|Three Harvestores, Stone Road near Branch, Wisconsin (1.19.2014)|
According to a USDA farm bulletin on homemade silos that predates the introduction of the Harvestore, the diameter of a silo "depends upon the quantity of silage to be fed daily." The Height is determined by the "number of tons of silage that will be required...governed by the length of the silage-feeding season." This farm with its three Harvestores and three concrete silos of varying sizes indicates expansions over time. Barns in various styles corroborate this as they coexist in the snow.
