Had a chance to see a basic 55 HP model. OMG - what is Bobcat thinking. Only one step on right side facing the tractor. Plastic fuel tank is under the step and right behind the front tire. Zero protection - just 6" away. Rear has no adjustable distance links on lift arms, just turnbuckles. I think it is a cat II set up. Now not everything is bad on all models there is a lever out back to raise and lower the 3pt. This makes it super easy to hitch up - assuming you can get it perfectly lined up. I wonder if that lever will fit the older models. The tractors also appear to be shorter with the fuel tank moved from center behind the engine. I also learned there is a re-gen stop button so if you in woods or grass you can prevent it from getting the exhaust hot.
I'll try and get pictures next time I am there.
