The Drill motors actually come out quite easy, just a couple of set screws that Protrude into the holes in them and some gental taps and they should come right out all the way through the 2x4.
As for tourque, it has approximatley 31.5 theortical ft/lbs of tourque at 40 A per side in low gear, giving it pushing theoretical pushing force of 378 pounds at 40 A not taking any friction etc. into account. That is about 1100 pounds of push at stall in low gear, Which is impossible to reach since the battery can't provide that kind of current. Combine that with VERY grippy tracks and we should be somewhat of a bulldsozer out there, with good intentions of course.
