Someone had managed to gather together about 60 farm implements and wagons and has decided to put them on display. The vast majority of the farm implements are very old horse drawn machines. The collection includes plows, cultivators, harrows, discs, mowers, corn planters, farm wagons, potato diggers and planters, a hay loader, a manure spreader and two road graders. The display is immediately north of the highway and appears to be accessible 24/7/365, at no charge.
When plowing using a conventional plow, the operator cannot return in the same furrow he just made, as the plow will then turn the soil in the wrong direction. What does he do? He returns in another furrow which, in a wide field, can be some distance away. This is why the 2 way plow can be such a time saver - simply turn around and return on the same furrow one just came up.
How does this work, you ask? Simply by attaching a second plow share, a mirror image of the first one, in the same frame. Use the first share on the initial trip up the field and the second share on the return trip. We have yet to discover who it was that first invented the 2 way plow and when they accomplished the task. We do know that they were in use by 1917 - probably a lot earlier.
