looking to get a new tractor for my dad in NH-was all set to get the kioti DK50 hst cab with loader for $28,300 - He just called and found a 2013 1648 DynaQPS Trans with 95 hrs cab for $28500 and also a 2011 1660 cab hydro trans with 500 hrs for $30,000= do not know much about the MF models but he loves them- since he is older with bad legs will the Dyna tranny be a problem- why is the MF better than the kioti and are either of these MF prices seem good to you experts- thanks so much for the advice
