Just down the road from the machine shed of Pennville, Ind., strip-tiller Shane Houck, a tan boulder stands halfway between the edge of the cornfield and the county blacktop. Cut into the top of the rock is the inscription, “Houck Homestead Farm 1838.”

No-tillers descended upon central Iowa at the end of August to see the latest equipment and production tools during the annual Farm Progress Show. Here’s just a glimpse at some of the new products or technologies seen and talked about during the 3-day event.
