At this point, with noone reading the thread called "dwdave" in the JD section, I would NOT respond to this post anymore but rather start a new post in the New Holland section and use a more informative subject line... which most people look at and will "catch" someone's eye. Something like "Help with TC35D No Hydraulics" Make sure to repost the fact that you tried what was listed here.
It seems that the tractor has few hours, any chance that it's covered under a warranty from a dealer? or did you buy this used?
