|Is there a part number on the main sickle bar itself? My bar is 7/16" thick made from 1piece of steel. Yours looks like a single piece as well. The bar in the manual is made of 2 thin plates sandwiched together which makes it cheaper. The holes can be stamped vs what I'll bet are drilled on ours. I'm thinking that ours may be older than '74. My fingers are singles 3" centers vs the doubles you have on.|
I'm thinking that the total bar thickness of the 2 thin ones is less than 7/16. A previous owner, needed fingers, saw the same parts list, and replaced the single fingers that were on it with the doubles shown on the parts list. The problem is that the parts list is not for the bar we have. Maybe someone has a double bar SBM that could measure its overall thickness to confirm my theory.

I have a sickle bar mower mystery. I liked Dean Stuckmann's idea of a front mounted SBM and was able to locally find a mid mount Haban from a cub cadet and make a similar rig to Dean's. I got it set up according to the Haban manual that he sent me(which happens to be for a cub cadet) all except for the way the cutters lay on the shear fingers. With proper hold down clip clearance of 1/32'' they nearly touch at the tips and have 1/8''+ clearance at the base . I figured someone had put the wrong fingers on at some time but it is the right Haban part# 6732 . So I figured that must be the way they intended it to fit. Looking at the manual again I see the part where it says " check the top surface of the wear plate with the top surface of the shear finger, these must be even". In order to make those even I would have to have fingers with about 1/8'' more offset, or bend the finger in two places to create more offset. Doing a good job of bending would be a challenge and the fact that it is the right part# makes me wonder just what is going on. So I thought I would put it out to the group for ideas. I have done some mowing and it does work but I really need to stay in LL or I clog the cutters. Dean says he can mow in L and his cutters are set the way I think they should be not with a big gap at the base. I will include two links to picassa photos of the rig and the cutter. I think it will be a very useful tool once I get it dialed in.
