Multi-section header with flexible crop cutting knife

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. ... Macdon Industries Ltd

Crop machine with an electronically controlled hydraulic cylinder flotation system

A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a pprr valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. ... Macdon Industries Ltd

Crop machine with an electronically controlled hydraulic cylinder flotation system

A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a pprr valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. ... Macdon Industries Ltd

Header with flexible crop cutting knife mounted on flex blades

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. ... Macdon Industries Ltd

Header with flexible crop cutting knife cooperating with a fixed draper engagement member

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. ... Macdon Industries Ltd

Sickle cutter system

In a sickle cutting system, it has been found that a significant reduction in average stubble length, which is calculated based on the distance crop is pushed forwardly without cutting occurring, can be obtained by a combination of the features where the length of the cutting edge of each knife blade from a transverse rearmost cutting line at which a cutting action occurs is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.2 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.. . ... Macdon Industries Ltd

Crop machine with an electronically controlled hydraulic cylinder flotation system

In a crop harvesting machine there is provided a pair of hydraulic float cylinders for a header relative to a vehicle, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a pprr valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. ... Macdon Industries Ltd

Dual sickle knife drive

A sickle cutting system is mounted on a header for forward travel over ground having a standing crop thereon and includes a cutter bar with a plurality of knife guards and two opposed sickle bars driven in opposite phase with a drive system for driving the sickle bar through repeated cycles of reciprocating movement from start-up of the system through to a shut-down. The drive system includes a control device responsive to the sensor signals from both of the first and second drive systems for advancing or retarding one of the first and second drive systems so that a number of sensor signals obtained from the first drive system is continually maintained so as to be substantially equal to a number of sensor signals obtained from the second drive system to maintain the sickle bars in opposite phase.. ... Macdon Industries Ltd

Halting the sickle bar of a sickle cutting apparatus at a predetermined position

A sickle cutting system is mounted on a header for forward travel over ground having a standing crop thereon and includes a cutter bar with a plurality of knife guards and at least one sickle bar with a drive system for driving the sickle bar through repeated cycles of reciprocating movement from start-up of the system through to a shut-down. The drive system includes an arrangement to halt the sickle bar on shut-down at a predetermined position of the knife blades relative to the knife guards and preferably the position where the blades lie intermediate two knife guards. ... Macdon Industries Ltd

Crop harvesting machine with a header separable from a tractor

In a swather a support arm is attached to the header to carry the heavy hydraulic hoses which are connected to the tractor for supplying the drive fluid to the hydraulic system of the header. The support arm is articulated so as to accommodate the up-and-down and twisting movement of the header relative to the tractor during harvesting action and this supported to prevent collapse when the hoses are disconnected from the tractor manifold. ... Macdon Industries Ltd

Swather tractor swath with a compressor attachment

A swather includes a swath compression panel with a downwardly and rearwardly inclined undersurface for applying a downward compression force on the swath between the front and rear wheels. A mounting assembly includes an actuator operable in response to a speed and/or direction of travel of the tractor for raising the panel to a retracted position under the tractor. ... Macdon Industries Ltd

Sickle cutter system operable with pointed guards and stub guards

A sickle cutting apparatus includes double finger knife guards where the ledger surface of each guard finger has a width at an imaginary line joining the apexes between the rear edges of the blades which is greater than a spacing at the imaginary line between the first side edge of the ledger surface of each guard finger and the second side edge of the ledger surface of each next adjacent guard finger. The first and second side edges of the ledger surfaces of each of the guard fingers extend to a position behind the imaginary line so as to be free from any trash bar connecting each to the next in front of said imaginary line. ...
