I have the great good fortune to have grown up in South Central PA, Lancaster County to be specific, home to the oldest and largest contingent of Amish and Old Order Mennonite in the US. To this day it is not unusal for me to see teams of five or six horses abreast at work ploughing the fields in Spring or again in Autumn harvesting. The largest team I remember was a team of eight, in two rows of four abreast. I don't recall ever seeing a driver need to go to the front of the team to direct them. When I was a young lad my paternal grandfather grew tobacco. The tobbaco planter was horse drawn by a team of two belonging to a neighboring Amishman. I often held a pail of cool water up for each horse to drink while the water tank on the planter was refilled. When my father was a boy my grandfather farmed with horses.
