My uncle had one of those on his 8N and we used it many times; one of
which was to pour the floor in a 46 by 80 ft. pole barn. The roller
that drove the mixer was ran by the pto but had its own bearings and
housing and actually bolted to the same place as the belt pulley for the
8N mounted so actually their was no strain on the pto bearing.
