I don’t think the hub of the fan was pulled over to make those grazes, I think it’s more likely those happened when blades broke off or something went into the fan and was dragged over the transmission case.
As for running without, that fan is partly there for direct cooling, partly to keep grass clippings from collecting on top. Even in cooler temps, a blanket of clippings could make it get hotter than it should be.
This isn’t a science related meme. I can understand you not being sure where to put it, I haven’t seen a “Racist Memes” community on Lemmy.
This may be the most apt application of this meme I have ever seen, lol
That is a another good concept, but that is exactly not what this study was about, haha! This study was about using land that had been farmland for solar and restoring the natural plant life of the area. This increased the insect population dramatically, including many pollinator species, so using less productive fields for solar/natural habitat instead could further increase the yields of better fields in the area.
It probably happened when the tensioner failed and the belt flew off.
