Very easy to combine it with the other cargo items available from Brio, see here: Brio 33570 Freight truck with trailer and the similarly constructed parts. The inner wooden boxes can also be filled into the silo, as they have the same degree, also from the Brio 33566 Kipplore can fill the black part. So you can not just "farmers" play but just use this Silo as a storeroom for all parts, the truck or the train with the empty wagons make topsy if it is correct, it does fall exactly on it and you can go on. My son gets the not so good back (just two years has become) but I think with a little practice and the years he will manage it.
That's the beauty of Brio, the parts count on to that Bale also a magnet, so that we can also make use of the existing crane etc.. Something more interaction very!
