I recently bought land that had a Ford 3000 in the barn. The previous owner told me to keep it. I do not know the exact year model it is, or if that matters. But I'm usually mechanically savvy and I got it to crank and idle okay at about 16-1800 rpms after changing the oil and putting new fuel filters on and also cleaning the air intake. It will run in all gears in high and low. My only problem is that after about 10 minutes of running good, it struggles once it gets put under a load such as going up a hill. I've even got a bush hog and attached that and attempted to cut down some tall grass, it does great for 10 minutes then it wants to bog down. All 3 injectors have fuel making it to the cylinders and the injection pump has a good return to the tank. I just do not know where to look from here on out.
