Are you in a dearth? Lack of nectar can make them cranky, and if you have recently removed honey they will stay aggressive for a few days.
I almost always get one or two guard bees that become very defensive for a few days after inspections, which is why I wore my veil down to feed my package today, I'd been in both hives and did a complete inspection on the big one. Sure enough, had a single bee banging me in the veil repeatedly. I usually end up smashing that one or two that get aggressive, they usually ignore me.
Blowing mower discharge directly into the hive is going to get you stung, and while I don't have a problem with my mower, when my neighbor used is large mower on my back yard last year the bees came pouring out, must have been the sound or vibration that is different.
I would rotate the hive so that you not so very cooperative neighbor cannot blow grass clippings into the entrance, and I also recommend using a hive stand tall enough to prevent it under any circumstances. If that doesn't work, I would move the hive away from his properly as far as I could. If he still gets stung, I would move the hive off the properly, not worth the hassle or potential for lawsuits, however unfounded.
