Troy-bilt 956-0449 Sheave

Product Description

The TROY-BILT 956-0449 is a sheave designed for use in Troy-Bilt lawn and garden equipment. A sheave is a grooved pulley wheel that guides and redirects drive belts within a power transmission system. This component plays a direct role in transferring engine power to cutting decks, augers, or other driven assemblies depending on the host machine. Replacement is typically needed when the original sheave shows signs of wear, cracking, or belt slippage that cannot be corrected by belt adjustment alone. Installation is performed by qualified equipment technicians or experienced service personnel familiar with outdoor power equipment drivetrains.

This sheave is a replacement part for Troy-Bilt lawn and garden equipment. Typical applications include walk-behind mowers, riding mowers, and related outdoor power equipment that rely on belt-driven power transmission systems. It is suited for both professional service shops and experienced owner-technicians performing drivetrain maintenance or repair.
