The lawn mower is composed of a cutter head, an engine, a traveling wheel, a traveling mechanism, a blade, a handrail and a control part. It consists of a parallel four-bar lifting device, a frame, a left and right wing weeding device, a complete machine deviation adjustment device, a comb tooth rotating bevel gear speed-increasing transmission mechanism and a comb tooth profiling depth adjustment device. Compared with manual weeding, the efficiency is increased by 8-10 times, the rate of damage to seedlings is low, and the rate of seedling removal is high.

According to different classification standards, lawn mowers can be divided into the following types:

1. According to travel: intelligent semi-automatic trailer type, push-back type, installation type, tractor-mounted type.

2. According to power: human and animal power drive, engine drive, electric drive and solar drive.

3. Divided into hob type, rotary cutter type, side hanging type and flying knife type.

4. According to requirements, it can be divided into flat type, half waist type and truncated top type.

Hand-held rotary lawn mowers are generally equipped with bladeless cutting discs and use high-strength nylon rope as the forage cutting part. It has a flexible structure and is not afraid of encountering rigid obstacles. It is safe to use and easy to replace. The working methods of lawn mowers are reciprocating and rotating. The mowing efficiency is high, it saves time greatly, realizes the functions of environmental protection and beautification, and the operation is simple, convenient, high-efficiency, and widely used. The machine is small in size, suitable for small and medium sized lawns. When using a lawn mower, the stubble height should be determined according to the requirements, which is very convenient to use. When mowing the grass, you can only cut horizontally along the slope, not downhill. Modern lawn mowers are more convenient to operate.

Rotary lawn mowers rely on the high-speed rotation of the blades to cut grass. If the linear speed of the blade is not enough, the effect of mowing is not good. So when mowing the grass, use a high throttle and high speed. In addition, the carburetor and automatic speed regulator of the lawn mower make the lawn mower under the condition of high throttle, if there is no load, the fuel consumption will be very low. Only when it is fully loaded, its speed will reach 2800r.p.m from 3400r.p.m. at no load, so there is no need to use a small throttle to save fuel, and the mowing effect is not good.

According to the requirements of the lawn, the stubble height after mowing should be determined, and the mowing height should be one-third of the original grass height. Due to the special structure of the lawn mower, mowing can only be done horizontally along the slope, not up and down along the slope. Be especially careful when turning in special places such as slopes, and beware of obstacles in the grass, such as caves, trenches, and mounds. The newly launched cart-type lawn mower is no longer a back-type lawn mower. The backpack/side-mounted lawn mower that you carry on your back when you mow the lawn will be very tiring for a few minutes. The hand-changing self-propelled lawn mower is convenient, light and flexible, and is used for harvesting crops such as wheat, rice, beans, shrubs, reeds, barley, alfalfa, fish grass and so on. , Regardless of the size of the fields such as plains, hills, terraces, triangles and muddy land. The operation is simple and the work efficiency is high. It can cut one mu of land per hour and can be carried by one person.
