I have my colonies spaced so the lawn tractor fits between them. Drive thru twice, once each way so I can trim right up to the stand on each side, and leave next to nothing left to clean up with the trimmer. Mowed the yard 5 or 6 times now, just finished about an hour ago. I've never been bothered by the bees while mowing, except the occaisional one coming home fast that bumps into me on the way by. Haven't been stung while mowing yet.
