When I first got my CK25, the ground was wet and I made a mess of a part of my lawn (R4's). Now I keep it out of the tender parts of my yard when its wet. I bought it for ground engaging work in the woods and on some steep slopes anyway (no mowing). I too seriously considered the T273 for the woods. But, opted for the heavier machine. I've started taking the CK25 into the woods. In about an hour or so I had cleared about half an acred of multifloral rose, sassifras, small cheeries, viburnum, and grape vines. What it didn't dig up it just ran over! Man what a work saver! Though I do have some spots where the smaller machine would fit better. The CK25 is way over kill, except for some very specific tasks, for my property. But for about the same money, I have a lot more tractor. Anyway, I know you can't wait to put yours to work too. Keep us posted.
