ABSTRACT:
A mowing apparatus of the reciprocating sickle type includes, as is conventional, guards projecting forward from an elongated frame member and a sickle bar assembly, including a plurality of knife sections, reciprocating parallel to the frame member with cutting edges of the knife sections and of the guards in a crop shearing relationship. Somewhat resilient holddown plates are rigidly secured to the frame member and have finger-like portions extending forward over the guards and defining, with the guards, a slot in which the sickle bar assembly reciprocates. Bridge-like adjusting clips each have a rear leg bearing on the frame member and a forward leg bearing downwards on a finger portion of the holddown plates. Clip retaining means are adjustable so as to vary the pressure of the forward leg of the clip on the holddown plate, to control the width of the slot between the holddown plate and the guard and thus the operating clearance between the knife sections and the guard ledger surfaces.
