Scale 1/50 Agricultural trailers look exactly like this when they are realistic: the New Holland T pulls the brightly coloured silage trailer into the Farmer 1:50 scale programme! . The chunky tractor has a drawbar giving the trailer great manoeuvrability. The silage trailer?s rear flap opens to simulate realistic loading jobs. . The trailer is fully compatible with the expanding world of SIKU Farmer and SIKU Super 1:50 scale die-cast models..
