Yes, Jinman that is a brand new TC35D. It will stay in Brenham for maintenance when the TL goes to the Hill Country to tackle a lot more Cedar and Shin Oak - probably after the Winter (such as it is down here). The problem out in the Hill Country with Cedar is, once you cut it down, if you don't plant grass and keep the area cut, the Shin Oak pop up and become just as impenetrable as the Cedar were. And with all the rocks, it is difficult to get grass in and maintain it. Even a little Cedar sucks a lot a water out of the ground and as they get thick, nothing grows under them and you have erosion problems. There are some fields that are suitable for planting, but lots of hillsides with very little topsoil. Even if you save all the non-cedars and big, old cedars you still may not have enought trees in places so you have to pick your battles.
Back to that ring under the joystick, I've never used mine. Do I understand correctly that if you grab the ring and lift it up it locks the joystick? The manual I have shows a different latch below the ring for that, but I've never looked to even see if it was there. There's more than one instance I've found already where the manual was not up to date with the as-built design so maybe the ring is now the lock.
I spent a little over ten years in Dallas. How are things up in Wise County?
