in Lancaster County belong to the Groffdale Conference, while harder sounding carriages are either Reidenbachers(black with windows) or Stauffers(black without windows, just a frontshield). Young people during "Rumspringen" put lining on their carriages´ wheels, which is partly allowed among Reidenbachers. In former times Groffdalers drove a folding top buggy during courting time and as young couples, but that changed to the closed-up wagon type their parents use too, just with fancy lining on wheels etc.. In the late 1990s one could still see some folding-top buggies among them. Quoted Reasonings for the change were that getting cold hands could be prevented better and protection anyhow by the box-like type during heavy weather conditions. Well, this was for decades accepted, so mainly a longing for more comfortability was prevailing, which changing times also allowed for the youth later. They are mainly rural people, who work small farms. Groffdalers rather move than are fixed to landscape like Amish of Lancaster County and have a tendency to still prefer agriculture for everything else. The Amish have instead, staying in Lancaster County mostly, sought for other occupations. Initially concentrated in eastern Lancaster County, Pennsylvania, they resided in eight other states as of 2002. Church members use modern self-propelled farm machinery and lawn mowers that have been refitted with steel wheels. Starting in the 1970s, some farmers used rubber belts and blocks to give wheels more traction, provide a smoother ride and reduce damage to public roads. This practice caused considerable debate within the community, which was resolved in 1999 with a compromise that allows limited use of rubber in the structure of steel wheels. Hard rubber or pneumatic tires are allowed on bicycles and machinery not requiring a driver, such as walk-behind equipment and wagons. Use of steel wheels ensures tractors are not used as a substitute for automobiles to run errands or to make more extensive trips than are convenient with horse-drawn carriages. The steel wheel rule prevents large agricultural operations, reinforcing an emphasis on small farms that provide manual labor for all of the family members.
