What a coincidence! While browsing either this or some other forum a couple of days ago I came across a posting where someone asked about articulated tractors like the PT, and somone else responded that one of the problems with articulated tractors is that if you get too close to something like a wall (in your case, a tree) you could get stuck making the machines not that ideal for those who often work close to obstacles (like walls). I'm thinking those folks in the landscaping and grounds maintenance professions.
Thanks for proving it! /forums/images/graemlins/wink.gif
What you really need is another PT, a bigger one, with forks, that can lift your 422 up and away!
