How to find all collectibles in Farming Simulator 22 (location)

Like previous games in the series, Farming Simulator 22 has 100 collectibles to discover. These are toys like vehicles, animals and so on. For finding each collectible item you will receive $1000. If you collect 10 items of the same category, you will earn $100,000.

The screenshot below shows the locations of all collectibles in Farming Simulator 22:

And this is what one of the items looks like (a toy blue tractor):

The location of some items is less obvious. For example, collectibles #11 and #12 are inside a building that, at first glance, is impossible to get into. And collectibles 24, 25, 26 and 27 are hidden in the caves. Others may nahwalk right out in the open. Like the tractor from the picture above.
