摘要： A convenient user-friendly method to sharpen the rotary blade of a rotary cutter assembly without having to turn the rotary cutter assembly upside down. To this end, a rotary cutter assembly is provided with a special access door which is preferably securely fastened and/or locked during cutting and use of the rotary cutter assembly. When it is desired to sharpen the rotary blade, the door is unfastened and opened to permit access to the rotary blade. The rotary blade can then be clamped or otherwise secured and subsequently sharpened with a grinding wheel or other sharpening tool.

摘要： A draper header includes two side drapers each running from an outer end guide roller at a first end of the header to an inner end guide roller adjacent the discharge location of the header and a central feed draper located at the discharge location and including a front guide roller just behind the cutter bar and running to a rear guide roller in front of the feeder house of the combine harvester. An auger is located between the discharge rollers with a front edge of the flight forward of the rear end of the discharge rollers to feed the material inwardly and underneath the auger to the inlet of the feeder house. The feed draper carries cleats which are angled to the rollers in two sections converging to a central leading apex to reduce forces on the cleat as they pass over the front guide roller which is of reduced diameter to fit within a small space adjacent the cutter bar. The connection at the ends of the draper canvas is also angled to the rollers so as to be parallel to the cleats and includes separate connectors having a convex shape.

摘要： A lawnmower deck includes a deck sub-assembly and a stiffener. The deck sub-assembly has a top surface, a skirt extending outwardly and downwardly from the top surface and encircling the top surface and a first stiffness. The skirt defines a cutting chamber underneath the top surface and a plurality of wheel mounts. The stiffener is connected to at least one of the top surface and the skirt. The stiffener and the deck sub-assembly together have a combined stiffness that is at least approximately 20% greater than the first stiffness.

摘要： A crop harvesting header for mounting on a propulsion vehicle such as a swather tractor or combine harvester includes a main frame structure supporting a crop receiving table with a cutter bar across a front of the table and side drapers on the table for moving the cut crop toward a discharge location of the header. The frame is divided into a central frame portion and two separate wing frame portions each arranged for pivotal movement relative to the central portion about a pivot axis extending in a plane parallel to the forward direction and intersecting the cutter bar so that, as the wing frame portions pivot, the cutter bar flexes in the area adjacent the respective pivot axis over a small angle of the order of 4 degrees to maintain the cutter bar following the ground. The central frame portion is mounted on two spring arms for upward and twisting floating movement such that the total downward force on the ground, from that part of the weight of all of the portions of the header which is unsupported, can be varied by moving the support to change the total pressure of the header on the ground. The wing frame portions are connected to the central frame portion by interconnecting linkages which transfer weight from the wing frame portions to the springs of the central portion each including a respective balance beam arranged to balance the lifting force from the spring with the downward forces from the center portion and wing frame portion such that the downward force on a skid plate of each portion on the ground varies automatically as the total downward force is varied. A bottom stop is arranged with a balance system which holds the cutter bar straight when the header is raised.

摘要： A harvesting header for a self-propelled harvesting machine comprising a center portion and two side portions. The center portion and both side portions are provided with forwardly extending crop processing arrangements. A transversely extending auger is located behind the crop processing arrangements. The crop processing arrangements can be moved between an operating position and a transport position by pivoting them about a transversely extending horizontal pivot axis. In this transport position the center of gravity of the harvesting header is moved rearwardly towards the harvesting machine. The side crop processing arrangements can be pivoted about forwardly extending pivot axes to reduce the width of the harvesting header in its transport position.

摘要： A cutting chamber for a mower deck blade is comprised of first and second adjoining skirt members of differing lengths to provide for a lifting air stream at the front of the chamber and a discharging air stream at the rear of the chamber. As a result, cut material can be recut in a mulching action and then easily discharged to the rear of the deck.

摘要： An attachment for the mower deck of a mower for striping the cut grass, and the method of use thereof. The attachment is a brush adjustably affixed to the rear of the mower deck, behind the cutting blades, and extending perpendicularly across the path of the mower. The brush is adjusted up and down to vary the amount of interference with the cut grass. As the brush is pulled across the lawn behind the cutting blades, it contacts the cut grass blades and bends them over in the direction of travel.
