Our lawn is too small for a riding lawnmower to be honest.
Doesn't stop our neighbor with an even smaller yard from using the riding lawnmower and also mowing into our yard and actually destroying our grass.
Seriously I've mowed the property line like... twenty times, and each time he ignores it and mows his own way.
The funny thing is, the way he's mowing, he's actually screwing himself out of valuable back yard space.
Try land mines.
We want to save our yard, not destroy it.
We're hoping that putting in trees or bushes along the property line will help.
Unfortunately, one thing we've figured out is that he has connections. He consistently parks in front of the fire hydrant, we've even seen officials go through (including one time it was inconvenient when they were emptying and filling the fire hydrant for reasons I don't fully understand) and the guy has never received a ticket for it. So he's got some connections in the police force.
He and all of his friends also drive huge trucks and he tends to find any excuse to hang a flag in his front porch, so I'm guessing he's a highly conservative redneck.
