    Abstract: 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.

  • Patent number: 8544250
    Abstract: A draper platform (100) has a center endless belt conveyor (118) that is supported on and between first and second adjacent support arms (246A, 246B). The center endless belt conveyor (118) is releasable from a first support arm (246A) of the two adjacent support arms to pivot downward away from the first support arm of the two adjacent support arms a distance sufficient to slidably remove an endless conveyor belt (134) from the center endless belt conveyor in a direction parallel to the axes of rotation of the rolls (300, 302) that support the endless conveyor belt.

  • Publication number: 20130247529
    Abstract: A harvesting machine includes a harvesting header with a header frame, a cutterbar assembly attached to the header frame along the length thereof and configured to cut a crop, and a draper assembly positioned behind the cutterbar assembly and operable to receive severed crop material from the cutterbar assembly. The draper assembly includes a center draper that delivers crop material to a feeder house of the harvesting machine and oppositely spaced side drapers that deliver crop material to the center draper. The harvesting header is operable to flex and thereby follow an uneven terrain.
