Well, it seems that a little drifting on grades is normal with a HST.

I did ask the dealer when I went to pick up my tooth bar and extra backhoe bucket this afternoon. He said about the same as everyone here. Some slight drifting is normal.

When you have an idea in your head it pays to ask about it. I asked, and have to thank you all for helping to settle my mind.

Perhaps this thread will help another newbie like me in the future. I hope so!

Thanks again!

Bill
