If you have tillage left talk with your dealer and see if you could try a 9RX, I bet you would own it after 1 round.  I'm not putting down any brands I'm just making an observation that I didn't realize would be such a problem. I knew by reading on here that it would be an issue, but not to the extent that it ended up being because you couldn't even use it.   I love the tractor otherwise, it's got awesome power and a nice ride and the cab is like the other Deere's I have.  I just wished it would turn under a little load.
