Brief introduction of lawn mower

Since 1805. At that time, the lawn mower was human and had no power support. 1805, British Plucknett invented the first machine that can harvest grain and mow grass. The machine is driven by people, and the rotary knife is driven to cut grass through gear transmission. This is the prototype of the lawn mower. 1830, British textile engineer Bill Pudding obtained a patent for the drum mower. 1830, British textile engineer Bill Pudding obtained the patent of drum mower and won favorable comments.

1832, Langsam Sisi Agricultural Machinery Company started mass production of drum mowers.

183 1 year, the British textile master kabylie obtained the exclusive patent of lawn mower in the world.

1833, Langsam Sisi Agricultural Machinery Company started mass production of drum mowers. /kloc-in the 0/9th century, this kind of portable and easy-to-control drum mower was widely used in the green belt beside the traffic road. 1902, Londoners in England made a drum mower powered by internal combustion engine, and its principle has continued to this day.

1902, an Englishman, Gaines, made a drum mower powered by an internal combustion engine, and its principle has continued to this day. What we usually see on American country TV is this kind of lawn mower, which can be easily used to mow grass.

With the rapid rise of lawn industry, China began to use energy-saving reciprocating lawn mower in the 20th century. At the end of 19, protecting a lawn was extremely exhausting. For example, in Brenheim, a village in western Bavaria, if 200 workers are employed, 50 of them will maintain the lawn. In the season of grassland overgrowth, the grass is mowed every ten days. The lawn mower holds a very long tool (sickle: the blade is serrated, so it needs to be polished with a grindstone frequently to keep sharp) and cuts grass continuously (in fact, it works more like sawing grass with a saw). After the work is finished, cover the lawn with sawn grass leaves, and then pick up the grass leaves on the ground to feed the cattle and sheep on the farm, which not only saves time, but also reduces the damage to the grassland. It consists of a parallel four-bar lifting device, a frame, a left-right single-wing weeding device and a whole machine deviation rectifying device.
