Which of the chosen plow is the correct

People have been using the plow since the beginning of farming, and even then they knew that with this tool they could change the ability of the soil to produce more crops. The main thing is to figure out which of the selected plows is correct, that is, the best one for a particular field. Although everyone plows the land, they do it: - to loosen the soil (on clay soils this procedure allows the soil to warm up faster), - to saturate it with oxygen, - to mix its components: salts (there are more of them in the soil in humid climates), moisture (also in humid regions where moisture and salts accumulate in the bottom layer of the soil surface), crop residues (they are on all fields, regardless of climate). Plowing also reduces erosion processes in the soil. And autumn plowing, in addition to destroying the roots and seeds of weeds, also contributes to more efficient freezing of the soil in order to destroy pest larvae and the dwellings of underground rodents.

Although recently resource-saving technologies in soil cultivation ( mini - till and no - till ). but even there, albeit less often (not every season), plows are used. You can't do without a plow when developing new fallow lands, and the technology of growing rowed crops and vegetables provides for the use of a plow (plowing) without fail.

Several criteria for choosing the right plow

In general, there are only a few determining factors or characteristics on which plow selection is made.

First of all, it is a dependency on the tractor-tractor. A tractor that is too powerful will very easily “carry” a 3-furrow plow across the field and hardly “feel” it. And the plow frame, on the contrary, will be subjected to excessive loads. Which will lead to an imperceptible result in the form of a low yield. To control this, it is necessary that the maximum power for the plow corresponds to the rated power of the tractor. But on the other hand, tractor power should be enough for the tractor to work without wear, with unsatisfactory plowing quality and with low productivity. Usually, the ratio of tractor power to plow width is calculated based on a norm of 40 hp . per 1 plow body. Then, for example, for an eight-furrow plow, you will need a tractor with a power of 320 hp , with a deviation of plus / minus 20 hp .

Another initial factor will help you make a decision - this is the size of the field or the total size of the fields of the farm - if we are talking only about hundreds or other hectares, then a wide-cut plow, for example, 12 meters, will also be overkill. As a compromise solution, the choice of a plow with removable one or two bodies can become.

In the case when the agricultural company already has a powerful tractor. and the field sizes are not large enough, it is still more economically productive to use the maximum load on the tractor with trailed or semi-mounted plowswith a wide grip and consisting from 10-13 buildings. Don't forget that your tractor has the appropriate three-point hitch. If it is not available, you must either order one or purchase a special adapter trolley from the supplier of these tractors.

Disadvantages of wide-cut plows

The main disadvantage of wide-cut plows is their "sluggishness". This means that a wider plow will spend noticeably more time on each turn at the edge of the field, and then you will still need to additionally pass a mounted plow over those turns.

And here the loss is multiple: the main plow passes through the field more slowly, additional plowing with another plow - and this is still a waste of time, the need to have an additional plow - and this is already a financial loss.

According to experts, for agricultural firms with medium-sized fields, six-eight-furrow plows will be optimal, for farms with small and/or complex geometry fields, small three-four-furrow plows . And only for large fields wide-cut plows are effective, and their use is justified.

In general, width is so important, not only as a constant value. There are plows on the market in which it is fixed, there are also those with variable width - the change is possible step by step (step - 5 cm) and with smooth adjustment using the hydraulic system (adjustment is carried out from the tractor cab). Of course, “you have to pay for convenience”, so the smoothness of the adjustment should be justified: for example, the presence of different types of soil on the farm, or if necessary, plowing on a hilly field, or when working in different seasons of the year.

Specifically, such regulation can occur as follows: in the period of early spring. in case of high soil moisture and the need to plow on a hill, climbing to its top, in order for the tractor to cope with the task, you should slightly narrow plow grip, and when descending, on the contrary, increase it. Smoothness and control from the cab in this case are needed, since the angle of ascent, as well as the angle of descent, can change, and you have to reset the width at least twice on each circle.

About work on the earth on system “on-land”

Modern models often use 710mm wide or larger tires and track trucks in the chassis . or twin wheels. However, to extend the life of the tractor (first of all, its engine and transmission), it is not the types of chassis that are more important here, but the use of the “ on-land ” system - the movement of the tractor outside the furrow. Otherwise, changing tires after plowing in autumn with dry weather can become an annual procedure.

Measures to protect the plow from the negative effects of the earth

In order to protect the plow body from the effects of adverse soil conditions (for example, stony or excessively compacted soils), a plow with protection based on spring springs or hydraulics is best. In addition, for particularly difficult soils, a plow model with reinforced tines and body, as well as the chassis with special wear-resistant rubber. When working on sticky. In heavy soils, non-standard feather (strip) dumps will become effective. The earth sticks to them less, which makes them also suitable for plowing, regardless of the time of year.

For sunflower or corn fields during autumn plowing, plows with an increased mouldboard and possibly with skimmers are required.

Another feature and trend in the development of modern production of plow equipment is an increase in the automation of plowing processes. On the market there are plow models with ISOBUS systems - with the ability to manage the plow settings process, without leaving the cabin. As well as models with installed navigation equipment.

And finally. The last piece of advice for choosing the right plow is to have it maintenance with the help of a trusted company with long practical experience and direct contractual supply of original spare parts from equipment manufacturers. One of these is the Grozber Ukraine company
