Rotary hinged mower - characteristics and operation principle

Each farmer has on his farm at least one rotary mower. Without it, it is almost impossible to quickly prepare food. The application of this tool in the agricultural sector greatly accelerates the productivity of harvesting and the speed of fodder harvesting. In addition, the work of this tool almost does not require the expenditure of a person's physical strength. What is good is a rotary hinged mower , how does it work and how much does it cost? You will know the answers to these questions right now.

What is it?

Rotary hinged mower is the most common type of forage hinged tools that are used not only far abroad, but also in many CIS countries. Such great popularity is explained by the fact that this mechanism has a lot of advantages that allow it to keep the leading positions in the rating of agricultural equipment.

Benefits

Such a tool as a rotary hinged mower works at increased translational speeds, so that it quickly and qualitatively provides skew and collection of grass. On the field, such a tool carefully places the mowing in a row, which is very convenient for loading and transporting hay. It should be noted that the rotary hinged mower (КРН-21 including) can effectively produce the bevel not only of high-yielding plants, but also of dead grasses.

Principle of operation

Each rotor-type tool at the bevel of grasses performs rotational movements of the tool, which are provided by the shafts of the running motoblock or tractor. Thus, these devices use the power of the tractor's drive to further drive their own mecha- nisms.

Several types of power transmission may also be involved in the collection of grass:

• Klinomernaya.
• Conical.
• Cardan.
• Toothed spur gear.

The very same rotary hinged mower ("Dawn" is one of the best in this segment) is a kind of bar, to the top of which are fixed special rotors (hence the name "rotary"). Each mechanism, fixed on top of the "beam", is equipped with moving knives, which carry a fast bevel of plants.

The use of the rotary type of mowing makes such tools the most effective among all its other competitors. So, for example, if ordinary grass mowers use only 30-35 percent of the tractor's energy, then rotary mowers use about 60-65.

Cost

At the moment the price of a rotary mower can be from 5-10 to 130 and more than thousand rubles. Why such a wide range of prices? The fact is that the rotary hinged mower can be used not only on tractors, but also on motoblocks. Attachments for the latter are always several dozen times cheaper than those for tractors. Hence, there is such a solid runaway between the cost of a professional and unprofessional mower to mow down agricultural land.
