The swing arm N6202 may be installed on the series BNE,VKD,BNU,BNG,BP series 10,BV series 10/100 allowing the mulchers to work very gently and agilely between rows without damaging the bark or husk of young, fragile plants. Blade integrity for harsh terrain is ensured by the wide rotor oscillation range: thanks to an exclusive return system on the mulcher, the rotor remains within the edge of the tractor.
