The Toro 110-0726 Lawn Mower Spindle Shaft supports smooth blade rotation and proper cutting performance during mowing. Installed within the spindle assembly, the shaft provides the central support for the blade and related rotating components while transferring motion through the mower’s drive system. Proper shaft alignment helps maintain balanced blade movement and can reduce unwanted vibration during operation. This replacement part is a practical solution for a bent, worn, or damaged spindle shaft that may cause blade wobble, noise, or uneven cutting. Replacing the shaft can help restore normal spindle function and support reliable mower operation during routine lawn maintenance.
