Product Description
The TORO 1-603805 is an OEM-style idler pulley designed for use in Toro lawn and garden equipment drive systems. Idler pulleys serve as tension and routing components in belt-driven systems, maintaining proper belt engagement across the drivetrain. This part is installed by equipment technicians and experienced service professionals performing belt system maintenance or replacement on applicable Toro units.

This idler pulley is used in Toro lawn and garden equipment where belt-driven systems are employed for blade engagement, traction drives, or other power transfer applications. It is suited for residential and light commercial equipment serviced by small engine repair technicians and outdoor power equipment dealers. Refer to the applicable Toro parts manual for the specific unit to confirm this pulley is the correct fitment before installation.
