Product Description

The TROY-BILT 783-06643-0637 is an idler support bracket designed for use in the drive and blade engagement systems found on Troy-Bilt lawn and garden equipment. This structural component holds the idler pulley assembly in proper alignment, maintaining correct belt tension across the mower deck or drive system. It is a direct OEM replacement part intended for installation by equipment technicians and experienced outdoor power equipment service professionals.
