43 - The Fordson tractors were often converted into semi-tracked, especially the 'Rotaped', invented in 1941 by O. Singer from London, which was originally built by George Monroe Limited, Waltham Cross, Hertfordshire. The first public demonstration of Rotaped took place in April 1942 near Harlow, Essex. G. Monroe claimed that the traction increased by 100% while decreasing the ground pressure to 0.5 kgf/cm2. But Singer went in 1946 to embark on rubber tracks.
From 1950, Leeford Limited, London, take back the factory and introduced a system of rigid rail to keep fit of the track but they returned to the traditional chain to maintain the whole. Manufacturing continued until 1967.
