<p>@ In a crop cutting apparatus having a cutterbar (20) and attached sickle sections (20A-20E), an integrated hold-down sickle guard protects the sickle sections (20A-20E) from damage and maintains them in proper spaced relation relative to complementary cutting edges for optimum cutting action. The hold-down sickle guard eliminates the need for separate sickle section hold-down plates positioned along the length of the cutterbar and provides a sickle section retaining arrangement of increased strength for every sickle section permitting the linearly arranged, coupled reciprocating sickle sections (20A-20E) to be held in close cutting cooperation with associated complementary cutting edges along the entire width of the cutterbar (20). The hold-down sickle guard includes integral upper and lower sections (14, 16) with a generally horizontal slot located therebetween within which a sickle section is movably positioned. In one embodiment, the upper portions (14A, 14B) of adjacent sickle guard assemblies are securely joined by a tie bar (24) for increased sickle guard strength, while in another ambodiment the upper portion of each sickle guard assembly includes a turned down portion (54) which contacts an adjacent sickle section and maintains it in close cutting cooperation with the lower portion of the sickle guard.</p> |
