Forge wagons have been around since 1891 when they were invented in Canada by William J. Conroy. However, the style of forge wagons we know and use today was invented in 1956 and used a steel or cast detachable chain for their operation. Since then forge wagon chains have been retrofitted with 600-series pintle chains, Steel Detachable Chain, and T-Bat/ T-Rod chain. Farmchains.com has in stock American Made steel pintle chains, steel detachable chains, as well as the standard T-Bar and T-Rod chains.
