An excavating machine includes a main frame, an endless digging chain, and a boom. The boom is mounted to the main frame and is adapted to carry the digging chain. The boom includes an upper surface, a lower surface, an inner end and outer end. The surfaces are adapted to slidably engage the chain. A drive sprocket is mounted to the main frame and is disposed at the inner end of the boom for engaging the chain. A wear plate is mounted to the boom and is disposed between the drive sprocket and the inner end of the boom for slidably engaging the chain between the drive sprocket and the upper surface of the boom inner end.

A method for pipeline padding for reducing the size of spoil disposed in a pile utilizes a vehicle having first and second sides adapted for movement on the surface of the spoil pile. The vehicle includes first and second surface engaging devices disposed on each side of the vehicle. The spoil is crushed using a crushing assembly connected to the vehicle for movement with the vehicle. Spoil is transferred using a transferring assembly connected to the vehicle for movement with the vehicle for transferring spoil from the pile to the crushing assembly. Disposed between the vehicle sides, adjacent the transferring assembly and connected to the vehicle for movement with the vehicle is a control structure for controlling passage of spoil from the spoil pile forward of the surface engaging devices to a position under the surface engaging devices.
