I think this is quite normal in country’s that have white winters the farmer clears the roads and everybody chips in. The tractor isn’t doing a lot at this time of year and he gets to make a few bob to pay for the attachment that fits on his tractor. All they have to do is stop people parking in the road so he can get through.
UK law can you be prosecuted if somebody skids off the road because you have cleared it??? Bit like clearing the pavement in front of your house.
