High work rates and first-class sowing performance: with these outstanding features the Avant01 folding seed drill combinations prove their specific strength, especially in farm overlapping operations. In larger working widths of 4 m or 5 m , the professional end user can profit from the modular build design. The front linkage of the tractor is sensibly made use of by the seed hopper. Additional weights are not necessary. So, with the seed hopper mounted on the front and the rotary cultivator, packer roller and sowing coulters on the rear of the tractor, the result is a manoeuvrable combination with an optimum weight distribution that provides high outputs even in small fields.
