  • Patent number: 4214428
    Abstract: During a single pass, cut hay or grain in a twenty foot wide swath is cleared by the action of a pair of multiwheel divergent rakes coupled to the front end of a wide wheel farm tractor. The two rakes produce a single five foot wide windrow of hay or grain over which the tractor can pass, and a conventional round baler towed by the tractor produces round bales which are deposited in the field behind the machine. The necessity for separate raking and baling passes utilizing separate tractors is eliminated. The front-mounted rakes can be hoisted and folded to facilitate roadway transport.
