Did you know that your grass is 80% water? That is why it is always best to cut your grass on a higher setting because this will insure your lawn not turning brown as fast as it would if it was cut shorter. Many people are tempted to cut the grass at 3 inches when in fact you should only take about an inch off the top. Grass is like a hair cut the difference between a good lawn cutting and a bad lawn cutting is two weeks!
I had a 2 minibarns moved. First one: First we jacekd it up and put it on blocks. Then we backed a trailer under it and moved it across the yard. Then we placed it back on the blocks. Second One. We actually moved it across town. But it was a few years ago. I called an excavator. He used one of his heavy equipment tractors, I think a backhoe with forks and just raised it up and carried it down the road. Both jobs were done with no damage to the buildings. Good Luck.
