Regular blocking of footpath

This vehicle parks here multiple times per day completely blocking the footpath and depending on how well parked the road as well as the trailer sticks out. Yesterday when driving past a mother with 2 young children had to walk on the road to pass. Today I had to do the same. A wheelchair user would be really stuck! This is a daily occurrence. The owner who I assume is tending to his sheep just needs to park in the field which he is parked outside.
