Need trailers to transport potatoes and cereals but ideally something that only weighs 4.5t empty which is a big ask I know but if you don’t ask you don’t get. Have a 13t Norton trailer that was new in 1993 and although only lightly built is still in use. So if you are only using the trailer for carrying crops and not rubble and soil do they need to be built like a tank and is the extra strength unnecessary?
