A home-made tree digger/root cutter. Assembled from parts ranging from the 1930s (the wood spoked wheels) to 1948 (Chevy truck parts), the seven-ton behemoth was once used in a pecan orchard in Las Cruces. Two water heater tanks on either side of the engine were filled with dirt, serving as ballast. "This is very reflective of the self-sufficiency, the ingenuity of the farmer," Laumbach says. "They just made do with what they had."
