#5 sickle bar mower

The "bellcrank", "adjusting screw" and "turnbuckle" are all located at the rear of the cutterbar inner shoe, just inboard of the cutterbar.

I hope this is understandable. Pictures would help, but my scanner is "down" at the moment.

Sounds like the bow is gone from your bar. Needs to be resprung.

The cutter bar tends to 'bow down' over it's length in time due to gravity and it's own weight. So, what happens is, that you go to lift it and it will end up pointing to the ground out at the far end.

To couteract this effect, the bar must be bowed upward across it's entire length.

I always had the John Deere dealer do it for me in the spring, but it is really no big deal. It needs just enough bow so that the bar lays fairly flat when lowered to the ground and when you drop the bar, the center should always touch down first.

However, imagine if you were to stand that bar up on it's edge, it should have quite a drastic "bow" or "C" to it in the direction of the top face of the bar.

In other words, when lifted, the bar should come up fairly straight. If it bows down, it needs attention. Of course, 9' bars are more demanding than the 7 footers.

Hope this makes sense.

Never heard of such a thing as having to spring a cutter bar or have it rebowed or whatever. I would think if the inner shoe lifts and the outer shoe doesnt then some adjustments need to be made on the lifting mechanism. But its been5+ years since I run a mower.

We had to re-bow every mower we ever had on a yearly basis. 'Course they were long barred devils and we were dealing with heavy irrigated alfalfa all the time too. :>)
