Looking at trading balers.If anyone has a NH 330, NH 340, CIH LB334, or CIH LB434 baler, could you please reply with your experience with them? We are looking at one with the rotor cutter. I see there is a bumper option, what is this? Has anyone tried either of the accumulators? Has anyone tried to use it with a JD 2630 display? TIA
