I have an old rusted out implement that my grandfather had. Not sure what it is. Looks like you could attach it to a trailer ball. It has semicircular spikes on the back. I tried moving it and the semicircular things do move but then they stop and the left wheel stops rolling as well. Not sure if it is working properly though as it is so old. Definitely would not be able to adjust some things such as pins do to the rust. Any ideas would be appreciated.
