Ok I'm a neubie on this site so be nice. I have a BX2230 my problem is when raising my deck the right side is going up higher than the left side. When mowing the left side mows lower then the right side. Main problem is when raised the right side now scrubs the rear drive wheel. Any help would be appriciated on what to look for or to adjust. I noticed the left arm is loose not much but the nut is backed off about an 1/8 of an inch, toward the deck. Thanks in advance.
