John Deere tractor with wood and haycart trailer Discover the new John Deere CONSTRUCTION Line. Build your own John Deere 6215 R tractor in a scale of approx. 1:24. Take the chassis, mount the tyres, the seat, the driver's cabin and the engine bonnet. Do you want to use the front loader to load the bales of hay onto the hay cart? Mount the hay cart attachment on your trailer. Or do you want to transport wood? Then convert the trailer into a wood transporter. Don't forget the counterweight on the front of the tractor.
