8TEN Deck Spindle for Ariens & Gravely mowers — 6 7/8" OEM-fit replacement with hardware

The 8TEN deck spindle is a heavy-duty replacement spindle built to match OEM fit and function for specific Ariens and Gravely mower decks, restoring smooth blade rotation and deck stability.

If your mower’s deck is making noise, cutting unevenly, or showing visible play at the blades, a worn spindle is often the cause. The 8TEN Deck Spindle listed for Ariens and Gravely applications is sized and specified to replace the factory units referenced by part numbers 58810800, 59202600, 59215400, 59225700, and 69219700. It’s engineered to fit a wide range of models including Apex, Max-Zoom, Zoom, Zenith, Gravely Pro-Turn, ZT HD, Pro-Master, and Pro-Stance decks (note: it’s not intended for long-spindle deck versions).

How will this spindle restore my mower’s cutting performance?

Replacing a worn spindle eliminates blade wobble and uneven cutting patterns by returning the blade to its correct alignment and rotation. The 8TEN spindle includes the necessary blade-mounting hardware, so installation addresses both the bearing assembly and blade attachment points.

• Restores correct blade alignment for cleaner, more consistent cuts
• Reduces vibration and drivetrain stress caused by play in a worn spindle
• Includes blade mounting hardware for a more complete replacement
• Designed to match OEM dimensions for straightforward fitment
