First thanks to everyone who responded to my earlier question on PTO HP. I am considering two different tractors (Ford 3930 or an Agco Allis/White 5650(made by SLH for Agco)) and since I will not use the tractor alot each year and my work will be generally light; I expect that either will last me a lot of years. I have read some posts that talk about manufactures discontinuing parts after a few years. Since my tractor will not get much use parts availability maybe something I want to consider in making a choice. What is it like getting parts 20-25 years down the road? Does brand make a difference is Ford/NH or Agco different? Does the fact one tractor is made in the US and the other is imported make a different since they are both sold by major names? I sure would appreciate your comments on this issue.
