Abstract
An excavator with a wireless controlled hopper-spreader allows a single operator to strip off topsoil and spread the stripped off soil more or less evenly after a mineable substance such as gravel is removed. The hopper-spreader uses about a fifty foot conveyor and may be totally operated by an operator in the excavator cab. This combination may be both faster and cheaper than a normal dragline operation.
