cub cadet 1320 made in 1991 working condition 400 dollars I have 2 acre yard to mow. Is this a good purchase or is this going to be one nagging problem after another. My other option is to buy a new cheap tractor at sears for a little over a thousand. My yard is flat with no real obstacles. I want the cub cadet but im apprehensive about having a machine that is going to need to be fixed all the time
