I bought this used to cut my 20 acre yard. (I bought this to replace my older IS3000z.) At first, I thought the 3100 just had sensitive steering which I thought I could easily adjust. But NO! It darts uncontrollably especially on a slight incline. It seems to get even worse at it warms up. I feel like I'm trying to steer a darting bull around the yard. It's nerve wracking. Any suggestions where to pinpoint my problem? I've had 3 different commercial zero turns and I could figure out any problem over the years. I just don't know where to start with this. So....motorheads....give me your suggestions.
