Would like your help with an upcoming purchase.  Live on 39 acres, 30 pasture and 10 acres wooded.  Annually put in a 2 acre food plot that will require a 2 bottom plow every 3 or 4 years, and tilling every year and planting with a drill.  Already own the plow and 6' rotary cutter to mow 30 acres.  Would like a rear attachment snowblower when needed.  No hills or steep areas to contend with on the land.  I am trying to decide between a JD 3720 with loader or a JD 4320 with loader.  Fuel efficiency should be considered of course.  My food plots take up 3 days or so a year.  The main job other than small tasks for the loader is the pasture mowing.  So which tractor would make more sense for my operation.
