Support apparatus for harvesting equipment
Abstract
Abstract A SUPPORT APPARATUS FOR PUSH-TYPE HARVESTING EQUIPMENT THAT IS SPRING COUNTERBALANCED SO AS TO "FLOAT" IN CONTACT WITH THE FIELD SURFACES OR IN CLOSE PROXIMITY THERETO. THE HARVESTING EQUIPMENT, IN THE FORM OF A SICKLE BAR AND REEL, IS SUPPORTED FORWARDLY OF A TRACTOR VEHICLE FRAME BY TWO TRANSVERSE HEADER BARS WHICH EXTEND LONGITUDINALLY UNDER A SUBSTANTIAL PART OF THE VEHICLE FRAME. THE FORWARD END OF EACH HEADER BAR IS FIXED TO THE HARVESTER APPARATUS. THE REAR ENDS OF THE HEADER BARS ARE MOVABLY CONNECTED TO THE VEHICLE FRAME ABOUT A SWIVEL CONNECTION THAT PERMITS ONE END OF THE HEADER TO MOVE VERTICALLY RELATIVE TO THE OTHER. A CENTER STABILIZING CONNECTION BETWEEN THE HARVESTING APPARATUS AND VEHICLE FRAME PREVENTS LATERAL MOVEMENT OF THE HARVESTING APPARATUS. ADJUSTABLE SPRING COUNTERBALANCE SUPPORTS AND HYDRAULICALLY OPERATED LIFTING DEVICES ARE PROVIDED FOR PROPER ELEVATIONAL CONTROL OF THE HARVESTER EQUIPMENT.
