Overview and metadata sections

Doylestown Agricultural Works in Bucks County, Pennsylvania produced farm machinery and ironwork that were sold around the world. For many years, it was the area's largest employer.

In 1849, Daniel Hulshizer and a partner moved to Doylestown and opened a small shop that made and sold threshers and horsepower engines. In 1867, Hulshizer expanded when he established the Doylestown Agricultural Works. The Doylestown Thresher, his best-known product, won first prize in its category at the Centennial Exposition of 1876.

By 1899, Doylestown Agricultural Works was manufacturing and selling diverse agricultural machinery, including seed sowers and planters, plows, cultivators, and mowing and reaping machines. In the early 1900s, other types of metal products were also produced out of the works, including automobiles (under the name Winslow Motor Carriage Company), park benches, and wrought iron grill work. The company opened an export office in New York City to handle overseas sales.

In 1920, General Motors bought the majority of Doylestown Agricultural Company stock and put it under its Sampson Tractor Division in an attempt to compete with Ford Motor Company in the agricultural machinery market. Doylestown Agricultural Company bought back its own stock in 1921.

In 1937, due to the Great Depression, Doylestown Agricultural Company ceased producing new machinery. It continued to sell and repair agricultural equipment until 1968, when it closed completely. A historic marker from the Pennsylvania Historical and Museum Commission was erected on the site in 2003.
