The history of lawn mowers

It has been around since 1805, when lawn mowers were human and had no power to support them.
In 1805, the Englishman Pracknet invented the first machine that harvested grain and could cut weeds.
In 1830, British textile engineer Bill Pudding patented a drum mower to great acclaim.
In 1832, the Lancems Agricultural Machinery Company began mass production of drum mowers.
In 1831, the British master weaver Kabilia obtained the world's exclusive patent for a lawn rolling machine.
In 1833, the Lancems Agricultural Machinery Company began mass production of drum mowers. In the 19th century, this lightweight, easy-to-handle drum mower was widely used in traffic roadside green belts.
In 1902, the Englishman London Enns built a drum lawn mower powered by an internal combustion engine, and its principle is still used today.

This is the kind of weeding machine that we usually see on American country TV, and it can be used to mow the lawn very easily
With the rapid rise of the lawn industry, China began to use accumulating reciprocating lawn mowers in the 21st century. At the end of the 19th century, protecting a lawn was physically demanding. For example, in a large estate in Blenheim, if you employ 200 workers, 50 of them are lawns. During the season when the grass grows wildly, the grass needs to be cut about every ten days. The mowers mow in rows with very long tools (sickles: the blades are jagged and need to be sharpened often with a whetstone to keep them sharp) (in fact, they work more like sawing grass with a saw). After the work is completed, the lawn is full of sawn blades of grass, and then the blades of grass on the ground are picked up and used 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-rod lifting device, a frame, a left and right single-wing hoeing device, and a deviation adjustment device for the whole machine.
