A range of mowers made by Barford & Perkins, late 19th to early 20th century. It was on these machines that the manufacturers first (1902) placed the Wansbrough Patent method of altering the height of cut. Introduced in 1886, by 1890 these chain-driven roller mowers were available in sizes from 8 to 21 inches at prices ranging from £2.10.0d to £9.0.0d. Larger 24 and 27 inch machines were sold for donkey or pony haulage.
