There is a difference between being lazy or working smart. Lazy is not working. Working smart is just using tools to do the work that you would have to do otherwise. lol.
I agree with Keith tho, if you save 2 hours, then it is worth it. For example, if it takes you 15 minutes to hook up the trailer, load the mower at home, unload the mower when you get home again, and then unhook the trailer, then you still have 1 hour, 45 minutes saved. That is 1 hour, 45 minutes to mow other lawns or to..... be LAZY!!!!
