摘要: A harvester reel for an agricultural harvester header includes a central rotatable shaft; a plurality of reel tine bars and a cam assembly for guiding rotation of the plurality of reel tine bars. The reel tine bars extend widthwise across the reel and are connected to the central rotatable shaft for rotation therewith. Each of the plurality of reel tine bars include a tine. The cam assembly includes a cam and a diverter adjacent the cam. The diverter is movable between a disengaged position, in which the cam does not guide rotation of the tine bars, and an engaged position, in which the cam does guide rotation of the tine bars. The diverter is biased toward the engaged position.

摘要: A mowing sickle drive system comprises a knife bar supported by a frame and drive apparatus operable to drive the knife bar in a reciprocating linear motion at a variable drive frequency. A spring is coupled to the knife bar for applying a restoring force to the knife bar toward a neutral position when in motion. The spring has a variable modulus of elasticity that is controlled dependent upon the drive frequency.

摘要: In a sickle cutting system including a plurality of guard fingers at spaced positions across a cutter bar across which a reciprocating sickle knife passes, each guard finger has a forwardly projecting tip portion in front of a ledger surface and a rearwardly projecting tang portion connected to a rear end of the tip portion and extending therefrom over the ledger surface to a rear edge of the tang portion located over the blade. The lower surface of the tang portion includes a first portion adjacent the tip portion which is generally parallel to the ledger surface and a second portion adjacent the rear edge which is inclined at an angle away from the ledger surface. The width of the tang portion across the rear of the tang portion is equal to or greater than 1.5 inches.

摘要: 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. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

摘要: The stripper is a flange member supported on the upright backboard of a crop harvesting header to span a gap between the backboard and a cross auger. The cross auger is supported above a draper on the header to assist in guiding the cut crop being conveyed by the draper to a central rear discharge of the header. The stripper flange member extends forwardly towards the cross auger at an upward inclination so as to be oriented at an angle of greater than 90 relative to a portion of the backboard of the header immediately below the stripper flange member. The stripper flange member is thus better oriented to guide cut crop which rises up the backboard to be deflected forwardly into the cross auger, instead of acting as a stop to accumulate cut crop thereon when the flange member is oriented perpendicularly to the backboard.

摘要: A draper seal for a crop harvesting header is provided. The header includes a forwardly disposed cutter bar assembly and a rearwardly disposed draper deck assembly. The draper seal includes a flexible strip that runs parallel to the cutter bar assembly and perpendicular to the direction of travel. A bracket secures the forward edge of the flexible strip to an upper surface of the cutter bar assembly, which bracket also biases a rearward edge of the flexible strip into engagement with an upper surface of the draper deck assembly, thereby creating a seal between the cutter bar assembly and the draper deck assembly.

摘要: A sickle cutting apparatus includes a plurality of triple finger knife guards which are arranged side by side along the cutter bar to cooperate with a reciprocating sickle bar carrying a row of double blade knife sections and a set of hold-down members carrying hold-down fingers. The hold-down members are arranged alternately as a single finger and double finger with each hold-down member being connected to the cutter bar in association with a respective triple guard. In this way the hold-down fingers are arranged at alternate guard fingers leaving the intervening guard fingers open. The system includes both pointed guards with no tang and stub guard so that the user can select either to be used with the hold-downs. The hold down fingers are all individually adjustable so that the double hold-down have two adjustment screws which can be individually operated causing flexing of the bridge between the double fingers.
