A 20th century ball-bearing sidewheel mower made by The Eclipse Lawn Mower Co. of Prophetstown, Illinois, USA. This was made in various cutting widths and cylinder variations, but all (apart from export-only machines) had the firm's Adams self-sharpening device. Local collectors in the US give the manufacturing dates of the "Lady" as 1908-1928. An export-only model, occasionally to be found in the UK, utilised the frame of the post-war "Arlington", wheels from the Model "M", and married these to pre-war "Lady" handles. One example of this export mower in an Essex collection has a light green colour scheme.
