The Dennis Motor Mower was produced from the 1920s onwards. This example, seen at Malvern Autumn Show in 2009, was made in 1924. Early Dennis machines can be identified from their square petrol tank (later models had round tanks) but otherwise outwardly look the same as older designs. On the video look out for the way the grass is emptied from the box by rotating it on the mounting arms at the front.
