The Seasons mod is arguably one of the best mods currently available on Farming Simulator. Although some find it difficult to grasp it because there is a lot of additional work to be done. In addition, some tasks are repeated from year to year. Like snow clearing roads, long and tedious. For this kind of routine work, it is interesting to use Courseplay 6.
No there is no "snow removal" function, at least not yet, but nothing prevents you from traveling your roads, even by car, and from recording the race at the same time. You can proceed by zone, for example by creating a "snow removal fields 4, 5, 6" race. And why not create a hangar specially dedicated to this activity? With DDE tractors equipped with a blade and a salt spreader. Then nothing could be simpler, just load a previously created race, activate the tools (the courseplay does not manage the activities specific to the Seasons mod), and click on "start the race". We tested, we approved!
