Of course you're not the only one. :laughing: It's a mental fatigue thing / combined with physical fatigue, depending on what you've been doing.
Just the other week I'd mowed the front area on the D110, say about 1.5 acres and the grass was 7-8" high. It took a couple of hours in afternoon 22c temperatures. At the very end I decided to mow an area that I bloody well knew had a ground watering hose and two power extension cords. Of course I'd be careful and spotted the hose... then promptly ran over/cut both of the extension cords. :duh:
Hey, I was tired.
