| As far as the ram, the measurements from center to center of the pins is 20 1/4" closed and 28 1/4" fully extended, so 8" of throw on it. The pitman arm wood is 1 1/8" by 1 3/4" stock and 25 3/4 long. It is notched on the one end for the brackets that go to the sickle side so it is only 1 1/2" wide. The other end has a hole bored into the end for the spring to set into. I don't know how deep it is without taking the spring out. From the center of the most inside holes on each of the brackets is 15 1/2". As you can see in the pictures, the brackets are turned 90 degrees from each other. I hope that helps Carl and others that needed the info. If you have any other questions, post them here or PM me and I can try to help you out. |

| Carl, I have a manual for mine around here someplace, but I can't find it right now. When I get home from work, I will look in there and see if there's anything that will help you. |

If you are having trouble cutting with a sickle bar mower you may check the stroke. The sickle blade should move from the center of one guard and end on the center of the other. If the pitman rod is the wrong length that will cause the blade to be out of time and will not cut properly.
I sold a customer the wrong pitman one time and he messed up a field of mowing. He was nice about it but my father was not that nice to me. Be certain about the pitman rod wood length. It is critical.
Good Luck!

| The hole for the spring only goes in to the first cross bolt so its about 3/4" deep. I replaced mine a couple years ago. We just made it out of a Oak piece to match the original. |
