What are the key specifications and physical details?

This spindle has been machined to match the original part’s critical dimensions so blade height and deck geometry remain unchanged. Knowing these dimensions helps verify compatibility before installation.

• Overall height: 6 9/16 inches for correct blade-to-deck clearance.
• Shaft profile: round 5/8" (0.625") diameter for bearing and pulley fitment.
• Mounting pattern: 4 spindle mounting holes for direct bolt-up replacement.
• Comes with blade mounting hardware included to simplify reassembly.

How does installation and fitment look on the mower deck?

The unit is made to bolt directly into the existing mounting points using the same hole pattern and shaft diameter as the OEM part, minimizing additional adjustments. Typical installation requires removal of the deck and old spindle, followed by torqueing the spindle to spec and reattaching the blade and belt components.

• Direct bolt-on design reduces modification or machining needs.
• Includes blade mounting hardware so you can finish assembly without extra parts.
• Maintain original belt alignment and pulley spacing when installed to spec.

What should I expect for durability and performance?

Constructed to meet the demands of regular mowing, this spindle is built from durable materials and precision-machined surfaces to resist wear and maintain blade tracking. Proper installation and routine maintenance (bearing checks, torque inspections) prolong service life and keep the deck cutting true.

• Robust construction intended for frequent outdoor use and deck loads.
• Precision shaft sizing reduces wobble and uneven blade wear.
• Replace worn spindles to prevent belt slippage, poor cut quality, and unsafe blade movement.
