A Stowmarket firm started in 1920 by L.J. Tibbenham. In 1925 the company added lawn mowers to their range of products. These were sidewheel machines made under the Suffolk name and those of retailers such as Selfridges. In 1954 the popular "Colt" and "Punch" powered roller mowers were introduced. In 1958 the company became part of the Qualcast Group, and in 1967 this Group (by then including ATCO) merged with Birmid Industries to become Birmid Qualcast. Suffolk amalgamated with ATCO in 1969 to become Suffolk Lawn Mowers, all production then moving to Stowmarket. Birmid Qualcast were acquired by Blue Circle Industries in 1988 and in 1992 there was a further name change to Atco-Qualcast.
