A method for displacing bees from vegetation subject to cutting by a mowing machine having a cutting deck and using a blower assembly affixed to the mowing machine. The assembly is provided as a fan or motorized blower affixed to a funnel. In operation, the fan or motorized blower creates then forces a concentrated air stream into the funnel that then directs the concentrated air stream to an area of vegetation immediately in front of the cutting deck, displacing bees in the area of vegetation prior to cutting. A funnel mouth is oriented so that the emitted air stream is at least as wide as the cutting deck, and multiple blower assemblies or larger funnel attachments may be used to accommodate larger cutting decks. The method includes selective actuation of the blower while operating the mowing machine.
