The spring loaded idler pulley has to be pushed away (up) from the belt.
Turning the pulley will also help roll it into the groove of the pulley.
Then when you let it back down it will go on and let it will tension the belt.
I’m only concerned with the rod/linkage in my picture as the one on the side of the transmission is straight.
the picture from the parts boo looks like it has a bend at the threads, but I think that’s a bad idea too.
I am not sure if my 4wd linkage is bent or not. I am leaning towards it’s not bent based the two attached pictures.
If not bent it’s an adjustment issue.
Can anyone verify by looking at there linkage and say if mine looks okay or not?
My son was mowing a pasture today and noticed a sound like a ratcheting noise when the 4wd lever was riding a bit forward in the disengaged position and abated when move further rearward.
I found a post that mentioned the same type of sound, but know outcome was posted...
Here’s the Ford type knife I referred to the John Deere version is similar.

I think all Y-blade knives are reversible, but there are other knives that aren’t they typically have a cutting surface that is parallel to the ground.
My Ford 917, Bushhog flail and John Deere flails all use this type of knives. However, they can use Y-blades too.
