Since we havent used our combine for many years, I would need to pay someone to do the combining too. Alfalfa/grass hay is going for around $3/bale now, so I would need to make $3000 off the field to pay for the hay I need. Risk in combining is messing up the alfalfa if the oats get flattened or the windrows get rained on. YT Home | Forums.
Erasers. In 1770, the first version of the rubber eraser was sold by an English optician and engineer named Edward Nairne. Edward got his invention by accident âhe meant to pick up bread crumbs to erase some pencil markings, as was common at the time, but his hands landed on a nearby piece of rubber.
Ancient people were a pretty clever bunch. They invented many things to make their life more comfortable and fun, things we still use today like fire, the wheel, the sailboat, paper, silk, kites, tea, umbrellas, ice cream and many more! advertisement. advertisement.
