LEMKEN, a company that specialises in arable farming has optimised its front hopper and coulter bar system, adding greater versatility to its range of seeding machines

The latest addition of the ISOBUS technology to the Solitair 23+ front hopper and OptiDisc 25 coulter bar ensures precise, convenient adjustment and optimal utilisation of the machine fleet.

The new technology allows adjustments to be made to the seeding rate or width section control, via the MegaDrill control on the tractor terminal. It takes strain off the operator, and ensures efficient use of consumables and seeding, without overlap of up to four width sections.

Combined with the rotary harrow Zirkon 12 and the OptiDisc 25 coulter bar, the Solitair 23+ front hopper forms a compact, agile drilling combination. This enables a better distribution of weight, compared to rear-mounted systems, allowing smaller tractors to be used for efficient drilling technology.

The front hopper is suitable for both seeds and fertiliser, and is therefore, ideal for sowing maize in combination with the Azurit precision seed drill.

In addition to the 4 metres and 4.5 metres folding versions, the OptiDisc 25 coulter bar will be available in three metres and four metres rigid, and five metres and six metres foldable versions. These new folding variants feature an additional transport system for road use. 

The transport support wheels take the load of up to 3.5 tonnes off the tractor’s rear axle, ensuring that the tractor’s maximum permissible axle load, and gross weight, are balanced. The additional transport system locks and unlocks easily. 

The parallelogram-controlled double disc coulters form the core of the OptiDisc 25 coulter bar and depth control rollers ensure seeds are placed precisely at the pre-set depth, with both mulch and conventional tillage. Also, coulter pressure can be mechanically or hydraulically adjusted independently of the seed depth. The Solitair 23+ front hopper is available now and the new OptiDisc 25 coulter bars will be available from January 2022.
