Hey guys. I'm new here and looking for some information. I have a 743 that was my dad's. I have had it for about 6 years now. I have replaced a head, radiator, and had the hydrostats rebuilt. It has 2500 hrs on it. I use it around the farm and sometimes do small jobs for others. I am just concerned that it is going g to dollar me with its age. So I am looking to upgrade. I have looked at the S185, S250, 873G, and T190. What is your opinion and what machine would you buy
