That's very true, it is labour intensive, I find bringing a radio helps a lot. Also I find myself working like a dog, trying to get it all done without taking breaks, lunch, etc and then getting home completely beat. My advice would be to bring snacks, water, radio, and take it easy. However I need to follow my own advice, lol. Mowing is nice alone becasue you are in and out fairly quickly, most of my properties are 20-30 minutes tops. I actually enjoy being solo, I have worked for a few large and small companies before starting on my own.
