Agricultural & General Engineers Limited (AGE) was a holding company formed on 4 June 1919 during a postwar economic "boom" to combine five British engineering companies: Aveling & Porter, E H Bentall, Blackstone, Richard Garrett and J & F Howard. The holding company's business was described to the judge considering its 1932 winding up as: "agricultural, transport, road, constructional and general engineers".

Aveling and Porter was a British agricultural engine and steamroller manufacturer. Thomas Aveling and Richard Thomas Porter entered into partnership in 1862, and developed a steam engine three years later in 1865. By the early 1900s, the company had become the largest manufacturer of steamrollers in the world. The company used a rampant horse as its logo derived from the White Horse of Kent.
