I have thought about the turning and decided for my uses it would be straight shots with minor wiggling. If I really planned on turning a lot, I would put the tow bars back on. It really is solid the way I have it set up, surprisingly. I haven't tried to load it up simply because the Bolens 1250 doesn't have a float setting (dang it!). If I had a three point on the HT-18 I would definitely load some weight on it and let it float with the terrain. I will put some weight on it and see how it does this weekend. Also, I may put some angles on that go from the top link to the corners if I need more support. Regarding the tires, I like them on for depth control, but If I need to get into tighter spaces, they will come off. I'm planning on aerating yards on the side, so to fit in back gates, they made need to come off.
