Lemken has developed the first ISObus compatible version of its Solitair 23+ front hopper, and the working width of the rear OptiDisc 25 coulter bar system has been increased to 6.0m.

ISObus allows the seeding rate or section width control to be changed via the MegaDrill control on the tractor terminal, which says Lemken, helps to eliminate overlaps.

In addition to the existing 4.0m and 4.5m folding versions, the OptiDisc 25 coulter bar is now available in 3.0m and 4.0m rigid and 5.0m and 6.0m folding versions.

The additional road transport support wheels on the new folding variants take up to 3.5t off the tractor’s rear axle to ensure it complies with maximum permissible axle load and gross weight. The additional transport system is said to lock and unlock in just a few steps.

Combined with the Zirkon 12 power harrow and the OptiDisc 25 coulter bar, the Solitair 23+ front hopper is suitable for both seed and fertiliser and can be used for maize in combination with the Azurit precision drill.
