Weights of tractors
Looking at the two posts above, it appears that a WW2 vintage D7 (tractor only) could have been transported and possibly dropped from a Hercules. Most construction machinery gets heavier over time for the same model name as part of the competition to say "my toy is better than yours". Current production D7 weighs between 56 and 60 thousand pounds (operating) or 46 to 50 for shipping. Horsepower is now quoted as 240. Quite a change from the earlier versions.
