Rotary plow: characteristics and description

Today in agriculture only three main types of plows are used - reversible, disc and rotary. The latest variety of attachments is primarily used for deep tillage without turning the formation. The main working tool of the rotary plow is the plowshares mounted on the cast coulter. This type of equipment can be used on any type of soil, including heavy and over-dried ones.

general description

Compared to a revolving or disk, a rotary plow has a slightly more complex design. Movable shares on the axis in such equipment are fixed by means of shafts . By the principle of operation, rotary plows can be compared with conventional cultivators. Plowing the land when using them is done by turning the axis. In this case, two shares are usually responsible for the actual cultivation of the soil, and two more for loosening it. When turning, the blades change places. After applying the rotary plow, there is no need to use a loosening mill.

Such equipment operates faster than revolving. As a result, when using it, agricultural machinery (even on difficult soils) moves more quickly, which saves time for plowing.

Features of work

When using a rotary plow, active plowshares cast the earth only in one direction. At the same time, the passive ones compare the ridges, raising them. When turning the tractor loop at the end of the row such a plow does not. This becomes possible due to the mobility of its axis. With the reverse movement, the plow simply rotates on its own.

Main advantages

The rotary plow is, in fact, the most modern type of attachment designed for tillage. Its use gives farmers the following benefits:

• on the field after cultivation there are no large clods of earth;

• the soil is saturated with oxygen as much as possible;

• the number of working passes is reduced;

• tractor fuel consumption is reduced and tire wear is reduced.

Also, the use of a rotary plow reduces the cost of weed control and provides the most uniform mixing of organic substances contained in the soil. This modern equipment does not leave on the field and furrows. This, in turn, significantly improves the moisture and air exchange of the earth. When using a rotary plow, the farmer gets the opportunity to produce a series of successive cultivations.

Scope of use

Today rotary plows are not only the most modern, but also the most common type of attachment. They are used for tillage everywhere. Such plows are used for plowing as large agricultural enterprises, as well as farmers and even ordinary owners of household plots.

Equipment of this type can be used for tillage for almost any kind of crop. Since the rotary plow is loosening the earth much better than other types of attachments, it is often used even for plowing rice fields. This convenient tool is also used for cultivating virgin lands . In this case, the rotary model is usually used in conjunction with drives oh . In household plots and on farm fields, such equipment can also be used as a potato digger.

Where to buy a model for a mini-tractor?

Thus, rotary plows are used by homeowners as well as small and medium-sized farmers quite often. Such equipment in small farms is usually mounted on a mini-tractor. For each model of such equipment, in most cases , only a rotary plow designed specifically for it is suitable . MTZ, for example, is a brand of mini-tractors used by farmers most often. It is believed that for such models it is best to use attachments sold by the companies Belarus and Dofgan. But, of course, there are universal rotary plows on the market, which can be used with almost any tractor.

Many farmers are interested, of course, and in where it is actually possible to purchase such attachments. It is easiest to buy the most suitable rotary plow for a minitractor in one case or another , of course, in a company specializing in the sale of agricultural assistants. Also, in order to save money, many farmers also purchase used equipment of this type. You can buy a used rotary cultivator , for example, via the Internet, by announcement.

Imported or domestic?

In addition to “Belarus” and “Dofgan”, on the market today, of course, there are many other models of rotary plows. If desired, the farmer can purchase both imported and domestic equipment of this type. The main advantage of the models produced by Russian companies is their maximum adaptability to the climatic conditions of our country. Such plows, unlike imported ones, can be used on clay clay soils. It is also allowed to apply them on lands containing small stones.

Of the imported equipment in the domestic market, Chinese models are most often sold. They cost about the same as domestic ones. Plowing the land with their use is quite convenient. Regarding the reliability of such equipment, domestic farmers also have no special complaints . However, imported plows have one rather significant drawback. It is quite difficult for them to find spare parts. In addition, the market today, unfortunately, is selling a lot of old imported rotary plows, repainted for new ones. Some disadvantage of such models is also considered that the instructions for their use are usually written in Chinese.

The best models and their characteristics

Of the domestic plows among small and medium-sized farmers, as well as among the owners of household plots, the PM-20 and 25 models are especially popular today . They are designed specifically for aggregation with mini-tractors. These two-point rotary plows with three-point connection have the following technical characteristics.

There are new PM-20 and 25 plows about 70 thousand rubles. The companies implementing them usually offer, including their delivery to any regions of Russia. The manufacturer also gives a guarantee for them for one year.

Of the imported models of rotary plows, farmers most often purchase RT-120 and 125. The technical characteristics of these two-frame plow models are presented in the table below.

RT-120 and 125 plows are made in China. You can use them with any mini-tractors with a capacity of 18 liters or more. from. Their aggregation is carried out at three points. RT-120 and 125 rotary plows can be purchased in Russia from dealers or online. The price of new models starts at 70 thousand rubles. Second-hand equipment of this brand can be bought for 30 thousand rubles.

How to choose a rotary plow for walk-behind tractor?

Mini-tractors are usually used for plowing land only in large farms. Summer residents and owners of small household plots in the village are more likely to use motor blocks for this purpose. Of course, the rotary plow can also be aggregated with such low-power equipment. K ultivators of this type most often initially come complete with a walk-behind tractor. But, of course, you can purchase rotary equipment separately.

The power of motoblocks ranges from 3.5 to 10 liters. from. Based on this indicator, it is worth choosing a rotary cultivator. Unfortunately, versatile plows of this type, designed for all walk-behind tractor models, practically do not exist on the market. Therefore, most likely, it will be necessary to acquire a used model from a set of a motor block of the same brand.

DIY plow

There is equipment of this variety, even used, intended for a mini-tractor, as you might have noticed, is quite expensive. For a walk-behind tractor, it’s quite difficult to find such a cultivator. Therefore, many owners of farms and household plots would probably like to know how to make a rotary plow with their own hands.

Making such equipment yourself is actually not particularly difficult. The steps for assembling a rotary plow look like this:

• a cylindrical blade is made;

• a ploughshare is installed in a metal sheet at an angle of 45 degrees;

• the share is docked with the side shield;

• the blade joins the ploughshare;

• the resulting working part is welded to the base of the plow from a metal pipe;

• on the other side, a mount for a walk-behind tractor is welded to the pipe.

Of course, a homemade rotary plow will need to be supplemented with an axle with wheels. This element is welded from the bottom at the final stage.
