This site has a quote from the memoirs of one Sgt. Randy Hanes, of the 300th Combat Engineers. Sgt. Hanes describe the process of removing a wrecked German Panzer from a road thusly:

Here is what we did. All of our 2½ ton trucks had a powerful winch on the front. We would back the truck across the road, lash the trailer-hitch to the nearest tree with 1" hemp hawsers with about six loops around the tree and then hitch it. We would run the steel cable from the winch, across the road, and above the stricken tank, lash it to a pulley as high as we could on the nearest tree. The higher the pulley the greater the lift. We would run the cable through the pulley, take it over the tank, and down as low as we could to the track or chassis. The tanks, being so heavy, made it impossible to drag so we had to lift it on its side, get it high enough to topple on its own. Sometimes, depending on the slope of the shoulder, they would roll completely over with "tracks to the sky." The most hazardous part was that if a cable snapped it could kill several people standing too close.

So since the Panzers were too heavy to drag, the combat engineers would instead rig up pulley system using the electric winch on their M35 trucks, and just flip the Panzer on it's side!
