When I turned the blades on on my Snapper Pro, the whole mower shook and made a lot of noise. Upon inspection, one of the blades appears to be free-spinning instead of connected to the belt.
As you can see in this video, the blade is wobbly and spins freely. When I try to move the other blades, they don't move, but I can see the belt wiggle, showing that they're connected.
My first guess is that I need to somehow tighten that bolt under the blade, but upon inspection, it doesn't seem loose at all. I haven't taken a wrench to it yet, but I assumed if it was loose enough to allow that much play in the blade, that it would be loose to the touch too.
Thoughts on what I should do or try?
Here's another video of me fiddling around with it and showing that when I attempt to spin a different blade, it does wiggle the bolt and housing above and below the loose blade.
