The origins of the A. B. Farquhar Company, founded by Arthur Briggs Farquhar (1838-1925), stretch back to the 1850s. Originally an employee (1856) and later a partner (1858) at the W.W. Dingee & Co. in York, Pennsylvania, Farquhar took over the company in 1862 after a devastating fire. The company became known as the Pennsylvania Agricultural Works. The company manufactured steam engines, sawmills, threshing machines, plows, agricultural steels, cultivators, grain drills, corn planters, horse powers, and other agricultural equipment.
A.B. Farquhar was later joined by his sons, William E. and Francis, and the company became A. B. Farquhar & Sons. In 1887, it was incorporated as the A. B. Farquhar Company, Limited. It began building threshing machines in 1887 and later produced cultivators.
When the company was acquired by the Oliver Corporation in 1952 it became the Farquhar Sawmill Division. Oliver sold the division to E. E. Titus Inc. of Petersburg, Virginia in 1956.
