First pic is a 1939 D4 with 5 roller undercarriage. Pony runs very well. Diesel starts and runs great also.  Equipped with really uncommon street pads. Has brand new clutch throw out collar installed. All fluids changed in entire machine.  I have a trackson 10ft blade that fits this machine as well. 
Second pic is a 1949 D4. Appears to be stuck. I purchased this for parts and the Hydraulics for the blade. One track is off its sprockets. But it is a complete machine. 
Will need a heavy trailer to haul these as they weight around 12-13000 lbs each. Let’s chat if your interested 
asking $3500 pair

Do you still have these? I'm located to the west of you in Kirklin IN. Thanks!

I don’t have the dozers themselves but do have a few odds left. 10ft blade injectors fuel pump generator starter clutch
