Heavy Mouldboard Plow

Timeline

1. 600–800Slavic and Germanic farming regions · BalticIn Northern Europe and along the Baltic coast, farmers improved plow structures by adding heavy plowshares and curved moldboards (moldboard plows), which could cut into heavy soil and turn clods over to one side, suited to damp lowlands. At this stage, ox traction still predominated.
2. 900–1100France and Flanders · FlandersThe heavy plow spread to France and Flanders under population pressure and the need to clear forests. Equipped with multiple shares, it could cut deeper furrows in a single pass, greatly improving reclamation efficiency and providing the arable base for subsequent crop rotation systems.
3. 1211–1500Core farming regions of medieval Europe · Central EuropeCombined with the horse collar harness, the heavy plow became the standard tillage tool of manorial agriculture in Northwestern and Central Germany. Peasants used it to plow fallow fields under rotation and forest margins; grain yields rose sharply, supporting the feudal urban economy and population recovery.
4. 1600–1800European farming regions · EuropeDifferent regions developed plow variants of varying weight and share count, adapted to local soil and draft-animal conditions. In the 19th century, steam- and internal-combustion-engine-drawn mechanical plows gradually replaced animal-drawn heavy plows, but the moldboard soil-turning principle still influences modern plow design.
