Decided it was about time I had some workshop time. So some more done to the sickle bar.
Mounted the assembly bracket and rod, to the rear and that shows it was not meant to fit a long frame Wheel Horse.
A custom mule drive is to be made.
Now the lift threw up more problems. The lift arm is longer of course and fouled against the assembly frame. I did take a photo, but it seems to have gone a.w.o.l.
After much fiddling, trying and changing, I've ended up with this.
Arm lift chain was moved forward and a fresh hole drilled in the arm to take the chain in photo. With gearbox and cutter bar fitted, which are not light by any means, there is just clearance between arm and frame.
Another problem then reared its head. The tractor the sickle bar is meant for, doesn't have foot plates. The C-81 does. The lift lever that raises the cutter bar upright, fouls the foot plate. So another will have to be made.
So that's it so far. Next thing is to separate cutter bar and gearbox again. Make things easier to handle.
