I actually do have one tire that always slowly looses air, I repressure them all equal before each cut, I need to get the tire/rim/whatever is causing it to lose air fixed too!
My MTD can barely turn left, the turning radius is HUGE because of this. I can't find any obvious adjustments or bent rods. Right turns are fine, but not very desirable as it throws grass into the uncut part of the yard. Advice?
