If a lady was saying my lawn mower debris hit her car, is it worth appealing?

Lady stopped and said I hit her car 5 minutes ago while I was mowing and she heard a big bang. Showed me 2 little scratches on the rear bumper and said she'd have to ask her husband if they were there before. The scratches were only through the first layer of clear-coat at a 45 degree angle pointing towards the base of the tire. I told her she ran over something and the scratches would be sideways not at a 45 degree angle. She brought her husband back and he ask if I had Homeowners insurance. I told him no. I told him he's going to get scratches like that on his bumper. He said "I know". We went to small claims court and the judge said he didn't know what the law was. He asked the plaintiffs who their relatives were and said he would go in his chambers and research the law. After about 1 minute, he emerged and said I lost. I think he flipped a coin. I have the right to appeal. The lady never seen anything coming out of my mower and I think she would have had more damage moving at 35-40 mph. Is this case worth appealing?
