发明名称 Hay rake assembly
摘要 A hay rake assembly is characterized by the use of two, three, or even more individual hay rakes which are towed behind a single towing vehicle. Each of the rakes is on an individual gooseneck which is under hydraulic control from the towing vehicle so that it will swing out to establish its own swath, independently of the other rakes, on command from the operator of the towing vehicle. This yields great flexibility in the raking of hay and combining of windrows, and the apparatus is also characterized in that each rake may be reversed on its gooseneck so that the hay rake is converted into a tedding machine. Several other angular and elevational adjustment of the rake basket, most of which are hydraulic, also represent part of the invention.
