Some of our roads/firebreaks are so curvy that I use the inside brake to get through. Guess this makes the inside discs 'dig in ' and I wind up with a banked road. Any way to prevent this? Thanks!

Disc must be level side-to-side. Raise the front gangs up some and let the rear gangs pull the dirt back in. Less severe turns would help if you can. If you use the left brake going one way, I'd think you'd be using the right brake coming back ????

Thanks Dr Allis. I can try lowering the back gangs with the top link. Have to negotiate around trees in quite a few places and I do use the inside brake both ways. Not that big of deal but a level road would be nice
I'll check my lift arms too.
