Hello Everyone, My dad passed away a couple of months ago. He had a MTD Lawn Mower tractor that is about 15 years old. The front tire is flat but I am not sure how to pump it up. It does not have a tube so I am not sure what to do. I was going to take the tire off but I don't know how to do that. Should I do?! Thank you very much!!

Have you looked on the inside part of the rim? The valve stem will be located on some units to the inside. And if you don't see the stem, chances are you do indeed have a tube and the stem has gone inside the tire.
