Old lawn mowers are featured in Britain's Greatest Machines on the National Geographic channel in the UK (available on Sky and Virgin) on Saturday 20 February at 9pm. The show is presented by Chris Barrie (Rimmer the hologram in Red Dwarf) and features machines from a different decade each week. This week it's the 1920s and the show includes Chris trying out an Atco Standard. That's all we know but if you wanted to choose one mower from the 1920s it would have to be the Standard. You can see more about the show, with still images and a short preview video at the link below.
