John Fowler (11 July 1826 – 4 December 1864) was an English agricultural engineer who was a pioneer in the use of steam engines for ploughing and digging drainage channels. His inventions significantly reduced the cost of ploughing farmland, and also enabled the drainage of previously uncultivated land in many parts of the world.
Fowler was born in Melksham, Wiltshire, the third of five brothers. His father, John Fowler senior was a wealthy Quaker merchant, who had married Rebecca Hull. As well as five sons, they also had three daughters. When he left school Fowler followed his father’s wishes and began working for a local corn merchant, but when he came of age in 1847 he turned his back on the corn business and joined the engineering firm of Gilkes Wilson and Company of Middlesbrough. Amongst other things, the company was involved in building steam locomotives and colliery winding engines. The company built a number of locomotives for the .
Fowler might have remained with the Middlesbrough firm and made his reputation there, had it not been for a chance visit to Ireland in 1849, probably on business. This was at the time of the Irish potato famine, and Irish agriculture depended on the potato crop whilst much of the land was uncultivated due to poor drainage. This affected Fowler and he was convinced that there must be a way of bringing more land into production. The normal way to drain agricultural land was to use a mole plough to dig a subterranean drainage channel. The mole plough has a vertical blade with a cylindrical “mole” attached to the bottom. The mole is pointed at the front end, and as it moves through the soil, it leaves a horizontal channel into which porous drainage pipes can be laid. However this required considerable tractive power, so that the size of the plough was limited by the strength of the teams of horses that pulled it. Fowler returned to England and developed a horse-powered ploughing engine that would dig drainage channels.
Fowler's ploughing engine dragged itself across the field on rollers, pulling the mole plough as it went. The engine was driven by a team of horses that walked round a capstan, winding in a rope which was passed through a pulley securely anchored at the far end of the field. The mole would have a string of drainage pipes attached at the rear end and these would be dragged through the channel created by the mole. On completing each length of drains, the engine would be turned, the rope would be let out and the pulley repositioned ready for the next length. Fowler had trouble with the capstan gears and with the rope slipping on the capstan, but was able to demonstrate his engine at a meeting of the Royal Agricultural Society of England at Exeter in 1850. He was able to lay a drain at a depth of 2 ft 6 in (0.76 m) in heavy clay. His invention was awarded a silver medal and was reported as "altogether the most important feature of the exhibition."
