Timemaster Sync Belt Replacement

How to replace the synchronous belt on a Toro Timemaster. This is the belt that synchronizes the two blades to cut together. If the belt breaks while in use, make sure to inspect the blades as they may sustain damage warranting replacement in addition to the belt.

The official Toro part number for this belt is 120-3335, however the belt used in this video was a Stens 265-610. I went with the Stens because my local Toro dealer was out of the genuine Toro part and only the Stens was availible for Amazon Prime shipping so I could get mower back in service faster. I plan to keep a genuine Toro belt on hand in the future now just in case I need it. It appears that the sister Exmark Commercial 30" and Toro Turfmaster mowers likely uses the same belt and process, but I cannot confirm this.
