Method and means for adjusting hay conditioner rolls

摘要

Disclosed is a hay conditioner of basically typical construction in which the improvement lies in adjustable stop means for use in setting and varying the clearance between the upper and lower conditioning rolls. There is provided at each side of the machine a means including a lever arm disposed below a support for the upper roll and pivoted at one end on the adjacent side of the machine frame, the other end being connected to a screw-threaded adjustment link effective to elevate the lever for engagement with the upper roll support and thus to selectively limit downward movement of the upper roll under action of the usual biasing means. Thus, the upper roll is free to move upwardly in response to crops passing between the rolls, but its downward movement is limited to the stopped position selected by the adjustment link. The link extends upwardly to a free end that is easily accessible to receive a force-applying tool.
