I need to replace my mower deck on my TG1860 and it's an RCK48TG (48")model. Does anyone know what present day compatible deck will fit this application? I have called two dealers on this and they won't call me back. If I could find out the compatible model, maybe I could get some help from them. I guess they don't want to look this info up and make a sale of a new mower deck... Or perhaps, there's not a replacement deck... Please help!!!
