The deck belt on this 2021 zero turn vibrated so badly it shook the entire mower. Really a bad design. The span the deck belt traveled should have a tensioner mid ways but didn't so I added one. This helped tremendously but still has the issue on the opposite side. I'll address that later. This pulley runs smooth and the height allows the deck belt to move up/down with the adjustable deck height.
