An excavating device is disclosed which is capable of attachment to a conventional hydraulic boom structure having a power-driven winch cable. The device has a bucket pivotably mounted thereon, such that when the device is attached to the boom structure in a first mode, the bucket can be driven by the winch cable as a shovel and when attached to the boom structure in a second mode, the bucket can be driven by the winch cable as a back hoe.
