This one is pretty simple, I have a customer that wants me to regrade his entire property, about 50 yards worth of dirt. Will be using a CAT 259 skid loader, how many hours are we looking at to move through that pile and spread it out?? Easy access to the dirt, won't be traveling more than a 100feet from the pile and most of it will done near where the pile will be dropped at. Never worked with that much dirt at one time, just need some ballpark estimates. TIA.
