Abstract
Abstract An apparatus for forming rolls of hay from a swath lying in a field. A wheeled frame has a forward frame portion and a main frame pivoted at the forward end thereof to the rear end of the forward frame portion. A vehicle lifting means is mounted on the forward frame portion and is coupled to the main frame for pivoting the main frame around the pivotal mounting on the forward frame portion. A downwardly open hay collecting chamber is provided on said main frame and a hay raking and lifting means is mounted on the rear of the main frame for raking the hay in the swath forwardly of the main frame and at the same time lifting it upwardly into said hay collecting chamber. Drive means on the main frame is coupled to the hay raking and lifting means for driving the hay raking and lifting means. As the apparatus is moved forwardly over a swath of cut hay, the hay is raked and lifted into the hay collecting chamber and rolled up snowball fashion, and when the desired size of roll is achieved, the apparatus is stopped and the vehicle lifting means actuated to raise the rear end of the main frame above the level of the top of the roll of hay, and the apparatus can then be moved forward over the roll of hay.
