grain and could cut weeds。 People pushed the machine and driven a
rotary knife to cut grass through a gear drive。 This was the prototype
of the mower。
In 1830, British textile engineer Bill Pudding obtained a patent for a roller mower and received praise.
In 1832, Lansmus Agricultural Machinery began mass production of roller mowers.
In 1831, British textile master Kabila obtained the exclusive patent for the world of lawn mowers.
In 1833, Lansmus Agricultural Machinery began mass production of roller-type mowers. In the 19th century, this lightweight and well-controlled roller mower was widely used in green belts near traffic roads.

by an internal combustion engine. Its principle has been extended to
What we usually see in rural TVs in the United States is this weeder, which makes it very easy to trim the lawn.
With the rapid rise of the turf industry, China began to use the reciprocating mower in the 21st century. At the end of the 19th century, it was extremely laborious to protect a lawn. For

the work is done, the lawn is full of sawed blades of grass, and then
the blades of grass on the ground are picked up to feed the cattle and
sheep on the farm. This saves time and reduces damage to the grassland. It
consists of a parallel four-bar lifting device, a frame, a single-wing
