Abstract
SUPPORT LINKAGE FOR MOUNTING A HEADER ON A SUPPORT FRAME
ABSTRACT OF THE DISCLOSURE
The header support linkage of a swather header on a support frame of a swather comprises a substantially vertical beams an upper cross arm formed from a channel and a lower support cradle arm projecting outwardly from the bottom of the beam. A lower link projects from the frame forwardly to engage the lower part of the beam and is formed by an expandable cylinder to lift the header. An upper link extends from an upper part of the frame along the inside of the channel forming the upper arm. A cylinder extends from a lower part of the frame to a lever pivotally connected to the upper link providing a lost motion connection. An adjustable stop is provided between the upper link and the inside of the upper arm. A float spring is connected between an outer end of the upper arm and a vertically adjustable slide provided on the frame. The linkage provides adjustment for different header weights and an effective lifting action of the header from a preset cut height to a raised position both by a lifting action and by a floating action.
