I run a 36' MacDon draper on an R75 and I have trouble spreading straw in wheat and soybeans the full width of the header. I see in the parts book that a double spreader is offered. I've never seen one installed on a Gleaner. Does anyone have any experience good or bad? Looks like it throws the straw both directions. I'm not talking chaff spreader here as I already have a double chaff spreder installed.
