I own a 523Dxi with a 52" deck and it's my first season using it. It's an awesome machine, but I need it go a bit faster, especially when it comes to turning. I understand (or think I do) that it's designed to slow sharply on turns to prevent it from tipping. Is that correct? But it seem to slow to much. It's faster to just back up, cut the wheel, realign and cut a new row. Any suggestions on increasing the overall speed a bit? THX
