Again, not sure what the "heaviest 55 hp tractor" has to do with anything. One can always add weight, be it loader, wheel weights, backhoe, winch, cab, etc. infinitum.
One could put 55 hp engine in a tank, and it may move it about, and only mention it to stretch the point. What good would it be?
Not meaning to de-mean the heavy tractors with 55 hp power plants, but don't see where this end of a discussion has useful meaning. Good balance of the weight to hp is important, depending on the conditions (hillsides, in the woods, etc. is one of those conditions).
Good flexibility seems to be to have the horses and not the weight, as that end of the spectrum brings up possibilities that have not existed in the past.
What am I missing here? /forums/images/graemlins/confused.gif
