May I drive tractors class L private !?

Hello,it is about a tractor,but for the sake of driver’s license I think that the truckers here have more idea of what to drive and what not. There is the driver’s license B, which also includes class L for tractors and up to 32 km/h and trailers up to 25 km/h. So far so good,if you can drive,but there is something about forestry and agricultural purposes and construction reasons. Does that mean you can only drive this team if you work in an agricultural business ? U nd how is the private ? Because you will also move an old tractor up to 32 km/h or ? Possibly with trailer ? So I don’t go through there anymore, hope it can help someone with information.
