I am thinking of purchasing an Exmark for mowing 1 acre of grass at my home. I looked at a used 32" Metro today and wasn't sure if there is a way to adjust the cutting height, it looked fixed at about 3" and the owner had just used it as it was set. Is there a way to adjust height on the fixed deck mowers, or would I need a floating deck to get adjustability. Also the mower I looked at had an 8.5hp Briggs and Stratton engine, is this a dicontinued model? Was it ever available with 8.5hp or is this likely to be a replacement engine?
