Not sure if this will help.

My Haban sickle bar was designed for your tractor. I retrofitted it on a 416H. Because I used the hydraulic lift, I moved the gearbox over about an inch. The tensioner arm is unchanged except for making the shaft longer to line up with my PTO. On mine the belt is very very close to the housing rod, yours should have more room. I connected the spring to floorboard rod, not sure where yours would connect to.

Thanks for the information.  So I was wondering how did you made yours work on the hydraulic lift?

I made a pivot bar that slides in a U-block. Its attached the lift chain from the pivot arm that's controlled by the hydraulics. The driveshaft was in the way so I moved the gearbox, shaft and pulley over 1". The gearbox that came with the sickle bar was worn out inside (gear and pinion). I found a NOS gearbox for a Ford 2-stage thrower. Exact same gearbox except the output shaft splines were different. So I had to make the first half of the driveshaft. You can tell by the new paint in the photo. The whole unit pivots around the mounting pipe that hangs from the tractors front pivot arm to the rear axle hanger.
