There were two matching ploughing engines doing a demo, not allowed to actually plough, so they pulled a 12 tonne engine (with it's brake on) from one side to another is if it weighed 'nowt - seriously impressive

Best photo I can find of steam traction ploughing using a pair of engines. Each are positioned at opposite sides of field, in line.

A reversing plough is pulled first by one engines underslung winch across the field, then reversed and pulled back by the other after each has moved forward, five furrows in this case. A guy sits on one or other seat to steer the plough and maintain parallel sets of furrows. Imagine the power required especially if the field is sloping.
