LEMKEN Solitair pneumatic seed drill„

DS seed depth adjustment. The sowing depth and coulter pressure can be adjusted independently, ensuring precise seed placement, especially in varying soil conditions. The position of the press wheel relative to the double disc coulter, and thus the sowing depth, can be easily changed by turning the coulter bar with two screws.

Access for calibration check. Use the fold-down step to easily reach the calibration tray.

Multiple dosing. The 6-section cellular rotors can be switched on and off as required for different types of seeds, so there is no need to change the shaft when switching to another type of seed. A consistent seed flow is always achieved by adjusting the volume and speed. The standard „Solitair“ has two or four metering units depending on the width.

Hydraulically powered fan. The fan is hydraulically driven with infinitely variable speed control. This requires only 20.4 l/min of oil flow. The required speed is achieved even at low tractor engine speeds. Fluctuations in tractor engine speed do not affect fan speed. Seed flow always remains constant.

External distributors. The seed distributors are located on the outside of the seed hopper, directly above the coulter shaft. The seed tubes, which run from the distributor to the coulter, are of uniform length to ensure that the seeds are distributed evenly. The angle of the seed tubes is fixed to prevent blockages. The distributor can be easily opened for inspection. For spelt sowing, spelt distributors can be ordered as an optional extra.

Compact design. „Solitair seed drills form a compact combination with a tillage implement.

Width section control. Each dispenser can be individually switched on and off mechanically. This function can optionally be controlled from the tractor cab using the „Solitair“ control unit. This ensures that the remaining area is sown without significant overlaps.

Mechanism of technological progress. On the „Solitair“ seed drill, up to 2 x 5 seed tubes can be fitted with tramline mechanisms for forming individual tramlines. Due to the automatic switching of the tramline valves, the air pressure in the system remains constant. Uniform seed distribution is also guaranteed by the switchable tramlines. When forming tramlines, the seeds are returned to the seed hopper.

Seed bunker emptying function. The seed hopper can be easily emptied via the drain valve located on top of the hopper. Any remaining smaller seeds can simply be discharged via the calibration tray.

„Solitair 8+“

• „The Solitair 8+ pneumatic seed drill is equipped with a mechanical drive. The metering system is driven by a maintenance-free cardan shaft and a stepless gearbox, ensuring that the perforated rotors in the metering unit are driven evenly. The star wheel rotates within the working width of the implement – this ensures a constant, even driving force.
• The stepless gearbox allows for precise adjustment of sowing rates from 0.5 to 500 kg/ha. It covers the entire working width without any additional adjustment to the drive section. A fine-graded scale from 0 to 150 ensures the required precision. The sowing shaft operates smoothly to ensure that the seeds are distributed evenly along its length. This is particularly important when the sowing rate is low and the sowing shaft rotates slowly.

„Solitair 9+“

• Both the Solitair 9+ seed hopper and the lid feature a new design. The plastic hopper lid fits securely but is easy to open thanks to a gas strut. The lid opens to a wide angle, making it easy to fill the hopper even with big bags. A hopper with a capacity of up to 1,850 litres is available as an option. Using this reduces set-up time and increases productivity.
• The roller rotates between the two seed furrows within the width of the seed drill, so it always remains on the pre-tilled surface and the drive remains constant. Once the work is complete, it can be easily folded away with a single movement of the hand, without the need for any tools.
• An optional radar sensor is available for highly accurate speed measurement with no margin of error.
