In several posts you refer to "safety" issues, but from re-reading this thread from the beginning I can't tell what you're referring to. What safety issue(s) are you referring to?
Is it correct that you are located in Northern Portugal? While I'm sure we're all flattered that you chose to post on TBN, I suspect there's not much anyone monitoring this site will be able to do to solve your problems. Have you considered finding a blog that is on the continent?
You clearly have some justifiable concerns. The root cause for these individual problems would be some combination of TYM corporate, your European distributor, or your local dealer. We only have the first of those in common with you.
The purpose of forums -this one is for world wide and not specific for USA - is not solve the problem each one has. It may help most of the times, but for that issued it is first needed to post public the problems that are not solved either by dealer, or later by manufacturer.This works as an alert to each visitor.
The "safety miscompliance" mentioned has been detected and confirmed by National Governmental Department of Agriculture through technical inspection performed under there responsability and protection of agricultures.
HST adjust is mentioned in TYM USA manual with owner responsability step by step trouble shooting, not worlwide. European and other country laws-same in USA, if ones search - , concerning safety of humans is direct responsability of manufacturer that must present each model manufactured for inspection, on hundreds parts, prior to release for market.
What can ones expect if representation assitance is not able to fix the failure? - you know what real pbl is: tractor do not stop movement when you
release both fw/bk pedals, neither you are able to place lever from H/L to Neutral position with engine runing - hst is always under pressure. Imagine you are attaching a FEL requiring inch by inch approche? Do you stop/start engine inch by inch movement?
You are correct when saying the only thing in common is TYM company. That is the real problem refused to be solved and that is also what a new TYM owner can expect if local dealer is not able-(lack of knowledge, missing spare parts...lack of quality...) - to solve because it overcomes his business agreement with TYM.
TYM Korea police is sell and keep profits leaving clients by there own.
