I run a small old fashioned farm. Yesterday I was mowing, hit a rock, and my sickle mower came unhinged. Literally. I think this is a feature of the sickle, when it hits something hard, it comes undone to not wreck it. I do not know how to reassemble it. I am flummoxed completely. Please help me. I am a long time reader, first time poster. Thanks!! I enclosed a couple pictures. I'm not sure if something broke off.
 
Picture did not show up. That said every time I have had that happen to a sickle bar mower all I did was carefully grab the bar at the end keeping my fingers out of the guards and sickle part and pull it back into place. Should have a place on it with a catch with a spring that it will snap back into

I used to just put the tractor in reverse and back the bar slowly into something solid, like a tree or stump.
Otherwise I'd get off the tractor and pull the bar forward until it latched into place again.
 
From your photo, it looks like it just kicked back like it's suppose too.
Give it a quick snap foreward when it's raised off the ground, it should latch....might need a little grease at the latch to help it slide into place.
 
Hard to say with out being able to see it. But if you look it over you should be able to tell if you broke a part off or if it is not going into place. You may have to loosen up a spring/nut to get it to pop back in
 
From the picture I would say your just not snapping it back in place hard enough for it to latch. I hate the idea of trying to back it up and using a tree etc to snap it back in place because if your foot slips off the clutch pedal etc you could end up with a big broken piece of scrap iron
 
That linkage looks like it hinges around and then snaps into the retainer. I don't think it slides. It may be locked slightly past center. Manually push it out toward the sickle side of the mower while pushing on the sickle bar. It should pivot around into place. Just going by what it looks like. I have Massey Ferguson and John Deere mowers and the breakaway is different.

From what I see,I agree with the others who say back up against something solid.The unpainted arm should snap behind the piece that the little chain is dangling in front of.I would smear grease on both pieces first.If it does not latch in place,get it close and swat it with a sledge hammer.Or get it close,and just unpin everything,and reassemble.
It is a safety feature,and is supposed to what it did,and it is supposed to go back.I would try some grease first.Mark.P.S.The rear most piece of the linkage appears to be bent,and that may be why it does not snap in place,because it is over centered.It MAY need to be bent straight.
 
Why not it over real close if something
broke off you should see the break. We
always had JD mowers and on ocasion we
would have place the bar in front of
something like a hay bale to get it to
snap back in. Just feather the clutch
when you do.
 
I can see the latch there by that chain. That latch should be spring loaded and a pretty stiff spring.The other part of the latch mechanism looks alright.The short arm should swing right around toward the rear tire and be held in the latch, unless the latch is busted and that chain is supposed to hold something
 
looks like a 3 pt. model so it would be a 451.all you need to do is raise it up pull the cutter bar back and and give it a good push forward done it lots of times should snap right back in. don't back it against anything because it makes it bind and will not snap back in.
 
I backed into a tree and fixed it good. Thanks all for your help. Much appreciated. This is my new favorite site.
