Just like the previous games from this series, Farming Simulator 19 also gives you the option to cut down and sell trees. A good way of doing that is to sow them and collect on your fields. You can also cut down trees that grow on your parcel. At the beginning of the game, you probably won't be interested in getting money by cutting trees - you will only want to get rid of them to have more space. The easiest way to do that is to go to the Shop and buy a chainsaw for $1,000.
