Abstract
Drum mowers having flat L-shaped blades in which the vertical portions are spring mounted relative to the rotating drums of drum mowers are disclosed having a spring mounting providing yielding of the horizontal portion of the blade in both a vertical and horizontal direction when it strikes an obstruction and automatic return of the blade to its mowing position. The flat blades provide greater strength and less vertical obstruction than prior blades. In a preferred embodiment, the end cutting portions of the blades attached to adjacent drums of multiple drum mowers do not overlap adjacent discs and are twisted with respect to the flat horizontal portion so the sharpened leading edge is downward.
