At our cross country invitational a couple weekends ago there was this cool hay rake parked in the field. I love the colors, assuming it has been used just a few times as there is little wear on the new paint.
Hay rakes will take 20-25 foot sections of cut hay or straw and channel it into windrows for bailing. Windrows are just piles of hay in rows. After the hay is dried bailers will create smaller rectangular bails or the larger circular bails. I worked as a hired hand on a farm growing up and I had to toss bailed hay into the back of a moving pickup and then pile it in a caboose. Being allergic to hay and not a professional weight lifter, this was one of the worst jobs I ever had!
