Mechanical Thinning

Anyone who mountain bikes is likely familiar with the term, mechanical transportation and the claim that it is distinct from motorized forms of travel. Presumably then other activities in the forest should follow the same logic.  So when I heard the phrase, mechanical thinning I assumed it must be some type of non motorized logging.  So I did some googling. Guess which image came up.

Can we stop pretending that in common parlance mechanical means heavy machinery, not bikes?
