Wallner was showing this straw harrow with a slight difference at Agritechnica. As well as four or five rows of 16mm tines, customers can add a knife chopping roller along the front of the harrow, which comes in working widths of 3.0, 4.8, 6.0, 7.2 and 9.0m.If the tines are not doing enough work, they can be fitted with a top hat attachment that increases the contact area. The pictured 9.0m model carries a price tag of €18,500 with the chopping roller costing €880 per metre. An air seeder is also offered.
