This photo shows a team of plow horses hooked to a sled loaded with manure that was cleaned out of the horse barn.

The barn was cleaned using a wheelbarrow and manpower.  First, the manure was shoveled by hand out of the gutters and into the wheelbarrow and then hauled out to the sled. In the winter, the manure was either piled outside until it could be hauled away in the spring, or hauled to the fields on a sled and off-loaded by hand.
