Hi KC: I would recommend making a purchase of the operators manual from one of the dealers. You can find them top right under members. It's nice to have a bound copy and I have one for all three of my GTs. Additionally, please refer to the Technical Library:
viewforum.php?f=24 which contains most of the service, parts, accessories and operators manuals for the these fine tractors. Also see changing oil in the hydraulic system, go to the second page of the FAQs, by clicking page 2 on bottom right. If you are contemplating changing any bad hydraulic lines or fittings, this is the time. The dealers should be able to supply any hydraulic lines you may need. You will find that all that oil adds up to a few bucks $$$.
