I just purchased an older Dixon ZTR zero turn mower. It has a serial number of 45-021471 on the left side of the frame in the back by the engine. It has a 15.5 hp Briggs & Stratton Vanguard motor. Serial number range online seems to say that this mower was from 1987, however, I cannot seem to find a picture of the exact model. It has a deck serial number of DK 13579. I cannot get the light to work on it. I am looking for a manual but as I don't know the Dixon model number. If anyone can assist, I would appreciate it. Thank you in advance.
