My wife is a heck of a worker. The Queen Bee is the ultimate worker bee too. When we are doing a task that both of us can jump into, she is usually driving the tractor. So she could take loads up to the dumpsite, less than 1000 yds away, and when she is working that out I could be doing prep.....There is lots to do, besides just shoveling raw dirt. I think it would be very efficient in comparison to working by myself. Probably more than twice the amount of work could be done. As it is, I am either moving the soil across the road or I am piling it behind me. I could just put most of it in the dump trailer...and while she was taking it up to dump, I could work and fill the downs slope....move debris off the area I was going to work. I don't think I could keep up with her.
