Need help please
 

I have a cub 128 and my rock shaft arms are not level. in other words, my deck is unlevel becuase my passenger side arm is lower then the arm on the left so the deck is 3inches high on the left and 1 inch high on the right when all the way lifted up. The deck is adjusted evenly its just that right arm that hangs lower then the left side.

So i took the middle cover off and noticed the roll pins in the shaft. they are both in and secure. the right roll pin is signinficanlty larger then the left side though. the left roll pin is lined up directly top center while the right arm is not top center actually leaning more towards the front of the tractor.

Should i knock the pin out and see if i cn adjust the arms back to level?

I would yes. Jut because you see the roll pin doesn't mean the middle isn't broken and clocked differently, I've seen it a lot. Although there's a chance that side is bent I would go there first

Welcome to OCC Tyler,

Chances are you have a sheared spiral pin in one of the arms. It will be difficult to get out, you must line the holes up and then drive the broken pieces out.

Good Luck with it.
