Something stinks in this story and I think its the dealership. 1) Contact the Police and file a report on the stolen mower and the shop. 2) Contact a lawyer and have a letter sent to the shop stating your intentions. Sitting back and wishing is not going to get anything done action is what is needed. It may cost you a few dollars but why let them get away with something like this. If they didn't do it themselves I bet their going to get reimburse by their insurance company for your lost mower. I say fight it don't let them bully you.
