No didnt have to " go around " The front unit now loaded Pulled the rear unit. They often filled at the same time. Finishing each helping each other.

nothing will move dirt more efficiently ( in the right ground conditions ) than a push poll scrapers.

Terex maybe had the rear engine units before Cat did

27.00 BS, the loading process did not waste time swapping ends to load,both machines worked together as traction transfers with weight to the loaded machine which is then pulling the loading machine till it is filled. Then they separate to tram to the dump area.
