Lime spreading – first operation after harvesting

Acidification of the soil is a continuous process on which we could have no influence as farmers.

Acidification is caused by: calcium washing out, acid rain, usage of nitrogen fertilizers or the process of raising calcium together with crops. The correct pH of the soil has a measurable impact on better harvest and lower expenses on mineral fertilization. The first step before entering the field should examination of the soil in the nearest District Agricultural Chemistry Station and determination of its pH rate. The correct reaction for different soils differs according to its agronomic category. Lime spreading best to perform just after the harvest is finished, it means in the autumn. The lime dose should be determined based on the results of our soil analysis. It is most preferable to lime every year in smaller doses.

As a manufacturer of agricultural machinery we have a wide range of machines used for lime spreading.

The series of RCW spreaders have been known among farmers already for over 40 years. The RCW trailed spreaders are universal machines which are used for spreading lime and mineral fertilizer. The wide range of spreaders and different options allows to make even a small machine as a multifunctional and efficient unit that finds its customers among medium sized farms as well as large agricultural holdings and companies providing agricultural services. The newest and the biggest model right now is RCW 120, which is characterized by a large hopper, single-axle chassis, wide tires and sprung shock-absorption of drawbar.

UNIA RCW 120

Another way to distribute efficiently lime on large surfaces is to use a manure spreader equipped with a horizontal-&-disk adapter. The biggest model in our offer is TYTAN 36 spreader with horizontal 3-shaft adapter and with spreading discs. The machine has got 3-axle chassis. In order to improve comfort and safety of work the chassis in standard is equipped with 1st and 3d steering axles. Axles has got shock-absorption by means of spring suspension. In standard equipment the bottom drawbar is suspended on the leaf spring. TYTAN 36 has got two floor conveyors that move in parallel to one another. Each conveyor consists of two coil chains connected by scraping strips.

In standard equipment the machine has got a hydraulically lifted tailgate which separates the hopper from the adapter, so that when starting the spreader loaded material does not push on the adapter shafts, allowing for smooth start and even spreading of material from the beginning of operation. During lime spreading the manure load should be reduced by the percentage of closing of the tailgate, e.g. the tailgate is closed halfway, the load capacity of the spreader should be reduced by approx. 35% as the lime while driving on the road/field forms hardly divisible body. Loading of material into the spreader should be performed starting from the rear part to the front of the hopper, as it positively affects the quality of the later spreading process. It is desirable to distribute the spreading material evenly across the entire surface of the spreader hopper

Time for aftercrop seeding ...

After harvest many farmers decide to seed aftercrop. It can be done in several ways, but it is best to use special seed drills.

UNIA – has got in its offer two solutions for aftercrop sowing: mechanical ALFA model and pneumatic ETA.

ALFA can be used both for seeds sowing as well as for spreading of fertilizer to width of 2,2 up to 4,0 m. The seed drill is available for assembling on tillage tools and in the front suspension configuration to the tractor. ALFA is equipped with so-called "fuzer" sowing apparatus where the dose is adjusted by pulling the shaft on which the apparatus is mounted. Some models are offered with a guide bar that affects the accuracy of seeds distribution. ALFA seeders use the spur wheel as a drive device. ALFA's great advantage is the range of assembling attachments for various machines: skimming units, disc harrows, grain seeders (grass sowing), or version for tractor front linkage (fertilizer spreading).

ETA pneumatic seeders are offered with 200 or 500 liters tanks and are especially recommended for mounting on cultivating machines, which are hydraulically folded to transport position. Seeder allows to distribute seeds up to 12 m wide. The dispenser and blower drive can be hydraulic or electric depending on the size of tank and the size of machine on which this unit is mounted. ETA 500 hydraulic seeder can be equipped with 8 or 16 scatterers (recommended for width over 7m). The seeder can be controlled by two types of computers: TYPE 3.2 (standard) is responsible for constant seeds distribution at a certain speed; and another one - TYP 5.2 – optional equipment -   with a speed sensor allows for uniform dosage of seeds regardless of speed.

We kindly encourage you to get acquainted with details of our aftercrop seeders offer.

New FENIX 3000/6

FENIX 3000/6 semi-mounted combined cultivator and seed drill

 Cultivator

A front-mounted drag with spring arms ended with replaceable tips evens the soil surface in front of the disc section and removes the traces left by the tractor wheels. The approach angle of arms towards the soil is controlled mechanically by means of turnbuckles.

Behind the drag, there are two rows of toNew FENIX 3000/6othed discs known from ARES units, having a diameter of 460 mm. The discs are manufactured at the largest UNIA factory in Grudziądz. Each disc is protected by rubber shock absorbers and has double-row maintenance-free bearings, which ensures comfortable work without the need for lubrication.

The working tools used in FENIX 3000/6 has been designed and manufactured by Unia Grudziądz based on many years of manufacturing and operational experience – says Michał Stachlewski, Commercial Director at UNIA.

The spacing of the disc rows is as wide as 82 cm. This allows you to work on fields with large amounts of crop residues, e.g. in the case of maize harvested for grain. Combined with the working speed of 15 km/h, perfect covering of crop residues is guaranteed. With such a high working speed, massive, profiled side deflectors play an important role by preventing the soil from getting beyond the unit’s work area.

The working depth of the discs can be adjusted even during FENIX 3000/6’s operation from the driver’s cab by controlling the operation of hydraulic cylinders. The whole system is based on an independent suspension of the disc section on a parallelogram.

Behind the cultivation disc section, a tyre roller is mounted. – A special, unique design of the tyre roller ensures optimum agrotechnical conditions for sowing. At the same time, thanks to four wheels with a size of 500/45–22.5 and a diameter of 1,040 mm, the comfort and safety of transport on public roads is much higher. The remaining tyre roller wheels have a diameter of 800 mm and are used only during the unit operation. Optimum adjustment of the tyre roller to soil conditions is aided by individually set hydraulic cylinders with an individual setpoint – says Sławomir Jaskuła, Product Manager at UNIA.

 

Seed drill

UNIA FENIX 3000/6 combined cultivator and seed drill has 40 double-disc coulters with a diameter of 300 mm mounted in a “V.” Behind them, there are very large ground-following and pressing wheels with a diameter of 350 mm and a width of 78 mm, which make it possible to set the drilling depth very precisely. The time required to change the working depth of all 40 coulters is less than 5 minutes. The coulter pressure is changed centrally via hydraulic cylinders.

Large ground-following and pressing wheels also provide very good following of ground bumps. Thanks to that, the seeds are placed at a desired depth and have optimum contact with the soil. The coulters are pressed by a strong spring, which translates into a constant minimum pressure of 40 kg per each coulter. It does not decrease even at high working speed of 15 km/h – says Sławomir Jaskuła, Product Manager at UNIA.

The spacing of the disc coulters is 15 cm. Such a large distance between the coulters allows you to work on fields with large amounts of crop residues and in stony soils.

Behind the double-disc coulters with ground-following and pressing wheels, individual spring scrapers are mounted to rake the soil from the interrows, leaving minidepressions. Water, which is scarce on many European fields, may accumulate there. Each set of stripper fingers has its individual screw adjustment.

UNIA FENIX 3000/6 combined cultivator and seed drill has massive hydraulic side markers which fold quickly along the machine. This solution makes it easy to drive on public roads and to fold the machine to the transport position.

Precise pneumatic sowing

UNIA FENIX 3000/6 combined cultivator and seed drill has a large grain tank with a capacity of 3,000 l. This minimises the time intervals between subsequent charges and thus increases sowing efficiency. The tank can be accessed using a platform ladder located at the front of the machine. Thanks to the tank frame, the tarpaulin protecting the tank interior against moisture can be easily unrolled. Inside the tank, there are robust screens on which a large BIG BAG can be placed.

At the bottom of the tank, there are two chutes through which the seeds go to two sowing devices. These precision components are driven by an electric motor controlled by a radar sensor which reads the exact unit speed in the field and makes the sowing independent of the wheel slip. The electric drive of sowing devices also makes it possible to quickly and easily change the sowing rate, even during operation. There are no problems with carrying out a calibration test at stops as you simply enter the relevant data into a computer, place a seed container and press the button on the drill.

UNIA FENIX 3000/6 combined cultivator and seed drill is capable of sowing seeds in kg/ha rates. During sowing, the rate can be either increased or decreased from the computer desktop by tapping the plus or minus symbol, which each time means changing the rate by a fixed percentage value.

Precision row sowing following conventional, simplified or direct tillage is carried out by means of a pneumatic sowing system using state-of-the-art sowing devices. Two grain distributors ensure highly uniform drilling in all coulters. In order to sow fine seeds, it is enough to lock the sowing roller filler using a small lever, which takes only a moment – says Sławomir Jaskuła, Product Manager at UNIA.

The seeds are transported to the coulters by a fan driven by a hydraulic motor with an oil flow of 24 l/min. It is powered by a pump placed on the tractor PTO. The independent hydraulic system of FENIX 3000/6 also includes a radiator with a thermostat and an oil tank with a level indicator and a temperature sensor. The air pressure in the sowing system is controlled by a pressure gauge visible from the driver’s cab.

The grain collected from the tank by two sowing devices goes into separate systems where it is carried away by the air generated by the fan. This way, seeds go to the distributors. As the seed drill is divided into two 3-metre sections, it is possible to carry out sowing using only half of the drill – all you have to do is close one of the sowing devices.

Wires to all 40 coulters come out from the left and the right distributor, 20 wires from each of them. Each distributor has Combi valves for automatic sowing interruption mounted on two wires for the purpose of setting up tramlines. The stopped grain goes back to the distributor and thus the number of seeds in a single row is increased. However, it is possible to apply a percentage decrease in the sowing rate using a computer, so that the fixed rate of seeds per hectare remains unchanged after stopping the sowing in two coulters.

Müller Elektronik computer

UNIA FENIX 3000/6 combined cultivator and seed drill is equipped with a Müller Elektronik computer called DRILL CONTROL. It has the following features:

  • processes the speed data transmitted by the radar, thus maintaining an unchanged rate of seeds per hectare regardless of the wheel slip,
  • sets up tramlines,
  • informs the user about the rate of sown seeds in kg/ha,
  • counts the covered hectares and the amount of sown seeds – field history records,
  • informs the user about the seed level in the tank and triggers the low-level alarm,
  • makes it possible to prepare the sowing devices for the calibration test at a stop – it is enough to enter the necessary data.

The E-DRIVE function allows you to change the sowing rate during sowing! This very useful system comes in handy when setting up tramlines or working on mosaic fields. The sowing rate can be either increased or decreased by tapping the plus or minus symbol, which each time means changing the rate by a fixed percentage value.

UNIA FENIX 3000/6 combined cultivator and seed drill is equipped with a set of hydraulic solenoid valves controlled by the UniControl controller which supports the automatics of hydraulic systems involving the sequential operation of their circuits. It is enough to press a button and the machine unfolds or folds itself. It may also automatically change the position of markers at the headlands.

Transport on public roads

UNIA FENIX 3000/6 can be driven on public roads. After the field work, the side wheels of the shaft as well as the cultivation and sowing disc units are hydraulically folded to the vertical position. Thanks to that, the transport width does not exceed 3 m.

After folding, the machine is based on four very wide road wheels which ensure high stability during transport, even on poor quality dirt roads.

UNIA FENIX 3000/6 has a number of additional protective features allowing a completely safe transport on public roads. These are:

  • mechanical transport locks of hydraulic cylinders,
  • pneumatic dual-circuit brakes as standard,
  • professional road lighting meeting the current standards.
