A system for supporting a cutterbar of a crop harvesting header includes a first arm pivotably secured to the header. The first arm includes a first portion configured to support the cutterbar. The first arm includes a second portion including a torsion device having a mass of elastic material connected to an adjustment assembly. The second portion is configured to be pivotably rotatable about an axis by the adjustment assembly to selectably increase or decrease a force appliable to the first portion in order to raise or lower the first portion with respect to the header. A load limiting apparatus limits an amount of torsional force that is applied to the mass of elastic material by pivotable rotation of the second portion about the axis.

System for cutterbar support having torsion device with elastic material and load limiting apparatus

A system for supporting a cutterbar of a crop harvesting header includes an adjustment assembly including a first arm pivotably secured to the header. The first arm includes a first portion configured to support the cutterbar, and a second portion including a torsion device having a mass of elastic material connected to the adjustment assembly. The second portion is configured to be pivotably rotatable about a first axis by the adjustment assembly to selectably increase or decrease a force appliable to the first portion in order to raise or lower the first portion with respect to the header. The system further includes a connecting lever having one end pivotally connected to an interconnecting member and another end coupled to the second arm, wherein the connecting lever has a pivot portion for rotation about a second axis, the second axis is perpendicular to the first axis.

Cutterbar adjustment support for a crop harvesting header

A header for a harvesting machine with a movable cutterbar includes a belt drive mechanism connecting a stationary pulley mounted on the frame of the header and a relatively movable pulley mounted on the movable part of the header. The belt drive mechanism includes two guide pulleys, a belt mounted along said pulleys, and a pivot assembly mounted on the auger shaft. The guide pulleys are mounted on opposite lever arms of the pivot and said belt drive mechanism further includes a tensioning mechanism.

Belt drive for a harvesting header with a movable cutterbar

A header for a harvesting machine having a frame, a cutterbar mounted on the frame operable to cut standing crop, the cutterbar being adjustable relative to the frame in a fore-and-aft direction, and a reel rotatably supported between a pair of reel arms pivotally mounted on the frame and operable to sweep crop material towards and over the cutterbar, a hydraulic cylinder extending between each reel arm and a corresponding side wall of the header frame to effect a generally vertical movement of the reel, comprising an interlock mechanism operably interconnecting the cutterbar and the hydraulic cylinder at each side of the header for adjusting the vertical position of the reel in response to a fore-and-aft movement of the cutterbar to maintain substantially constant the spacing and avoiding interference between the reel and the cutterbar.

Extendable header for harvesting machine

In a header having a movably mounted knife and a guard for shielding the moving and rotating components operating the knife, the guard preferably comprising two interconnected parts of which the first part is mounted on the header so as not to move with the knife and the second part is coupled for movement with the knife. In this way, the area shielded by the guard automatically expands and contracts with movement of the knife.
