i am hopeing that some of you more experienced guys can help me understand this. The machines that I am lookng at have anywhere 3.5 up to 5.1 ground . The rep at the case dealership said that his low GP D6 dozer has 5.5. I need a machine that can handle heavy loads up and down hilly terrain. However I am a small company and frankly can not afford multiple Track loaders. The case is a beast of machine as far a specs go but being that I working a high end residential market I can not afford to have to replace every piece of turf I Drive across. So I gues my question is will there be a noticable difference in track depths (over sensitive ground) between machines of equal weights that have that a big difference in ground pressure difference (3.5-5.1). Thanks again for your time and knowledge.
