R Walter, My TC40D with the loader and loaded rear R4's ,with 6' box blade I figure to weigh about 5000#. I'm not sure of the dimensions with the loader and box blade but you could easily figure at least 16' long. I'm sure there are some others on this board that could give you the exact dimensions and weights. I would reccommend going to the New Holland web site for all the specs. I went with the TC40D rather than the smaller frame NH so I could get the added loader and 3pt hitch lift capacity. Not sure of comparable JD or Kubota models as I haven't been comparing since I bought my NH. I have been very happy with my tractor and have not had a single problem with it in the 2 years I've had it. I don't have a lot of hours on it (about 130) since I don't do any mowing, just loader and box blading work on my 15 acres. Due to a change in jobs I may be looking to sell this tractor this summer. It is a 2003.
