I have a 1440,nice little combine.You should be happy with it in your situation.The 1440 shares threshing parts with a 1460 so you have enough capacity inside.The 1440 uses a lghter trans.,can be a problem,and lighter final drives.I think the 1440 uses the same final drives as the old 815 for what that is worth.Depending on hours and previous use,the transition cone can wear a hole in the bottom left corner,but that is common with all axial flows.I use a 6 row head on mine,and a 17.5' bean head,but thinking about going to a 20' head next year.Most of my corn acres are in seed corn,so I only have about 160 ac. of corn,but about 350-380 ac. of beans.Good luck.
