Abstract
A header is removably attached to lift arms of an agricultural harvester by mounting pins received in upwardly facing recesses on the ends of lift arms. A bar is moved into locking position by a lever arm mounted on the lift arms to hold the header mounting pins in place. A hook shaped latching device is pivotally mounted on the lift arm adjacent the lever arm for capturing it in place against the lift arm.
Claims12
A lift arm apparatus comprising:
- a lift arm having a U-shaped recess at its free end for receiving a mounting pin of a component;
- a bar movable on said lift arm between an open position permitting installation and removal of the component mounting pin and a locked position holding the component mounting pin in said U-shaped recess;
- a lever arm pivotally mounted on said lift arm and having a first end connected to said bar and a second end pivotable about a vertical axis between an unlocked position permitting installation and removal of the component mounting pin wherein the second end is away from said lift arm and a locked position against said lift arm;
- and,
- a hook shaped latching device pivotable about a horizontal axis adjacent said lift arm and above the plane of movement of said lever arm, said latching device having the hook facing said lift arm and pivotable between an unlatched upper position permitting movement of said lever arm away from said lift arm and a latched lower position in which the hook shaped latching device captures said lift arm to hold it adjacent said lift arm.

An agricultural harvester comprising:
- a frame;
- ground drive wheels connected to said frame for ground movement;
- a header removably attached to said frame for harvesting agricultural crops, said header having at least one mounting pin;
- at least one lift arm having a U-shaped lift arm connected to said frame for pivoting movement and having a U-shaped recess at its free end for receiving said mounting pin;
- an actuator for raising and lowering the free end of said lift arm;
- a bar movable on said lift arm between an open position permitting installation and removal of said header mounting pins and a locked position holding the header mounting pin in said U-shaped recess;
- a lever arm pivotally mounted on said lift arm and having a first end connected to said bar and a second end pivotable about a vertical axis between an unlocked position permitting installation and removal of the component mounting pin wherein the second end is away from said lift arm and a locked position against said lift arm;
- and,
- a hooked shaped latching device pivotable about a horizontal axis adjacent said lift arm and above the plane of movement of said lever arm, said latching device having the hook facing said lift arm and pivotable between an unlatched upper position permitting movement of said lever arm away from said lift arm and a latched lower position in which the hook shaped latching device captures said lever arm to hold it adjacent said lift arm.
