MOWER KNIVES WITH STAGGERED SERRATIONS Abstract of the Disclosure A double knife, that can be unitary or consisting of two separate knives, is configured to be mounted on a reciprocating bar of a reciprocating knife. The double knife comprises two cutting sections extending in a forward direction which is perpendicular to the direction of reciprocation. Each of the cutting sections has two lateral faces with serrated cutting edges. The serrations of one cutting section are offset in the forward direction from the serrations of the other cutting section. The two cutting sections can be provided on a single double knife or on separate knives. Preferably, the stroke of the knives is larger than their width, such that a guard finger interacts with two cutting sections and the wear of the guard finger is reduced, since each of the cutting sections interacts with different locations of the guard finger. 150 f15210 130 132 12124 112- 106 130 132 122 130 12 1421412 112__, 126 130 1321418 1428 Fig. 3 |
