Miško, read my post more carefully, you'll see what the whole topic is about.
and yes, you can mow the lawn around your bee house without problems, because the mass of the whole structure pressing onto the foundations is killing the vibrations, well actually the mass is too big to be disturbed by little vibrations a lawn mower causes. but, when you have only 1 hive on one concrete block, vibration transmision must be enormous.
