How to correctly assemble milling machines on a cultivator

Cutter types for a power tiller

Structurally, a tiller is a set of tillage blades, placed on a rotating axle. Such a module consists of two parts, which are installed on the drive shafts of the wheels on either side of the power unit. Thanks to such location, the single-axle tractor is able to move independently during cultivation.

Also, you can select the type of tillers with attached cutters, rotational motion which gives the PTO shaft. The module is located behind the power unit and does not participate in the implementation of the movement. Power tillers such as MTZ, Neva, Proab, Sich, Agro and manufactured in different versions, with and without PTO.

There are virtually no differences in the construction of both mounted and conventional tillers. But the PTO drive module with a double-sided angled reduction is available as an option for the cutter bar with independent rotation.

Active (sabre-shaped)

These power tillers have four groups of knives set at 90˚ intervals. There can be 2, 3 or more such blocks on one side of the drive. The number and width of blades depends on the weight of the power tiller and its power.

The blades are curved strips of high strength alloy steel. For self-made with heat treatment followed by hardening, spring steel 50ХГФА type is well-proven. Knife bends have alternating directions.

Active shearer design enables the unit to cultivate areas with stones and roots without risk of shear blades breakage. But it is reasonable to use this type of equipment on light cultivated soils.

“Goosefoot blades

Cutting elements of such cutters are made in the form of a triangle from strong steel, located on the end of the stand. This arrangement is the reason for the extravagant name “tiller”.

As with active tillers, the width and number of shears depends on the weight and power of the power tiller. Number of cutting elements arranged around the circumference of the knife block, 4 or more. blades for better tillage but also more power from the power pack.

A rotary mower for your power tiller can be quite handy on a country site.

These machines are designed for heavy soils and fallow land. The presence of branched root systems in the soil leads to frequent clogging of the module.

Both tillage tools have advantages and disadvantages. When choosing a variant for self-made, it is necessary to take into account the structure of soils, the required degree of shredding the soil, the layout and power of the power unit, the complexity and method of manufacturing.

Advantages

Milling is now the most important farming technique.

Deep tillage is carried out in two ways. by ploughing and milling. The first method has been the only one for thousands of years, since milling machines simply did not exist before.

The advantage of milling: a good and complete loosening of the soil, aeration and mixing of layers. The plow simply makes a half or full turn of the layer. Strongly structured soils may not be crumbled and can remain in big clods. This requires additional tillage with harrows, cultivators with discs or small disc coulters, or on small plots with a rake.

Milling Machine Basics: Locating the X, Y, and Z axis

Additional operation greatly increases labor and energy costs, reduces overall productivity. No big clods remain after tillage on most soils, and the soil is immediately ready for sowing.

How to choose a gooseneck tiller?

When choosing this important component of a power tiller, first of all, it is important to pay attention to the size of the “goose feet” for the power tiller. It is more about matching the axle diameter of the tool to the planting shaft of your machine model. They are produced in the size of 30 mm and 25 mm.

over, there are three rows of three knives on cutters with diameter of 25 mm. Such products are suitable for power tillers “Texas”, “Neva”, “Caiman”, “Mole” and others. Goosefoot models with an axle diameter of 30 mm are selected for power tillers of Kaskad, Salyut, Caiman Vario, Master Yard and others. On such product there are not three but four rows of knives. And the width of the processed surface is increased.

Another criterion that is worth paying attention to when selecting goosefoot cutters for power tillers is the outer diameter, which, accordingly, depends on the depth of plowing. The bigger the diameter, the deeper the knives are able to cut into the ground. Meanwhile, the quality of “goose-feet” should be good, otherwise metal breakage is unavoidable.

The standard equipment of any make of power tiller requires the presence of the tillers and other necessary parts. But there are situations when it is necessary to increase the power of the unit independently, in order to cultivate the soil better and deeper. To date, anyone can make cutters for power tillers with their own hands, and to do this you need to follow simple instructions, which we will consider in detail in this article.

In agriculture, power tillers have long occupied a leading position in operation, distinguished by the rapid cultivation of the land and the possibility of automatic harvesting. Each model, regardless of the country of the manufacturer, includes additional power units.

As a rule, they are quite enough for quality work on any sites, and there is almost no need to make milling cutters for a power tiller by yourself. But there are situations when the capabilities of a purchased unit do not meet the Russian realities.

There are two types of power tillers: a soil tiller and a sabre tiller

not all Western manufacturers take into account the depth of soil in other countries, specific crops, weather conditions, and other factors that can complicate the operation and increase the chance of a quick breakdown.

In such cases, you can always buy an additional cutter for your specific area or make it your own hands. It is worth noting that in many cases, homemade parts work much more efficiently than the factory ones! Visually, any cutter looks as follows: two parts of the module with a special set of tillage blades are attached to the wheel base, and then adjusted so that one structure does not interfere with the other.

It is worth noting that there is a second type of attachment, working with the PTO.

Such units are mounted on the back of the main structure, and are often found on such models as MTZ, Proab, Agro and others. Despite the difference in installation, all types of cutters are made according to the same scheme.

Depending on the type of operation, the additional devices may be slightly different from each other. The main purpose of the tillers is to destroy weeds and level the ground surface of the plot, but they can also perform other tasks at the same time.

How to correctly assemble a tiller on a power tiller

A single-axle tractor is equipment that is used in agriculture. How to assemble a tiller on a single-axle tractor and prepare the soil for sowing on your own personal plot?

A single-axle tractor is equipment that is designed to perform a variety of agricultural work.

It is necessary to get acquainted with the design of a motorized tractor beforehand, in order to perform its assembly in the shortest possible time. Most often, sabre blades and goosefoots are used for assembly. They are handy, so much of the work can be done without replacing the tiller. The result is less time and lower maintenance costs.

How to assemble a tiller for a power tiller

A single-axle tractor is an in-demand tool on the plot today. Assembly of the tiller for the power tiller is an important moment in preparation for tilling the ground. The most common cutters are sabre blades (image ), and devices called goosenecks (image ). These attachments are easily assembled on a power tiller. They do most of the agricultural work on the land. They only need to be replaced very seldom. This greatly reduces the time it takes to service a power tiller.

About the elements

They are needed when tilling the soil. The model therefore determines the quality of cultivation and the complexity of the procedure itself: the load on the motor, ease of operation and labor.

The power tiller is usually supplied with the crawler. But that may not be enough. Sometimes the depth or width of cultivation needs to be increased, so the unit can be supplemented with other products. This solution also improves the process of moving the tiller forward. This also increases the service life of the machine.

If the soil is clay, then it is better to use two pairs of tillers. And even if the soil is light and has already been worked before, the additional elements will not be a hindrance.

Changing the depth is possible thanks to the variable coulter. It is a solid element, which is located in the coupling of the motoblock vertically. The final ripping depth is influenced by the diameter of the rotary cultivator.

If there is a desire to make milling cutters for the power tiller with your own hands, you should start with the definition of their types. Two types of construction can be distinguished:

The last option is the most popular, it can be called a standard. After all, these types of products are time-tested: their effectiveness is quite high. They have the optimum shape and material. Knives are made of quality steel of high strength. Additionally, the material is thermally hardened and treated with high-frequency current.

It should be noted that tillers-cultivators have a collapsible design. Such a feature is caused by the fact that the material does not accept welding well. As a result before mounting the product on a single axle tractor it is necessary to pre-assemble it.

As for “goosefoot” products, such products are used for hard soils. They are of solid construction, non-disassembled. Thanks to this their strength is high.

Such products are effective in weed control and tillage. However, their disadvantage is the material of manufacture. carbon steel. This affects the strength of the products: therefore, it is necessary to process virgin soil very carefully, so as not to bend the product. Nevertheless, it allows firstly welding, and secondly repairing.

It should be noted that the cutter is a self-sharpening tool. No additional manipulation in this direction is required.

Technical characteristics

Advantages of the Celina NMB-603 power tiller from other manufacturers: reduced noise level and low amount of harmful substances in the exhaust. It is allowed to use the power tiller in public places: parks, gardens, dacha cooperatives.

The process of assembling a tiller

Two different shapes of blades are available:

• Sharpened. “Petals” easily enter the soil without grip. the engine loads are reduced and fuel consumption is cut. But the sharp blades do not remove the weeds completely, they soon sprout again. You need to work carefully with these canopies to avoid damaging plants and for your own safety;
• With a semi-circular edge. They are distinguished by their safety in operation. But there is more resistance when ripping, the tillers are more likely to get stuck. Such blades for cultivator cope with weeds more effectively.

There are two ways to attach “petals”:

• Riveted. The element is not dismountable. In this case, it is not very convenient to store and transport the device;
• On bolts. Can be disassembled.

To assemble the power tiller to your power tiller it is important to observe the correct direction. the sharpened portion of the tine should be in the direction of travel of the machine.

Number of sections equal to fixing plates: if they are all the same, only three elements can be installed. If they will shift, four to six sections should be mounted. Blades need to be pre-marked.

How the tiller is assembled?

• When mounting a three-blade burier, the first blade is fixed to the plate. the bolt does not need to be fully tightened at first. The two remaining knives are fixed on the opposite side of the plate;
• The right and left blades are alternately mounted on the four-blade and six-blade cutter. It’s worth separating the “blades” into right and left blades in advance;
• If necessary, the additional section is mounted with a pin;
• The design is bolted as rigidly as possible;
• At the end, a protective disk is attached to the shaft to protect the plants from damage.

Is it necessary to mill a single axle tractor??

There is no clear answer to this question. It all depends on the limitations of your power tiller, the soil and the conditions of use. For example, if you work on heavy soils with a power tiller and power tillers, sharpening is not necessary. You will not see any significant effect from this procedure, you will only waste time and effort.

For a lighter power tiller with small cutters, sharpening is not a bad option to improve the quality of work. But there are disadvantages, too. First, the sharpening only lasts a few hours, then the procedure will need to be repeated, which is a long and time-consuming process. Secondly, sharpened knives contribute to crushing the roots of weeds, and this, in turn, can only accelerate their reproduction.

If you do decide to sharpen the burrs, take them off your power tiller, clean them from the ground. Sharpen each cutting element with emery paper very carefully so as not to damage them.
