If the mower cannot be identified through face or feature there would be no violation. Always use blurring tools whenever faces of people not aware and approving of being recorded might appear in our imagery.

People that record imagery of private and public property really need to spend some time learning about copyright law. Privacy is one thing, but ownership of likeness is pretty darn important too. An informed photographer will have release forms for people, events, property, and businesses signed and filed before placing imagery in the public domain, or in the hands of others that could/would publish their work. The way all the laws overlap make the task of legal compliance very difficult. Most drone folks unknowingly violate numerous laws on a regular basis, and leave themselves terribly exposed.
