Toro 138-6058 Blade Drive Sheave 6.50 Inch

Product Description

The TORO 138-6058 is a blade drive sheave designed for use in the belt-driven blade engagement systems found on Toro lawn and turf equipment. The sheave measures 6.50 inches in diameter and serves as the pulley component that transfers rotational power from the drive belt to the cutting deck blade spindles. Proper sheave condition is critical to maintaining correct belt tension, reducing slip, and ensuring consistent blade tip speed. This part is installed by qualified equipment technicians and landscape equipment service professionals.

This blade drive sheave is suited for residential and commercial Toro mowing equipment that uses a belt-and-pulley blade drive configuration. It is a direct replacement component intended for use during scheduled drivetrain maintenance or when the original sheave shows signs of wear, cracking, or groove damage that causes belt slippage or premature belt failure. Refer to your equipment service manual to confirm fitment before installation.
