  • Patent number: 4461458
    Abstract: A shovel or spade for digging and lifting with minimal effort by the user reacts against the ground during use through a flat foot plate having a forward end cleat which penetrates the ground to resist rearward displacement of the foot plate. The foot plate near its forward end is connected to the shovel or spade handle shaft near and above the blade of the tool by a rigid link whose opposite ends are pivotally connected with the foot plate and handle shaft on parallel pivot axes across the foot plate and across the axis of the handle shaft. The tool can be operated substantially in a walking mode by the application of downward pressure on the handle shaft.
