Using this BRUDER tractor and trailer set is a breeze. First, if you want to attach the front loader, just make sure it's properly connected to the tractor. To load the bales onto the trailer, you can easily access it thanks to the folding edge rails. When it comes to moving around, the steering wheel extension and oscillating axle will help you navigate smoothly. For storage, keep it in a dry place to avoid any damage. If you notice dirt on the tractor or trailer, use a soft cloth to wipe it clean. Don't use any harsh chemicals as they might damage the paint or plastic parts. Also, when attaching or detaching the wheels, do it gently to prevent any breakage. Enjoy hours of fun with this set and let your imagination run wild on your farm adventures!
