Does a person who has life estate to a property have the right to remove personal property from that land that belongs to the heirs of that property?

My father has life estate to the family farm. My mother passed away and he is remarried. The farm was signed over years ago to myself and my siblings. I had a vehicle sitting on the property and my father and his wife decided they did not want it there and called a junk yard and had them pick it up and scrapped. Do they have the legal right to make that decision when it was not their vehicle and my dad only has life estate rights.
