The name given to long series of Qualcast roller mowers commencing with the initial model in 1932 and continuing into the 1970s. The majority of these machines were conventional twin-handled manual chain driven mowers until the introduction of the "Powered Panther" in the 1950s with its tiny J.A.P. engine, although it was possible in the 1930s to obtain bolt-on power units of various sorts. The "Panther" continued to be made under the Suffolk name into the 1990s. The "Superlite Panther" was a lightweight post-World War 2 machine with diecast aluminium side plates, whilst the "Super Panther Electric", introduced in 1962, was a mains electric machine. Battery powered versions were also available.
