Product Description

The TROY-BILT 918-04125c is a spindle assembly with integrated pulley, designed for use in the mower deck of Troy-Bilt lawn and garden equipment. The spindle assembly serves as the mounting and drive interface for the cutting blade, transferring power from the deck belt through the pulley to spin the blade at cutting speed. This component is a direct replacement part intended for installation by service technicians and knowledgeable equipment owners performing deck rebuilds or spindle replacements on Troy-Bilt outdoor power equipment.

This spindle assembly pulley is used in residential lawn mower deck applications. It is a common wear or damage replacement item serviced during seasonal maintenance, after blade strike impact, or when bearing failure causes deck vibration or noise. Installation is typically performed during deck removal and disassembly, making it a standard repair component for small engine equipment service shops and independent service dealers handling Troy-Bilt equipment.
