Trouble is its a AC which in the Construction has been a dead issue for a number of years .
Will the plow fit a D8 or Komatsua or Even a Dresser TD 25 or 30
Could it be re engined with a Cummins or Detroit ?
Does it have the Diesel Torque converter?
Have seen a number of smaller ACs re-engined to Detroit's.
Hope this helps , if it was closer would think about it and reengine it with something more common .
