Solitair NT

Sowing is decisive – for yield, soil health and farm success.

LEMKEN offers all farmers a practical solution that adapts flexibly to the various forms of cultivation – from conventional cultivation methods to conservation tillage methods up to direct seeding. You can depend on: 

•  Precision – for smooth crop emergence and optimal plant development
•  Adaptability – for changing conditions, cultures and processes
•  Efficiency – through high working width and operating speed
•  Comfort – through intuitive operation and easy adjustment
•  Reliability – thanks to robust, low-maintenance and long-lasting technology

Row cleaner

The downward angle of the seed coulter and the row cleaner help minimize the hair-pinning – where plant residues and other materials are pressed into the seed slot. The integrated parking position for the row cleaner is unique: If the field conditions change, the row cleaners can be locked by a tool-free adjustment.

ProDisc single-disc coulter

The six disc with ten degrees downward angle and an angle of seven degrees to the direction of travel ensures a minimum requirement for tractive force and prevents soil compaction in the seed placement area. At the same time, it guarantees safe opening of the seed furrow with the LEMKEN ProDisc seed coulter – high coulter pressures are only necessary in extreme conditions due to the easy penetration into the soil. The seeding depth can be freely chosen between zero and ten centimetres. The depth is adjusted without tools via a preloaded lever for each seed coulter. 

Closing roller

The final step on the way to the perfect crop emergence is the closing of the seed furrow. For absolute flexibility under all operating conditions, both the pressure and angle of the locking roller can be adjusted without tools. An aggressive angle position and a high pressure of the closing roller guarantee the best work results even in very dry conditions.

It’s all in the metering

Even the basic version of the Solitair NT comes with four fertiliser-proof metering units per tank or half tank respectively, each of which supplies one distributor with seed – a prerequisite for manual width section control, which can also be controlled automatically via Section Control as an option.

Ready for every type of seed

The size and weight of the seeds of different crop species and of different types of fertiliser can vary greatly. Standard and fine seed wheels are therefore available for the various crops. To change the seed wheel, the seed wheel area can be easily separated from the seed hopper using a slider. This allows the seed wheel to be replaced or cleaned even with a full seed container. The coloured marking on the handle clearly identifies which seed wheel is fitted.

Axle lift

Due to the axle lift, the ground clearance is also increased. This means that even the steepest field entrances are not a problem for the Solitair NT.

Parking position

If the field conditions change, the row cleaners can be locked by a tool-free adjustment. They are then in the shadow of the coulter mounting.

Filling auger

In order to help load seed into the hopper, a hydraulically swivelling filling auger is available, which is integrated into the Solitair NT.

Impact plate

If the component is to be applied from the MultiHub to the soil surface, application via the impact plate is recommended. For this purpose, it is transported from the hydraulically driven blower to the two distributors of the impact plates. 

Hydraulic track markers

 The hydraulic track markers are centrally located and always in the driver’s field of vision. The hydraulic overload protection makes working as comfortable as possible even under difficult conditions.

Tramlines for crop maintenance

An integrated hydraulic tramline mechanism is optionally available for the ProDisc seed coulters. The symmetrical distribution of the seed tubes ensures absolutely even transverse distribution even in tramline mode. The seed rate is automatically reduced when the tramline is activated. Changing the distributor cartridges is easy, ensuring quick adaptation to different tramline systems, which greatly increases the flexibility of the machine – especially when it is used on multiple farms

Separate width section control

The Multi-boom function can be used to automate the control of separate width sections for fertiliser and seed. This prevents overlaps. It is also possible to process three application maps in parallel so that seed and fertiliser are only applied where they can be used efficiently

Numerous possibilities for the calibration test

The calibration test can be carried out either directly on the machine or via the iQblue software solution on the tractor terminal or a smartphone.

Precisely calibrated

The Solitair NT offers numerous variants for the seeding locations of the individual components, which are easily selectable at the push of a button. Four dosing wheels per container and two dosing units on the MultiHub create maximum flexibility. The component from the MultiHub can be applied, for example, via the impact plate, but also via one or both rows of coulters. This allows you to react flexibly and in the shortest possible time to the different conditions

No tillage seeding

The Solitair NT also plays to its strengths in direct seeding. The 10-degree downward angle ensures active soil grip and reliable penetration of the seed coulter – even under dry or solidified conditions. The closing roller, which can be adjusted in pressure and angle, specifically restores the soil closure, promotes capillarity and ensures a quick, even emergence. The machine runs smoothly in the lane, keeps the depth and enables precise row guidance even at higher travel speeds. This enables the establishment without pre-seeding soil cultivation – safely and efficiently.
