With a single pole, most commonly you only have 2 on the pole with a regular yoke and backing power, the 3rd horse is there for forward power.  For a plow this works fine, but if you want 3 to hold a load down a hill you may want shafts or some other alternative set up.


This is the first photo that I have been able to post in ages, Thanks Gabe!
