Concerning the use of technologies, the Nebraska Amish are about as restrictive as the Swartzentruber Amish, see table below. Like other Old Order Amish, the Nebraska Amish do not use motorized equipment or indoor plumbing. Other differences include the fact that they do not place screens on their doors or windows, men only wear white shirts, curtains are not used in homes, buggy tops must be white, men's hair must be shoulder length, no lawn mowers are allowed and houses must not have projecting roofs.
