The Pittman bar broke on my 501 sickle mower, and I didn't pay good attention when I dismantled it from the sickle portion. Now I can't seem to get it back properly. The long side pieces are curved - should the curve go up from the ground or down towards the ground? How far from the "stop" near the ball should the ball be when attaching? If anyone could post some pictures, that would be great! Thanks in advance.
