The amount will depend a great deal on the area, and on the size of the equipment. I would think that a medium (Cat 320 size) excavator and operator should probably go for around $60 per hour, or around $400 per day. This is based on what I have seen around here. This price might shock at first, but you really have to see it to apreciate the amount of work that a skilled operator can do with one of these machines in a day. Also gotta consider that the maintenance on these things, as well as a truck a trailer big enough to haul one does not come cheap. I think that most of the guys around here also have a minumum charge to help to cover the time it takes to transport one of these beasts around.
