Overview

Excerpt from Morton's Handbooks of the Farm, Vol. 6: Equipment Drainage Implements. - A draining plough for steam power* consists of a vertical coulter carrying a horizontal mole suspended from the beam frame of a four-wheeled carriage. It is hauled by wire rope from the winding drum of a steam engine, and the mole is raised or lowered by screw gear as it travels, according to the unevenness of the surface. When used as a mole plough two pits are first dug, one at each headland: the coulter is then lowered into the one and hauled to the other, the mole leaving an open waterway behind. When pipes are used, pits are dug at intervals: a wire rope is hooked on to the heel of the mole, and pipes strung on it are drawn through the distance between two pits; the wire rope is withdrawn, leaving the pipes behind, and another length of pipes is strung on. Depth 2 to 3 feet. For very steep inclines, and in subsoils liable to wash away, mole drains are unsuitable.
