Weird Problem?

[Mr Jimi]

I have a factory manual for my Case 1845C and sometimes when I back-up it feels like the brakes are grabbing on the left side? To my knowledge, there are no brakes on my unit? I opened the chain cases and added some oil and I don't think thats the problem? They feel like they are dragging not locked up.

Well I still have the same problem, I can go forward a little and it feels like it releases? I don't know if it does but it acts like it does, any ideas .
