Solitair DT

Can be optimally adjusted to the tyre width and penetration depth, regardless of the working depth of the Heliodor section. The iQ drill control with integrated headland management takes care of the raising and lowering processes at the headland.

For crumbling and levelling the seedbed and for reconsolidation ahead of the disc section.

Reliably level any unevenness when used on ploughed land and can be easily adjusted from the tractor seat. For the best possible work results, the levelling tines can be used in grade or drag position.

With a diameter of 465 mm and a thickness of 5 mm, these ensure good penetration into the soil, even in the most difficult conditions.

For less intensive soil mixing, the 22-mm corrugated discs have a waveform shape. These discs are particularly suitable where the germination of weeds is to be suppressed. In dry regions, corrugated discs allow water- saving seedbed preparation because only the area in front of the seeding coulters is loosened. The use of corrugated discs reduces tractive force requirements even further.

The high-quality axial angular ball bearings ensure lasting, flawless function of the discs. The bearings are completely encapsulated so that no dirt can penetrate.

The fertiliser coulter bar is located in front of the tyre packer roller. Fertiliser is precisely placed at the desired depth with up to 150 kg share pressure via the double disc coulters (400 mm diameter). The depth at which the fertiliser is placed is adjusted via clips on the hydraulic cylinder. When seeding without under-root fertilisation, the fertiliser bar remains in the elevated position in order to protect the fertiliser coulters against wear.

Flexible adjustment: For optimal placement of two different types of seeds or for simultaneous inter-row fertilisation, the drilling depth can be adjusted via the fertiliser coulter bar.

Single-shot: The fertiliser and seeds or two types of seeds are placed in a shared seed furrow.

The double-shot version places the fertiliser or second type of seeds in a line below the seedbed via separate double disc coulters.

The generously dimensioned tyre packer roller with a 90-cm diameter ensures even reconsolidation across the full seedbed. The staggered arrangement of the individual wheels additionally leads to better self-cleaning and ensures good sowing, even in wet conditions.

With an additional harrow between the tyre packer roller and the seeding coulters, the seedbed can be optimally levelled.

As an alternative to a harrow, a trapeze packer roller (420 mm diameter) can be added to the Solitair DT to obtain a defined pre-consolidation of rows directly in front of the OptiDisc double disc coulters. The roller improves both the smooth operation of the seeding coulters and the soil contact of seeds.

The Solitair DT is equipped with the maintenance-free OptiDisc coulter bar. This bar boasts parallelogram-controlled double disc coulters and trailing depth control rollers.

Seeds are pressed into the soil by the depth control roller to ensure even, rapid field emergence. Both coulter pressure and seed depth can be adjusted independently of each other. This ensures that seeds are always placed at exactly the same depth, even at high forward speeds and in changing soils.

The coulter system is available in a hydraulic version (up to 70 kg coulter pressure) and a mechanical version (up to 45 kg coulter pressure). The row spacing is optionally 12.5 cm or 16.7 cm.

Four distribution heads positioned directly above the coulter bar ensure superior transverse distribution.(Image1: Distributor in sowing mode).

An integrated hydraulic tramline mechanism is optionally available for the OptiDisc (image 2: distributor with switches tramlines). The symmetrical distribution of the seed tubes in tramline mode ensures that no seeds need to be returned. The seed rate is automatically reduced when the tramline is switched. The easy exchange of the distributor cartridges enables quick adaptation to a wide variety of tramline systems. This increases flexibility – especially when working across farms.

Whether for calibration testing, adjustment or cleaning – the corrosion-resistant metering system is easily accessible.

Metering is 100% fertiliser-compatible. The tool-free seed wheel change allows a fast switching between different seeds.

This allows width section control even in the basic version. Automatic width section control is optionally available.

The speed signal for metering can be from either a radar sensor on the drawbar or the speed signal of the tractor.

MultiBoom supports automatic, separate width section control for fertiliser and seeds. This prevents overlaps. It is also possible to work through two application maps in parallel, so that seeds and fertiliser are only applied where they can be used efficiently.

Using the layout manager, the user interfaces can be freely configured and saved in up to four driver profiles. The system is controlled either via a LEMKEN CCI-1200 terminal or via any universal ISOBUS terminal.

The information menu gives access to various diagnostic options. The new diagnostics system guides operators directly to the source of any errors in case of disruptions and assists them in troubleshooting.

For good levelling and coverage of seeds, the levelling harrow and single harrow, which can be adjusted without tools, perfectly complement the double disc coulters. The S levelling harrow is adjusted via a pin, which allows the harrow height and harrow pressure to be adjusted independently of each other. The harrow can additionally be fitted with hydraulic lifting to facilitate transport and precision cultivation. The single harrow reliably covers two seed rows and therefore adapts to a wide range of conditions.

The Solitair DT is optionally available with a pre-emergence marker to mark the tramline as it is created. This marker is automatically lowered when a tramline is created. Hydraulic

The hydraulic track markers are centrally located and always in the driver’s field of vision.

The tank is conveniently drained via a drainage valve on the side of the machine.

The speed of the hydraulically driven fan is infinitely variable and is achieved even at low tractor engine speeds. The oil requirement is only 30 l/min. Variations in the tractor engine speed do not affect the speed of the fan to ensure the consistent, even delivery of seeds.

The Solitair DT features a long drawbar for maximum manoeuvrability when working with wide rear wheels or twin tyres. This allows a steering angle of up to 90 degrees, even with a maximum outside tractor width of 4 m.
