photo of my NH 477 sickle knife end

Here is a better way to ask my previous question. I bought new knives, and got at pounding out the rivets and got them all off and now its put back together point and I question my sequence of how to rivet on the knife head assembly to the knife back. My parts manual does not make it clear for me either. My question is length, how long should the sickle bar extend past the last guard? You can see in my photo that at the farthest reach, it does stick out quite a way now that I have it back together. I do not remember the sequence to align the two pieces for joining. This is what I came to but I question it, it seems unguarded.

Any help, please fire in there.

I assume you have the blade fastened to the wobble box. If so and if your pic shows the blade at the end of its stroke, I think you have it right. If you have the blade fastened up and you can turn it slowly without anything hitting something it shouldn't, then you have it assembled correctly and you can try it under power, slowly at first.

If you removed only the knife sections I don't see how you could assemble it wrong anyway. I only used a NH469 but I think the assembly would be the same. You have the half knife on right and the rest should be no problem. Hope this helps.

I think I got out of confidence when I popped every rivet and had two pieces in my hand. So I had lost my nerve to how to bolt it back together. You can align those holes in a number of combinations to get a number of different lengths overall.

Then it seemed odd that it stuck out that far unguarded after I gambled and put it back together how I thought it would be.

Now I have seen a pusher bar to push the crop away from the end to keep it from grabing hay and gumming up.

I would think it be as simple as lining up the last knife in the last guard, rotating the woble box to it furthest position that way and measuring the lenght needed (match up holes). Then swing woble box back the other way, pull last knife to the second to last guard, and verifing the measurement.
