You started your rant in post #3. You said you knew Husqvarna did not have any service manuals before you started the thread. After I told you there were no manuals available, at that point you went off on Husqvarna and others for not producing what YOU WANT. I don’t know what being an engineer has to do with your argument, but being an instructor in this field and just about the same age, plus working in this industry for 50+ years, I do know that what you want may not be available. I also taught my students that, “If you may get mad at the answer, don’t ask the question “. So I’ll repeat the answer I gave before you started your rant. THERE ARE NO MANUALS AVAILABLE.
If you re-read my post carefully, I said Husqvarna does not offer service manuals, This could be for any number of reasons- not enough demand, hassle in producing, forcing customers to their sanctioned repair shops, liability for incorrect information, whatever; their call. However, that does NOT mean there are no service manuals legally AVAILABLE just because Husqvarna chooses not to sell them now.
I NEVER said I knew this at the time of purchase, as I clearly did NOT. Nor does it mean it would be illegal to obtain one. In fact I did NOT buy my ZTR "... knowing no manual was available" as you so incorrectly and unfairly stated. (BTW my "rant" as you characterized it in your second post was in my post #2, not #3.)
My being an engineer and patent lawyer is relevant as being in a technical profession all my life I know the general availability (or not) of service manuals for a wide variety of items. It is by no means uncommon to obtain them.
And of course you completely ignored in your last post the main reason I was compelled to respond to your post, e.g. your libelous unfounded and highly insulting, unnecessary attack on my character in your stated belief that I was seeking to incite a service tech to "... break with his warranty agreement". How could I being doing so if I don't even know what the warranty agreement is... Sorry I ran into your last post in checking my others in the hopes of my real interest in solving the ZTR problem, not responding to you. I'm sure you are very helpful on this forum with your experience and perhaps your time would be better spent helping them.
