduces per-unit cost and lets you replace matching spindles together, which helps maintain even deck height and cutting quality. Having both replacements on hand minimizes mower downtime and avoids a second service visit.

• Two spindles included for matched replacement across the deck
• Hardware included so fewer trips to the parts store
• Saves time by replacing both worn spindles at once
• Good option for seasonal maintenance or pre-sale prepping

Who is this for: Homeowners and landscapers who maintain John Deere X300-series tractors or Z220/Z245 EZtrak mowers and need a reliable, OEM-spec spindle replacement with included mounting hardware and grease fittings. Choose the 8TEN two-pack if you want like-for-like dimensions (6.38" height and 7-point star blade pattern), straightforward installation, and minimized downtime for your deck maintenance.
