Adjust the centers of the holes to be concentric and well-aligned before attempting to push the pin through.

Drive the pin through. Fit the washer and the nut. The nut takes a 30mm wrench. Do not over tighten, just snug.
Use a screwdriver, or something that will fit through the hole in the round head to keep the pin from turning.

The top spring arm will fit onto the top cap as shown. Again, do not over-tighten as it needs to be able to pivot.
Before removing the bolt from the top cap, raise the three point hitch on the tractor and cut a 2 foot length of
2x4 to support the lower arm. Let the three point hitch down so it is resting on the 2x4. This way the pin will not
fall out of the hole when the hardware is removed on the top.
