a quick and easy tutorial which can help you farm very quick!
the tutorial was based around an idea I had about a year ago, but pistons weren't around so in 1.7.3 when they came out i was experimenting, not it wasn't until now that I had found a solution and 100% efficient way to farm so I made a quick tutorial, the best part is is that it doesn't unplow the land so its great!!!!!!!!!!!!!!
