Disk harrows «Rumba», production of disk harrows

Production of disk harrows «Rumba»

Trailing and mounted disc harrows (disk headers) «Rumba», two disc row harrows

Plant «Kubanzheldormash» is the main manufacturer of disc harrows in Russia and in the countries of the former Soviet Union, our harrows for disk harrowing make it possible to effectively cultivate the soil, chop crop residues, chop perennial grasses, fallow and virgin lands. Disk harrows «Rumba» are designed for loosening the soil, destruction of weeds, grinding and embedding of crop residues. They are made in two-row, three-row and four-row versions. The original design of the harrow provides floating and forced modes of penetration of the working bodies. It is possible to change the approach angle of the working bodies in the range from 0 to 25⁰. The distance between the disks (not less than 27 cm) is the maximum allowable convergence to avoid clogging the space between the disks. Harrow has spring-loaded rollers, each of which can be adjusted as the depth, and increasing/reducing the pressure on the agricultural background. The frame design provides a copy of the relief of each section of the disk harrow.

We produce:

• all types and kinds of disc harrows for tillage, working width from 1 to 6 meters
• depth of cultivation from 4 to 15 cm
• optional press wheel of different configuration (slatted, spiral or spiral-shaped, slatted-spiral, serrated, combined, single row, tandem, etc.)
• for tractors with power from 40 to 560 hp.

The advantages of disc harrow «Rumba» produced by «Kubanzheldormash»

• The strength of the frame structure, which is achieved not only by proper engineering calculations of the pipe section, but also by the use of high-strength steel 09G2S

Interminable controversy: disc harrow or pre-plant cultivator?

Design of disc harrow, transportation of disc harrow

Disk harrows «Rumba» have a simple and reliable design, which facilitates the maintenance of harrows in the field conditions. Powerful reinforced frame with a margin of safety, made of structural steel is manufactured using the most modern welding equipment and materials. We use only the most modern welding equipment Kemppi (Finland) and ESAB (Sweden). The design of the disk harrow can already be considered as established, it is not much different from different manufacturers. Smooth, often toothed BMD disks «Romashka», collected in the battery, located at an angle to the direction of movement of the unit. When moving the harrow, the disks begin to rotate and crash into the layers of the soil, thereby starting to loosen, mix and roll the soil aside. When they change the disk approach angle, they can adjust the depth of cultivation. On disc harrows «Rumba», the depth of processing is easily and affordably adjustable. An important distinction of our harrows is the fact that each working body can be quickly replaced; even the mechanic himself can do this, it is enough to have a spare disk and a metalworking tool. All materials used in the manufacture of disc harrows in our company, have quality certificates and are in-plant input control using the most modern laboratory equipment, which allows doing metallography, measure the physical and mechanical properties, to conduct spectral and chemical analysis of the metal structure. Disk harrow «Rumba» has a hydraulic system (fittings, quick connects, high-pressure hoses, hydraulic cylinders) which ensures its folding into the transport position.

Folding scheme «butterfly» is the most convenient and effective for transportation when folded. The arrangement of the rollers eliminates «fail patches» when working harrows on any agricultural background. In the folding harrow, the half-wings redistribute the load at the expense of the spacer spring mounted on the frame. Due to these technical solutions, the harrow works perfectly both on «dips» and on «hills» (with vertical differences). Adjustment of the depth of processing is done by the lanyard (optionally, the lanyard can be replaced with a hydraulic cylinder), rollers and changes in disk approach angle (in the case of work without rollers). Harrows of the Rumba series ideally, with an accuracy of up to 5 mm for the full width of the grip, keep the geometry at the expense of the design developed by us. The harrow in its class refers to the average, since the load on the working body is 85 kg.

The use of disc harrows in agriculture, the right choice of harrows, the necessary options, maintenance, reviews

When choosing a disk harrow, it is necessary to understand for what purposes it will be used, on what soil and in what modes to use, what results are expected from tillage. Today in tillage, disc harrows are used in three cases – shallow treatment (pre-plant treatment to a depth of 6-7 cm and peeling after cereals), medium-deep treatment (mixing, grinding and cutting of plant mass and weeds to a depth of 7 to 14 cm) and deep treatment (mixing, grinding and cutting of many weeds and plant mass to a depth of 7 to 20 cm). For all types of tillage, different types of tools are used, which differ from each other in such parameters as the diameter and thickness of the disk, the shape of the disk, the type of attachment to the supporting frame, the type of location, the disk approach angle, the presence of different types of rollers, the width of the harrow, the row and so on. For peeling stubble after cereals it makes no sense to buy expensive and productive heavy disc harrows, for these tasks it is quite easy harrow. 

A very important criterion when choosing a disk harrow is the working width.

 It is very important to take into account not only the technical characteristics of your traction equipment, but also the area that you are going to handle. In such cases, standard data are usually taken into account, but all farms have different soil and climatic conditions, different requirements for cultivation, so always consider your personal experience and the experience of your colleagues in the region. The easiest choice is listed here:

• Farms up to 500 Ha – optimal working width from 2.4 to 4.2 meters
• Farms up to 1000 Ha – optimal width from 5.2 to 8.2 meters
• Farms from 1000 to 1,500 Ha – optimal width from 8.2 to 10.2 meters
• Farms from 1500 Ha – optimal width from 10.2 to 14.2 meters.

Important! The main error in the operation of disk harrows

 Disc harrow is an agricultural tool that can do almost anything in the field, except turn in place in a working position; when working bodies are immersed in soil, only straight-line movement is allowed. To make a U-turning the harrow it must be moved to the transport position. Unfortunately, such an error with pressure for the production capacity occurs in machine operators very often, which leads to increased load on the frame, to wear of the working bodies and bearings, to the failure of the rollers. Excess speed affects negatively. If you want the disc harrow to operate long and without breakdowns, try to adhere to the optimal speed of disking-12-14 km/h Also, one should always bear in mind that disc harrows are not suitable for working on stony soils, since the blades are very quickly destroyed (break off).
