Henro,
I've had a similar crazy idea, but it might be  slightly crazier.  I've started to clear some of the woods and expand my lawn while leaving many of the trees.  My TC33 is a little big for these tight maneuvers, so I realized what I need is a ZTR, but not any ZTR; the Kubota ZD21 should handle my rough terrain, and with it's commercial deck will easily eat any weeds...or saplings.  /forums/images/graemlins/shocked.gif  Now what do I do with my TC33, well naturally I'll need to trade it in on a TC40.  /forums/images/graemlins/grin.gif  I've started mentioning my idea to the CFO, but it will probably take a couple of years to bring her over to the dark side.   /forums/images/graemlins/wink.gif 
Unfortunately, I don't have any kids, so I have to take the entire blame for my ideas.    /forums/images/graemlins/blush.gif
