Similar - couple of neighbors of mine enjoy the leaf blowing and riding mowers. I mean... it's not speculation, one said "oh, i love it - it's my relaxation time". And... when he can, he'll spend 2-3 hrs putzing around riding and blowing whatever he can. We have the same size yard, and have a company which is paid by the job. They can do the whole same size in about under 30 minutes (often just with 1 person - 2 folks it's often 20 minutes).

There's little we can do when someone gets pleasure out of running a loud motor for hours at a time. He started a leaf blower, then left it running next to our window while he went inside for about 10 minutes (bathroom visit probably?). Just... insanity.
