Abstract: A crop harvesting machine has a mobile frame which includes a main frame portion supporting a harvesting header along a forward side thereof and a mobile auxiliary frame portion supporting the main frame portion in overlying relation and pivotal in relation thereto about a vertical axis. When the machine is in its field operating orientation, the auxiliary frame portion aligns the main frame portion and header in transverse relationship to the forward direction of machine movement. The machine further has an elongated draft member pivotally mounted about a vertical axis at a central location along the main frame portion and extending longitudinally forward over the header to a forward end adapted for securement to a towing tractor. Conversion of the machine to a road transporting orientation involves: first, actuation of controls for elevating the machine with respect to the field and; then, in coordinated fashion, pivoting the auxiliary frame portion and draft member relative to the main frame portion so as to realign the main frame portion and header generally parallel to the draft member and the forward direction and transverse to the auxiliary frame portion.

Abstract translation: 作物收割机具有可移动框架，该移动框架包括：主框架部分，其沿着其前侧支撑收割头部;以及移动辅助框架部分，其以上下关系支撑主框架部分，并围绕垂直轴线枢转。 当机器处于其现场操作方向时，辅助框架部分与机器运动的正向横向地对准主框架部分和头部。 该机器还具有一个细长的牵伸部件，其绕垂直轴线枢转地安装在沿着主机架部分的中心位置处，并且在该集管上纵向向前延伸到适于固定到拖拉机的前端。 将机器转换为道路运输方向包括：首先，致动用于相对于该场升高机器的控制器; 然后，以协调的方式，使辅助框架部分和牵伸构件相对于主框架部分枢转，以使主框架部分和集管大致平行于牵伸部件和前进方向并横向于辅助框架部分重新对准。

Abstract: A self-propelled agricultural harvesting machine has a link-type suspension mounting a crop cutting header on a tractor. The suspension comprises two spaced suspension assemblies each having upper and lower links and suspension springs supporting the header in cooperation with ground engaging skid shoes and moving the header on variations in ground level so that cut crops are discharged against the windrow- or swath-forming means underneath the tractor at substantially the same location and having deflection means for smoothly guiding end discharged crops from the long conditioning rolls to the narrower windrow and swath forming means.
