I have started to notice a lack of responsiveness in steering my BX 2200. FYI I now have 175 hours on it. It seems to wander a bit when mowing. Just noticed it the last two times I cut grass. If I attempt to make just a small correction, the steering does not respond. I took it out on the street, flat and smooth, and it does the same thing, slow or no response until I move the steering wheel about 1/2 turn. Anybody have any ideas or suggestions?
