Mounting apparatus for swather header

An agricultural system comprising:

• a propulsion unit comprises at least one, generally longitudinally extending, lift arm;
• a generally transversely extending implement comprising a generally transversely extending main frame, said implement having a weight;
• wherein said at least one lift arm is operable to support at least a first portion of said weight of said implement;
• a connection apparatus operable to connect the at least one lift arm to the implement and transmit forces between said implement and said least one lift arm;
• wherein the connection apparatus comprises a suspension mechanism operable to any one or more of, support, isolate, resist, cushion, absorb and dampen static forces and/or dynamic forces during the transmission of said static and/or dynamic forces between the implement and the at least one lift arm of the propulsion unit.

A mounting apparatus comprising:

• an assembly;
• a first connection mechanism operable to connect the assembly to a propulsion unit, the propulsion unit including a lift arm, the first connection mechanism including a boot configured to engage and retain an end region of the lift arm;
• a second connection mechanism operable to connect the assembly to a main header frame of a swather header, the main header frame including a transverse support beam and a vertical strut secured to the transverse support beam, the assembly comprising a lift horn member operable to fixedly connect to the vertical strut with the second connection mechanism;
• a header suspension system including an expandable pressurized gas bag operably interposed between the boot and the lift horn member;
• and
• a pneumatic system configured to control a pressure of gas in the gas bag to, thereby, adjust an extent to which the mounting apparatus is operable to transfer, to the lift arm a force acting upon the main header frame.

An agricultural system comprising:

• a propulsion unit comprises at least one, elongated, generally longitudinally extending, lift arm, said at least one lift arm having a distal end region;
• a generally transversely extending implement comprising a generally transversely extending main frame, said implement having a weight;
• wherein said at least one lift arm is operable to support at least a first portion of said weight of said implement;
• a connection apparatus located proximate the distal end region of the at least one lift arm and operable to connect the at least one lift arm to the implement and transmit forces between said implement and said least one lift arm;
• wherein the connection apparatus comprises a suspension mechanism operable to one or more of support, isolate, resist, cushion, absorb and dampen static and/or dynamic forces during the transmission of said forces between the implement and the at least one lift arm of the propulsion unit;
• and
• a header height control system operable to control a distance between a bottom of the main header frame and a ground level.

An agricultural apparatus comprising:

• a propulsion unit including first and second generally longitudinally extending lift arms, the first and second lift arms being transversely spaced apart and each of the first and second lift arms having an end region;
• a transversely extending header having a weight;
• a first lower connecting apparatus and a second lower connecting apparatus interconnecting the end regions of the first and second lift arms respectively to the header and operable to provide support for at least a portion of said weight of said main header;
• wherein each of the first and second lower connecting apparatuses includes a fluid suspension mechanism operable to at least partly provide suspension between said end regions of said first and second lift arms and said main frame on said propulsion unit.
