This name mainly refers to a range of American sidewheel mowers with intermediate gear drive which was to be imported into the UK in vast numbers from the late 1870s to the 1950s making it the mower with the longest recorded production run. The original manufacturers were the Supplee Hardware Co. of Philadelphia, and the British agents from 1878 were Lloyd Lawrence & Co. which later became Lloyds of Letchworth. In 1924 these agents started manufacturing "Pennsylvania" mowers in this country. These mowers can be identified by the letters "PQ" (Pennysylvania Quality) cast into the frames. Roller mowers and pony mowers were also made under the "Pennsylvania" name, as was a 1949 bank trimmer, an 8 inch machine with a front roller, driven by a mains electric motor. The Pennsylvania "Trio" was a triple pony drawn gang mower offered by Lloyds in 1923.
