The best of the Bruder toys we've purchased so far!!! I can't believe this has survived falling off the kitchen table, falling off my son's lap in the car into the foot well, etc, etc, etc!!! There isn't a mark on it and nothing has been broken off, so very very 4-year-old proof!!! There is lots to keep him interested on this tractor - opening doors, steerable wheels, opening bonnet, height-adjustable tow bar, removable front weight, etc. He has 8 wheels on his to make it extra special and is one of his pride-of-place toys!
