First let me say this post is not directed at you...it's directed at the topic. The point you make an all-too-often made point that is based on wishful thinking. What "causes" parts to "become readily available"? Nothing. Parts do not "become" anything. Someone, some business entity, undertakes the design and manufacture of a part, or line of parts, and then there are parts available on the market. Businesses do this to make a profit. That means they have to expect to sell enough to cover the design, start-up, and production costs AND get a good return on the capital invested, all in a reasonable time frame.
It is very expensive to set up the manufacture of a given part. Start up costs are labor & design intensive. There has got to be reasonable assurance of a profit, and that is dependent, among other things, on the size of your market. To my knowledge there is only one business currently having any significant amount of aftermarket parts made for Yanmars, and those parts are for YM models (unless by chance they also fit Fs) because of the number out there. I have some knowledge of the costs involved in the development of some of these parts, and they are in some cases staggering. There are plenty of YMs left in Japan. Until there are a large enough number of Fs in this country to justify the HUGE investment to get parts made, it is not going to happen. Dealers who sell Fs and maintain good parts resource for their customers get most of those parts from Japan.
They all tend to be good tractors, and there are seldom breakdowns, but it is going to be a long time, if ever, before F and FX parts are as available as YM parts.
