Lawn Mower Development History

It has been around since 1805, when lawn mowers were powered by humans and had no power support.
In 1805, the British Praknet invented the first machine that harvested grains and cut weeds. The machine was driven by people, and the rotary knife was driven by gear transmission to cut grass. This was the prototype of the lawn mower.
In 1830, Bill Pudding, a British textile engineer, patented the roller lawn mower and won praise.
In 1832, the Ransoms Agricultural Machinery Company began mass production of drum mowers.
In 1831, the British textile master Cabiria obtained the world's exclusive patent for tumblers.
In 1833, the Ransoms Agricultural Machinery Company began mass production of drum-type lawn mowers. In the 19th century, this light and easy-to-handle drum mower was widely used in green belts beside traffic roads.
In 1902, the Englishman London Ernes made a drum mower powered by an internal combustion engine, and its principle is still in use today.
We generally see this kind of weeder on American country TV, and it can easily mow the lawn with it.
With the rapid rise of the lawn industry, China began to use power-storage reciprocating lawn mowers in the 21st century. At the end of the 19th century, maintaining a lawn was a physically demanding task. For example, in a large estate in Blenheim (a village in western Bavaria, Germany), if 200 workers are employed, 50 of them are lawn maintenance. During the overgrown season, the grass needs to be mowed about every ten days. Lawnmowers hold very long implements (sickles: the blades are serrated and need to be sharpened frequently with a whetstone to keep them sharp) in a row to mow the grass (actually work more like sawing the grass ). After the work is done, the lawn is full of sawed grass blades, and then the grass blades on the ground are picked up and used to feed the cattle and sheep on the farm, which saves time and reduces damage to the pasture. It consists of a parallel four-bar lifting device, a frame, a left and right single-wing weeding device, and a deviation adjustment device for the whole machine.
