I have a mini digger hired for this weekend to level some of my backgarden and to level / set founds for a garage. The garden is sloped and quite uneven. The fella is charging £85 a day without a driver or £150 with a driver. The area to be leveled is about 30m * 10m. Has anyone driven these diggers before and are they simple enough to use? Basically if it is a hard job I will get the driver as he will probably be a lot quicker than me and if he can do it in one day it would make sense. I am worried that it'll tip over and have heard a few horror stories> Anyone any thoughts?
