ABSTRACT:
An agricultural mower including a parallel linkage suspension mechanism for the cutter assembly, the suspension mechanism including swing arms which in the use position are substantially vertically oriented, enabling the cutter assembly, upon striking an object, to respond by moving quickly rearwardly relative to the forwardly traveling main frame, and then, as the pendulum action continues, to elevate the cutter assembly above the obstruction to a clearing height. In the use position, the cutter bar and guards are directed down and forward defining the lowest and leading part of the cutter assembly.
