The GST for an old tractor is about 25 percent, so now count the full price when buying or selling an old tractor. By the way, when I was still buying used tractors, the GST was about 18-20 percent, but that was about 10 years ago, so times are changing, and
the same tractor that I bought 10 years ago, I would now buy much cheaper. Well, this is my business. I hope my post will help you in your affairs. If you have any questions, then write to me in private messages. Good luck to you, my friend, see ya.
