Hello all, this is my first post. I've got a hydraulic problem that I wonder if anyone might have some input on. Trying to buy my uncle's old '54 D6, which looks to be in suprisingly good shape. Once I fixed a fuel/carb issue with the pony motor, I got it fired up (after it had been sitting a year) and the diesel ran very smooth. However, I couldn't get the hydraulics to raise, although they did push down somewhat, lifting the front slightly. I'd be interested if anyone had any ideas. On pre-check, the fluid levels all looked good, and no visible leaks anywhere. BTW: It had been parked with the blade resting on the ground.
