Re: John deere 1070 72" Mower Deck
Here's the 72" that goes onto my 1070. There are several considerations for brackets, depending on what tires you have. I have the large ag tread size. That requires the longer drop bracket that hangs off the front, and the larger "pork chops" that bolt onto the main frame. This mower uses a 3:1 reduction gearbox for use with the mid-pto. There are also kits for using a back feed prop shaft to a 1:1 gearbox off the rear pto if that's the way you want to go.
Yes, the covers have been removed to show the underneath. There are also two hinge brackets that get added to the 3 point arms to pull up the mower via some long pull rods. I have all the stuff for a 1070 mid-pto drive (including the deck) that I don't use anymore. I'm in central Michigan.
