Hi all... Have a weird situation. Or at least to me it's weird. I have an old 36" bobcat. It works fine except a few days ago, it's extreme;y hard to turn to the left. I changed the belt, the spring. I made sure the pulleys were loose. and it seems like I don't have equal power. If I'm standing behind the mower, I have more power on the right than the left. Also, if i just let the mower go straight, it curves to the right. Any ideas???
