I think something we are glancing over is that for the extra money of the TC29 there are some serious operational advantages when it comes to the loader and doing that type of work. Someone who is looking at 30hp machines and has some serious FEL work to do would be pretty wise to jump on the TC29 because of the curved & sloped hood and curved loader arms because they do make shorter work of big piles of anything than a "traditional" style tractor. (Granted, a Power Trac unit would be even better for FEL work, but if we limit our choices to any 30hp major/minor brand, the TC29 is among the best choices for FEL work). The ergonomics of the TC29 are outstanding making for efficent use. The standard folding ROPS allows the machine to get into even small barns. The SuperSteer option allows the tractor to work inside barn aisles that would challenge even smaller tractors. SuperSteer is also great for people who do a lot of mowing, especially around landscaping or trees, and can become a dramatic time saver. The TC30's ergonomic layout is based more on the mechanical ease of assembly at a low cost than on the ease of the operator to safely and comfortably operate the machine (this is true of many old style machines as well).
I guess, what it boils down to is that IF you need/want some of the features of the TC29, then you would not even consider the TC30. And if you are simply out to buy the most horsepower for the money, then you would not consider the TC29.
