Joseph Foljambe in Rotherham, England, in 1730, used new shapes based on the Rotherham plough, which covered the mould board with iron.


It may have been the first plough widely built in factories and commercially successful there. In 1789 Robert Ransome, an iron founder in Ipswich, started casting ploughshares in a disused malting at St Margaret's Ditches.


Looking for a polished, slicker surface for a plough, he experimented with portions of saw blades, and by 1837 was making polished, cast steel ploughs.


The energy required was lessened, which enabled the use of larger ploughs and more effective use of horse power. ===Balance plough=== The advent of the mobile steam engine allowed steam power to be applied to ploughing from about 1850.


Only by reducing the number of shares could the work be completed. ===Stump-jump plough=== The stump-jump plough, an Australian invention of the 1870s, is designed to break up new farming land that contains tree stumps and rocks expensive to remove.


It was used up until the 1960s in poorer land.
