ABSTRACT:
Two embodiments of mowing machines wherein the cutters are resiliently deflectable to within a guard. In both embodiments, the frame of the mowing machine is connected to a tractor and extends laterally therefrom, the mowers being powered from the power take-off of the tractor by a train of gears, shafts and connecting universal joints. In one embodiment, the mowers rotate about vertical axes with the cutters being rotated on elongated resilient shafts which are also rotated about a common main axis from which they are spaced. The cutters are supported near the ground by holders which permit resilient deflection of the cutters' shafts into guards supported by the mowers when the cutters encounter obstacles or otherwise are subjected to forces which cause them to deflect. In the other embodiment, the cutters are mounted on an endless member such as a chain which runs around laterally spaced apart wheels such as sprockets which are mounted on carrier plates which are connected by a rod which is spring-biased. The endless member of the cutter is thus deflectable whereby it is withdrawn within a guard structure when encountering obstacles and like deflecting forces. Tines rotate over the cutters in both embodiments about vertical axes in the first and about a horizontal axis in the second to move cut crop to the rear into a swath, swath-forming members being supported to extend to the rear in the first embodiment.
