What is stump jump plow?

The stump jump plow is an agricultural implement designed to efficiently cultivate land with uneven terrain, particularly in areas with stumps and rocks. Invented in the late 19th century, it features a unique hinged design that allows the plow blade to "jump" over obstacles rather than getting stuck. This innovation significantly improved farming productivity in regions where traditional plows would struggle, enabling farmers to till previously unusable land. Its design has influenced modern plowing techniques and equipment.
