The development history of lawn mower
In 1805, the Englishman Praknett invented the first machine that harvested grain and could cut weeds. The machine was driven by a man and the rotary knife was driven by a gear drive to mow the grass. This is the prototype of a lawn mower.
In 1830, the British textile engineer Bill Pudding patented a roller lawn mower and won praise.
In 1832, Lansems Agricultural Machinery Company began mass production of drum lawn mowers.
In 1831, the British textile master Kabila obtained the world's exclusive patent for a tumbleweed machine.
In 1833, Lansems Agricultural Machinery Company began mass production of drum-type lawn mowers.In the 19th century, this lightweight and easy-to-control roller lawn mower was widely used in green belts next to traffic roads.
In 1902, the British London Enns manufactured a drum-type lawn mower powered by an internal combustion engine, and its principle has been used to this day.
What we usually see on American country TV is this kind of weeding machine, which can be used to mow the lawn easily.
With the rapid rise of the lawn mower industry, China began to use accumulative reciprocating lawn mowers in the 21st century.At the end of the 19th century, it was extremely labor-intensive to protect a lawn.For example, in a large manor in Blenheim (a village in western Bavaria, Germany), if 200 workers are hired, then 50 of them maintain the lawn.In the season when the pasture is growing wildly, the grass needs to be cut about every ten days.The lawn mowers are armed with very long tools (sickle: the blade is serrated, and you need to use a whetstone often to polish it to keep it sharp) to mow the grass in a row (in fact, it works more like sawing grass with a saw).After the work is completed, the lawn is full of sawn grass leaves, and then the grass leaves on the ground are picked up to feed the cattle and sheep on the farm, which saves time and reduces the damage to the pasture.It consists of a parallel four-pole lifting device, a frame, a left and right monoplane weeding device, and a bias adjustment device for the whole machine.
