The pivoting action sickle drive has a low profile allowing incorporation in or below a floor of a header of a plant cutting machine to allow passage of cut plant material thereabout. The drive includes a substantially flat rotatable input element, and a drive arm connected eccentric thereto for eccentric rotation along an epicyclical path. The arm extends to a connection with a pivot arm of a pivot element that connects to a knife arm that drives a sickle knife assembly, such that the pivot element, knife arm and knife assembly will be reciprocatingly driven by the eccentric rotation of the drive arm. A second drive can oppositely drive a second sickle knife assembly, such that opposite forces generated by the drives will cancel. The drives can be packaged in a forwardly tapered or curved enclosure, and the pivot elements can be correspondingly shaped to streamline the drives.

Two-sided cleaning arrangements for an endless belt for an agricultural header are disclosed. An endless belt with a two-sided cleaning arrangement may include a crop carrying surface and first and second cleaning features disposed in first and second edge regions, respectively, of the endless belt. The first and second cleaning features may extend above or be recessed below the crop-carrying surface.

A boom mower attachment that moves a cutting mechanism in a first movement, a second movement, and a third movement by only using two motions of a single control and method of use thereof is provided. The boom mower may include a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. An implement control system including a control, at least one function switching mechanism, and an implement is also provided. Activation of the control is operative to move the implement in a first mode, a second mode, and a third mode by only using two motions of the control.

The cutter guard assembly includes a cutter bar assembly, a window frame, and a floor sheet. The cutter bar assembly has a cutter bar and a reciprocating knife assembly operatively connected to a knife drive. The window frame is rigidly attached to the cutter bar. The window frame includes an opening through which a knife arm of the reciprocating knife assembly extends through. The floor sheet extends rearwardly from the cutter bar and pivots relative to the window frame.

An improved cutter assembly for use with a header of an agricultural harvester is provided. The assembly includes a pair of oppositely directed knife blades or cutter bars and a center knife drive. A crank shaft drives both knife blades in linear reciprocating paths with no fore and aft movement. As a consequence, harmful fore and aft vibration is eliminated. The assembly is simple and durable in design, less susceptible to vibration-induced wear and tear, and comparatively simple to manufacture and repair.
