The rotary harrow HR3004 from the manufacturer Kuhn is mainly used for seedbed preparation. Optimally, you can combine them with, for example, the Amazone D8 30, or the specially modified Kuhn BTF3000, also found here in the section "Mods". If you saddle them in conjunction with the Kuhn BTF3000, you need a front tank or a seed wagon in the front, to visually complete the team offers here the seed wagon TF 1512 from Kuhn;)
