Mowers are on the list of attachments for modern farming machinery. They are used by both farm enterprises and private land owners. A variety of designs, ways of fastening to tractors and motor blocks, a wide range of capacities and dimensions make it possible to purchase mowers specially for specific needs. In general, the parameters and functionalities that the rotor mower has in modern modifications do not present any problems in the choice, but for a more complete presentation it is worthwhile to consider the technical features and capabilities of this equipment deeper.
Design and operating principle of the
Mowers, as the name implies, provides the process of mowing unwanted or agricultural vegetation in the area. Some models also have auxiliary functions - for example, grass harvesting and weed processing. By design, the rotary mower is a frame on which the working elements are fixed. On the rotors themselves, knives are fixed on the hinge system. The cutting organs are actuated by means
One of the most functional models is a mower-shredder, which, in addition to the rotor and main plank, has a pipeline and engine. During operation, the rotary mower, by means of a special shield, tilts the grass down, and then cuts it. Further, the sloping vegetation is lifted and grinding begins with immersion in a special container.
Important characteristics of
The first criterion in choosing a mower is the cut height. This parameter is not critical in terms of the quality of the mowing process and the productivity of the machine, but it affects the safety when operating the equipment. When working on different terrains, the corresponding cutting height is required - usually 4-7 cm.
Next, we need to consider the grip characteristics - for example, the rotary 2.1 mower is capable of cutting a strip of width 210 cm. There are other models with a working width up to200 cm. This does not mean that such units are less practical or ineffective. The fact is that in close conditions when processing complex patches of irregular shape, they are the ones that can cope with agricultural harvesting operations.
Speed parameters are important in terms of productivity. Cutting devices that rotate at a speed of 3,500 rpm are capable of processing up to 90 m / s. If you want to mow the vegetation without harming the root system, this frequency will be optimal.
Additional features of
It has already been noted that there are models that work as shredders. At the same time, a modern rotary mower can be equipped with other options. So, if it is required to preserve the integrity of the mowing( in the case of yielding vegetation), then it is worthwhile to focus on models that ensure subsequent laying for manual harvesting. Other modifications lay grass in the form of shafts, which is also required at specialized enterprises. A multifunctional rotary mower for a tractor can combine the capabilities of an assembler, stacker or a grass processing unit. Contrary to popular belief regarding the relatively poor quality of aggregates combining several functions, expensive firm models with equal ease and accuracy provide both mowing and further processing of vegetation.
Classification by attachment type
As rotary mowers are applied to attachments, their operation is only possible in combination with movable equipment. It can be a tractor or a motoblock. The locking mechanism differs in design - a trailing device, semi-mounted or fully mounted.
Trailed models have three working surfaces that cut. Such a rotary mower is fixed by means of a special suspension. Semi-mounted machines require an additional device for lifting and fixing - in this capacity a hydraulic cylinder is used. Completely mounted mowers are most common due to their wide autonomy. They are often supplied with an additional grinding function.
Mounting type of cutting structure
Mowers differ in the way the cutting system is installed, with which the rotary mower is supplied in different configurations. In this regard, it is important to take into account the location of the structure - in the front, rear or side. This is a significant difference, which should be guided not only in terms of ease of mowing, but also take it into account with respect to the goals of mowing. For example, if you plan to work with a crop area, then the rear location of the cutting mechanisms is selected, if you want to weed the weed - the front.
In addition, a rotary mower for a tractor can contain several frames in the structure. Each of them will start work either from the tractor drive unit, or from its wheelbase. In this regard, it is necessary to correlate the power potential of machinery and the requirements of the attached equipment from the outset, and also to evaluate the efficiency of the structural combination of the two units.
Mowers for motor blocks
Such models, of course, lose in power and functionality to units intended for a tractor, but in the processing of small areas their use is justified. Typically, this equipment with a hinged system, which is capable of providing a bevel of dense vegetation, grain varieties and even shrubs. The only thing to calculate is the maximum diameter of the barrel, which can be cut by a rotary mower. To the motor block, the system is attached using a special mechanism, supplemented with a drive belt.
In the domestic market of agricultural machinery are presented and mowers of Russian production, and foreign models - as a rule, Eastern European. Perhaps, the flagship of the line of domestic mowers is to call the series "Dawn".These units have optimal characteristics for working on large areas, providing a good speed. In the list of imported stands a rotary Polish mower from the company "Virax".Representatives of this family are distinguished by the quality of the cut with a width of 135 to 185 cm. Belarusian models are also common. In particular, KRN has a wide functionality and decent performance with a cutting width of up to 216 cm.
. In terms of value, everything is just as diverse. For example, if you need to select a mower with average capabilities for a motor block, then you can meet 10-12 thousand. These are models from Chinese agrotechnical companies, so you should be prepared for a relatively low productivity.
A good choice in the middle segment may be a proposal from the mentioned manufacturer Virax - in particular, a rotary Polish mower with a grip of 185 cm will cost 30-40 thousand. Despite a modest cut, a 25-horsepower motor will ensure a clean laying of the vegetation without interfering with the rootsystem.
Russian and Byelorussian units are worth not less than 50 thousand. These are high-quality rotor models, in which polished gears and steel boxes are provided. Models costing from 100 thousand rubles differ in productivity of 2.85 ha / h and have a capture width of at least 210 cm, so this high payoff justifies itself. Search for analogues of similar mowers in the range of 20-40 thousand, of course, is not necessary.
