History of agriculture the New Leicester sheep. Machines were invented to improve the efficiency of various agricultural operation, such as Jethro Tull's seed drill of 1701 that mechanised seeding at the correct depth and spacing and Andrew Meikle's threshing machine of 1784. Ploughs were steadily improved, from Joseph Foljambe's Rotherham iron plough in 1730 to James Small's improved "Scots Plough" metal in 1763. In 1789 Ransomes, Sims & Jefferies was producing 86 plough models for different soils. Powered farm machinery began with Richard Trevithick's stationary steam engine, used to drive a threshing machine, in 1812. Mechanisation spread to other farm uses through the
Seed bead concentric layers of color or stripes of color can be used to make patterns of color in seed beads. Seed bead machinery uses glass rods softened to a red heat, fed into a steel die stamp that forms the shape of the bead with a reciprocating needle that forms the hole. Manual and automatic machinery is in use in the Czech Republic. As the steel dies wear eventually, they are replaced. During the last decade, a new shape of Japanese seed bead, the cylinder bead, has become increasingly popular. They were invented by Masayoshi Katsuoka of the Miyuki Shoji Company
