In response to my issue with the TR75 combine, when i start the machine the hose that connects the pump to the reservoir gets sucked in and no hydraulics will work, i ordered a new dipstick, put it in but still have the same problem, i removed the dipstick, started it back up and still the same problem. I honestly don't know where to go from here, if for some reason the machine has too much hydraulic fluid could that cause my issue? The combine worked great a month ago, i started it a couple weeks ago and this issue popped up, guess the old gleaner will have to harvest some this year!
