Most tractors have one side of the 3pt is adjustable up and down, always center up with the top link and then hook up the opposite side of the adjustable lift arm first. Then check to see how close the lift arm is on that adjustable side, it may only need to be turned up or down, if it needs to go forward or back, a bar can sometimes be used in the tail wheel to just twist it one way or the other and aid in hook up. The main thing is to save your back and not hurt your self.
