I have been looking at a 1989 Zetor model 6245 that is for sale.I'm trying to figure out what some of the main problems this tractor might have.Right now the lights and some of the other assoc. don't work this could be a easy fix or is this a problem with the model.Theres not a lot of information that I can find on this model. The hours on the tractor are 2880.It looks like parts can be had?
