According to different classification criteria, lawn mowers can have the following divisions:

1, according to the travel points: intelligent semi-automatic tow type, rear push type, mount type, tractor hanging type.

2, according to the power points: human and animal power drive, engine drive, electric drive, solar drive.

3. According to the method: hob type, rotary knife type, side hanging type, sickle type.

4, according to requirements: flat, half-waist, truncated.

The hand-held rotary mower is generally equipped with a knife-free cutting disc. The high-strength nylon rope is used as a forage cutting part. The flexible structure is not afraid of hitting a rigid obstacle. It is safe to use and easy to replace.

The mower works in a reciprocating and rotating manner. Its high mowing efficiency saves time and achieves the functions of green environmental protection and beautifying the environment. It is easy to operate, convenient and efficient, so it is widely used. The machine is small and suitable for small and medium sized lawns. Use the lawn mower to determine the height of the stubble after cutting the grass according to the requirements, which is very convenient to use.

When cutting grass, it can only be trimmed horizontally along the slope, but not along the slope. Modern lawn mowers are more conducive to operation.

Hanging mower

The sample of the hanging lawn mower is formally a type of hanging lawn mower that is side-hanging on the body and one is on the back. In comparison, the side-mounted type is lighter and more durable and more efficient.

Side-mounted mower

Reasons for durability:

(1) In theory, using the same engine to achieve the same function, the more the structure

 Complex, the more factors that fail, the more complex the piggyback structure is, so it is prone to problems. The actual use is also the case, the piggyback is prone to problems.

(2) From the actual situation, the domestic brush cutter market is basically a professional market, which is a machine that is durable. Therefore, the domestic market basically does not use piggyback, almost all of them are side-mounted.

Hanging mower

The structure is simple, light and flexible. There are three types of front suspension, side suspension and rear suspension. Later mounted lawn mowers are the most widely used. The reciprocating mower consists of main components such as cutters, cutter drives, cutter lifts, safety devices and grass blocking devices. The cutter works and is constructed in much the same way as a cutter for a grain harvesting machine.

The blade used has both a light edge and a toothed edge. Light blade blades are generally used. The cutter drive is also similar to the grain harvester, with an offset crank mechanism and a pendulum ring mechanism. Due to the high density of forage growth and high water content, the average speed of moving knives is higher than that of grain harvesters, generally 1.6 to 2.0 m/s. The cutter lifting device is generally operated by a hydraulic system, which is quick and convenient to lift, and can ensure the adaptability of the cutter to the complex ground.

Reciprocating

The reciprocating lawn mower cuts the grass by virtue of the relative shearing motion of the cutter and the fixed knife on the cutter. The characteristics are that the cutting is neat and the power required for the unit cutting is small; but the adaptability to the different growth states of the pasture is poor and easy to block. Suitable for flat natural pastures and artificial grasslands of general production. Since the cutter vibrates during operation, the work speed is limited. The cutting speed of the moving knife is generally less than 3 m / s, and the forward speed of the work is generally 6 to 8 km / h.

Rotary mower, the cutting speed of the blade on the high-speed rotating cutter head impact cutting cutting grass (circumferential speed of the blade root) is as high as 60-90 m / s. The work is stable and the work speed can reach more than 15 km/h. The choice of the blade of the mower is very important, it means the quality of this weeder. Weeding with a lawn mower is better when the grass grows to 10-13 cm (cm). If the grass grows too high, it should be done in two steps. Cut the part first, then cut the part. When using the lawn mower, use both hands to maintain the handle and keep a certain inclination to the side of the fruit tree so that the cut weeds fall as far as possible to the fruit trees. Open the medium speed throttle and advance at a constant speed to save fuel consumption. When the resistance is too large or the obstacle is encountered, the blade will immediately swing back to avoid damage. The blade can be used while changing the edge of the blade. Replacing the blade is also easier than a reciprocating mower. On the rotary mower, in addition to the safety device similar to the reciprocating mower, a protective cover is added above the cutter to ensure personal safety.

Note: When the rotary mower cuts grass, it relies on the high-speed rotation of the blade to cut the grass. If the line speed of the blade is not enough, the grass cutting effect is not good. Therefore, when cutting grass, use a large throttle high speed. In addition, the mower's carburetor and automatic speed control device make it consume less fuel when the throttle is large. Only when it has a load, its speed will reach 2800r.p.m from the no-load 3400r.p.m. Therefore, it is not necessary to use a small throttle because it is necessary to save fuel, and the grass cutting effect is not good.

It is characterized by strong adaptability to pasture and is suitable for high-yield grassland, but the cutting is not neatly tidy, the heavy cutting is more, and the power required for unit cutting is larger. There are two types of drum type and rotary type:

Roller mower

The drive of the drum mower is located above the cutter, which is also known as the upper drive rotary cutter.

Drum mower schematic

 Grass machine. A drum mower is typically equipped with 1 to 4 vertical cylindrical or conical drums juxtaposed. A cutter head for articulating 2 to 6 blades is arranged under each drum, and the rotation trajectory of the blades on the adjacent cutter heads has a certain amount of overlap to avoid missing cuts. The drum is driven by a belt or a bevel gear, and the adjacent two drums are relatively rotated, and the cut grass is placed under the pair of rollers, and the grass is laid back into a neat grass strip. Can meet low cutting requirements, but the structure is not compact enough.

Rotary mower

The Rotarymower's transmission is located below the cutterhead, but the cutterhead has a higher position due to the transmission below. To ensure low cut and reduce heavy cut, the cutter head is usually tilted forward by a certain angle. When the resistance is too large or the obstacle is encountered, the blade will swing back to ensure personal safety. There is also a cutterhead hinged special nylon rope that is cut by centrifugal force. The configurations of the blades on adjacent cutters are interlaced, and the trajectory of the blades has a certain amount of overlap. The cutter head is generally driven by a gear, and the steering of the adjacent cutterhead is reversed. Compact structure, smooth and reliable transmission.

Lawn weeder

Lawn weeders are also known as lawn mowers. According to the requirements of the lawn, the height of the stubble after the mowing is determined. The height of the grass is cut by one-third of the original height of the grass. Due to the special structure of the weeder, the grass can only be trimmed horizontally along the slope. It can't be trimmed down the slope. Be especially careful in special places, such as turning on slopes, beware of caves, trenches, mounds, and other obstacles in the grass.

The new stroller mower, no longer has a lawn mower, a backpack/side-mounted mower, you have to carry it on your lawn mower, it will be very tired in a few minutes. The lawn mower is convenient, light and flexible. It can be used to harvest large wheat, rice, beans, shrubs, reeds, barley, alfalfa and fish grass regardless of the plains, hills, terraces, triangles and other large and small fields. And other crops. The operation is simple, the work efficiency is high, and an acre can be cut per hour, and it can also be carried by one person.

Advantages: 1. Mowing the grass cleanly, trimming neatly, adjusting the height, left and right, no need to spend effort before and after. 2, can be trimmed (weeding) in lawns, orchards, manors, gardens, and mountains. 3. Don't bend over when you work, you can use it for both men and women. Replace the corresponding knives, attach the upper and lower pallets and a safety shield, and harvest shrubs, pastures, reeds and tea garden branches and trims.

Other kinds

A Swiss company called Husqvarna designed a solar hybrid automatic lawn mower, the solar lawn mower "Walley", which is the world's first automated lawn mower. It can be powered by battery or powered by solar energy.

Watt is a lawn mower that can handle 22,500 square feet of grass and can even handle grass with a certain slope. When solar energy is not available, the mower can be powered by a battery and can last for an hour. It takes 45 minutes to fully charge the battery. Therefore, this is a new type of lawn mower that conforms to the 21st century environmental protection theme. In response to the needs of the environment, the power will be very popular and will be gradually promoted in the market.
