There Amish people, the Amish don't have cars or stuff like that, they only have horse/buggy for travel. They do have tractors, but aren't allowed rubber wheels on the power vehicle. So all there tractors have steel wheels, which you can see in the pavement everywhere. You have to be careful in this area of Missouri, near Versailles... theres tons of horse and buggys on the road, always be careful poping up over a hill.
As far as there implements, they can have rubber on them.
I saw one that same day a guy with a older 50+ hp tractor (bid JD) dunno the #, but he had steel wheels, looked like they where 5 ft tall, pulling a dual flex wing brushhog w/tires in the field cutting down something. pretty neat, like the other guy said, it looks like a rough riding thing
I still see them plowing fields with 1 plow or using sickle mowers with only one "horse" too. Lots of ancient machinery still in use.
Alot of them are from farms in Pennslyvania, i dunno much more, i guess there more prominent up there. The children only go to 8th grade, pretty secluded lives. Women wear buns or bon bon type hats, with flower dresses, knee high socks with black shoes, hair pulled back, no hair showing.
The men where dark or black pants, suspenders, straw hats most older gents have beards, and really look like it was some 50 years ago. There really friendly though!
I'm not stereotyping, just informing people that read this.

I think its a really neat way of life, something different, and very very old way of doing things.... definately a harder working, back breaking, simpler way of life.
