The problem is that neither the M1 nor the M60 or indeed neither any tank, has sufficient ground pressure to drive a [bulldozer] blade into even marginally hard ground. They are not bulldozers, they are tanks, whether you are talking about the M1 or the M60's. So if you are going to dig in a tank, you need to have some kind of equipment.
