Building upon its original Shark Chain, Ditch Witch introduces the Shark Chain II, a digging chain with a new design for improved trench cleaning. A rounded top plate is included to allow optimal placement of the cutting teeth, while the addition of a rounded cleaning shoe on the back of every other digging station helps enhance trench clear out. These features also help create a curved bottom to the trench that cradles the pipe or other services being installed. Additional features are larger chain rollers and a raised rivet design on the sidebar. The Charles Machine Works Inc., Card No. 307
