Maestro CVWITH AIRVAC SYSTEM – PRECISE – VERSATILE

AirVac – the new generation of vacuum singulation

The AirVac metering device can be used universally for an exact grain singulation. Due to different metering discs, maize, sunflowers, sugarbeet, soybeans and rape can be singulated reliably.

The AirVac system is based on the principle of vacuum singulation where the seed is sucked to a perforated disc. During the metering process the accepted grains pass through a scraper that sees to it that doubles are removed. The special feature of the AirVac scraper is that the user does not have to carry out any adjustment works. The contour of the scraper has been optimised in such a way that a reliable singulation for all crops is guaranteed.

Via a fall tube the AirVac metering device leads the seed to the bottom of the furrow. A grain sensor is integrated into the fall tube to guarantee an optimum monitoring of the seeding success. The measuring technology of the sensor is able to count the grains, to determine the spacings between the grains and thus also to transmit an information to the driver with regard to double spots or gaps.

The transmitted values of the singulation accuracy are displayed clearly at the terminal of the machine and additionally increase safety while sowing.

The AirVac singulator is driven electrically as a standard and each row can be controlled individually. This technology co-operates with the well-proven functions single row switch-off, SectionControl, VariableRate and tramline control.

For VariableRate the AirVac system is designed in such a way that the seed rate can be modified for every single row. With the tramline control it is possible to individually adapt the seed rate in the row at the left and the right side of the tramline. With these advanced functions all measures to increase precising while sowing can be used to full capacity.

Maestro CVTHE COMPACT MIDDLE CLASS

The compact Maestro CV unit that consists of a high-capacity seed wagon and a seed bar for a working width of up to 7.2 m provides high efficiency whereas the demands on the tractor are comparatively low.

To meet the requirements of the customers in an optimum was, two configurations of the seed wagon of the Maestro CV are available:

Single hopper for fertiliser

The hopper with a capacity of 3 000 liter is used for applying fertiliser via the coulters of the underground fertilisation system. In this case, the seed is supplied in the large single row boxes with a capacity of 70 liter.

Double hopper for fertiliser and seed

The new double hopper system MTS (Main Tank Supply) can store 3 000 liter of fertiliser and 800 liter of seed. By means of the MTS technology the seed is continuously transported to the individual row units and then singulated by the AirVac metering device. The huge advantage of MTS is the simple filling of the central seed hopper and the simultaneous singulation of the seed on the row with a short distance to the seed furrow.

The fertiliser hopper of both versions is equipped with the well-proven HORSCH metering technology and can reliably and precisely feed the underground fertilisation system of the Maestro.

The coulter attachment of the Maestro CV can be equipeed with 8-rows and 9-rows with a row spacing of 70 / 75 and 80 cm. When used with 12 rows the row spacings amount to 45 and 50 cm. In the future, the newly developed clamping profile will allow for an easy changeover from 12 to 8 rows.

The row body of the Maestro CV is equipped with a wide, solid parallelogram and a hydraulic cylinder to generate coulter pressure as a standard. Coulter pressures up to 350 kg per row can be adjusted manually at the terminal or fully automatically with the innovative coulter pressure regulation system HORSCH AutoForce. The weight of the seed wagon is used to generate coulter pressure over the whole width of the machine and thus, relieves the wheels of the seed wagon while sowing.

AutoForceAUTOMATIC COULTER PRESSURE CONTROL

AutoForce – What do you need an automatic coulter pressure control for?

― Stony soils require more coulter pressure to place the seed at a consistent depth. If the coulter pressure is too low the coulter body would not move smoothly and the seed would germinate irregularly and with different speed.

― Lighter soils or more easily compacted soils require less coulter pressure to avoid a compaction of the soil. Too much coulter pressure compacts the soil and slows down the development of the roots although all seed was placed at the same depth.

― There rarely are fields that are regular. The coulter pressure should be adjusted for every section of the field.

― This is why HORSCH developed an automatic coulter pressure control system.

How does AutoForce work?

― There are 1, 2 or 4 sections over the whole working width of the machine.

― The system controls the pressure of the cylinders at the parallelogram and corrects the adjustments in such a way that the weight on the support wheels always remains the same. This is possible due to the design of the Maestro that allows for transferring weight to the seed bar.

― The coulter pressure then varies automatically between 125 kg and 300 kg.

Press wheelsFOR A BETTER EMBEDDING OF THE GRAINS

Which press wheel is suitable for which use?

― The finger wheel is ideal for heavy soils.

― The spike wheel is ideal for lighter sites.

― The rubber closing wheels are ideal for light sandy sites.

― If the furrow wall gets compacted because of the double disc seed coulters, it is broken by the finger / spike wheel – the furrow is removed.

― Seed furrow is not opened after sowing under dry conditions, especially on heavy clayey sites

― Development of the maize root is encouraged

― There is one finger / spike wheel and one standard wheel per row to control the depth and to avoid moving the grains.

― However, the wheels are not suitable for shallow sowing.

Optimum pressure – optimum sowing depth Too much pressure –too much compaction

Too little pressure –too shallow sowing

Optimum pressure –optimum sowing depth

AutoForce pressure sensor: Weight recording is carried out via Piezo (pressure sensor) technology.

MultiControl

When using a HORSCH Touch 800 / 1200 terminal you can also use the MultiControl function. If SectionControl is activated, MultiControl allows for switching on and off seed and fertiliser independently. If sowing is carried out in a site-specifi c way with VariableRate, MultiControl varies the quantity of fertiliser and seed independently. Without MultiControl, SectionControl allows for either switching on and off either seed or fertiliser at the right time respectively VariableRate allows for varying either seed or fertiliser.

HORSCH Intelligence

The machines of the future co-operate actively and HORSCH Intelligence allows for it. With intelligent software and electronic solutions HORSCH machines work even more effi ciently and help you to save money and nerves.

HORSCH technology is always equipped with ISOBUS standard. This does not only mean that every HORSCH machine can be controlled with any ISOBUS terminal. In addition, every HORSCH machine with a job computer can, as a standard, carry out functions like SectionControl, VariableRate or the order processing with the TaskController as soon as the necessary licences have been activated.

VariableRate

ISOBUS VariableRate allows for a site-specifi c application of seed and fertiliser. Thus, with an appropriate application card for every section within a fi eld the optimum quantity of fertiliser and seed can be applied.

Advantages of VariableRate

― Saving of seed and fertiliser as only the necessary quantity is applied

― Homogeneous emergence with an optimum number of grains/m²

― Simple and quick documentation– The different application rates are documented automatically.– Uncomplicated transmission to the acreage index

― Reduced stress for the driver– Fields are drilled or fertilised automatically with the optimum application rate

― Protection of the environment– Only the necessary amount of fertiliser is applied.

VariableRate also takes different typres of soil into consideration.

TaskController

The ISOBUS TaskController allows for easily transferring data from the PC to the terminal. It also is possible to transfer and document seed rates, sown hectares and other data that were recorded while sowing from the terminal to the PC. This facilitates the administration of the acreage index. Orders can be created and worked off via the integrated order handling management.

Advantages of the TaskController

― Uncomplicated data exchange

― Automatic documentation

― Structured working due to data management

― Simple administration of the acreage index

― Simple accounting and proof for contract services

SectionControl

The ISOBUS SectionControl function allows for an automatic section control. The current position of the machine is deter-mined via GPS. At the fi eld boundaries, on the headlands or near obstacles, sections (individual row switch-off) or the whole working width are switched off automatically and thus overlapping is avoided.

Advantages of SectionControl

― Saving of seed and fertiliser as overlapping is reduced to a minimum.

― Constant working quality on the whole fi eld

― Productivity increase under various conditions (day and night, fog)

― Reduced stress for the driver

― Protection of the environment

WITHOUT SectionControl WITH SectionControl Variable Rate allows for applying site-specifi c quantities of fertiliser and seed by means of application maps.
