One of the mower manufacturers who made improvements upon Budding's original design (see also Shanks and Samuelson), Thomas Green designed a lighter machine in 1855; his design winning the first lawn mower trial which took place at Chiswick in 1858. In that year Ransomes stopped producing Budding mowers and became retailers for both Greens and Shanks. In 1859 Green's were to produce the world's first chain-driven mower, the "Silens Messor" which was to remain in production until 1935. They continued to produce a wide range of mowers until the mower side of the firm was acquired by Hawker Siddeley in the 1960s and finally closed down. The Green name and designs were taken over by Reekie of Arbroath.
