I have a d200 that has one brake peddle and it does nothing. I was told it was a parking brake and I was better off leaving it that way since if something on the inside broke it could mess up my transmission, The linkage is connected but I haven't a clue as to why it isn't doing something. But taking it one more step I saw where the d200 also came out with a dual brake sys. and would like to know if I could economically convert mine and a recommended site as to where to get the needed parts.P.S. This is a working tractor that is in use. Not a show tractor. I would at some point be interested in putting a loader on it as well. Please for conveyance if you don't mind send me a response by e-mail jrrmcpk9@gmail.com
