A crop stripper drum has a series of axial rows of flexibly displaceable teeth (12) circumferentially spaced around the drum. At the roots of the teeth are bulbous openings (12b, 22a) formed in metal members, which may comprise the teeth (12) or be elements (21) separate therefrom. For flexibility, the teeth may be given root openings larger than the openings formed by said separate elements, thereby reducing their root widths, or they may be put in a resilient mounting (62) that increases the d...

A towed type crop sprayer for spraying a liquid agricultural chemical upon a standing crop includes a frame having a tank mounted thereon and having a horizontal transversely extending boom assembly thereon for supporting a spray device. A centrally located cylinder and piston unit and cable tensioning mechanism are operable to produce ready vertical adjustment of the boom assembly and spray device carried thereby. The tractor which tows the crop sprayer, and the crop sprayer, are provided with ...

A crop conditioner for crimping cut crops to enhance rapid drying. The conditioner includes two crimper roller members mounted to a frame. One roller member is radially movable with respect to the other and has a constant bias toward the stationary roller when under load. The conditioner includes a drive mechanism at each end for positive drive of both roller members from both ends. The biasing means permits independent radial motion of each end of the movable roller member.

A crop conditioner has a frame adapted to travel along the ground, an upstream pair of vertically spaced ribbed rollers to which is supplied a stream of crop to be conditioned, and a downstream pair of ribbed rollers downstream of the upstream pair. A drive counterrotates the upstream rollers at a predetermined speed and thereby takes in the crop stream, conditions it, and puts it out toward the downstream rollers. A drive also counterrotates the downstream rollers at a predetermined speed which...

An auger cutter, windrower and conditioner for standing and downed crops such as hay, or forage harvester crops such as corn, sorghum and cereals including a cutter auger with cutting teeth attached to an auger flight and a conveyor auger to move the cut crop to a central area or to either side of the cutter to be discharged as a windrow or as a mass of material, or to be fed to a second crop processing device such as a forage harvester. An improved relationship of the cutting augers and the con...

A crop cleaner comprising a generally parallel array of first and second rollers each first roller being scrolled and each second roller generally unscrolled, the first rollers alternating with second rollers with pairs of adjacent rollers being carried on frames with each frame being displaceable relative to an adjacent frame and a drive for independently rotating each pair of rollers.

A crop blower for a combine harvester. An elongated, tubular housing has a convex outer surface on a first side and a concave outer surface on a second side. There is a fan having a central shaft extending parallel to the housing and spaced-apart from the concave surface thereof. The fan has a plurality of groups of blades. Each group of blades has a plurality of spaced-apart blades which are generally parallel to the shaft and operatively connected thereto. There is a bearing support for the fa...

A crop harvesting machine comprises two or more separate storage compartments (5a,5b) and a mechanism (6) for diverting harvested crop between the storage compartments as the machine moves across a field. The machine may also include a GPS positioning system and a control system (1) for controlling the diverter (6) on the basis of the machine's position and a map of harvesting instructions. The machine may in addition or alternatively include sensors (8) to analyse properties of the crop as it i...

The invention relates to a crop store and to a mechanism for loading same. The crop store may have a movable wall and pressure indicating means. Also more than one compartment can be included in the crop store. The loading mechanism is compressing means, preferably a rotatable screw conveyor or a reciprocating piston, which communicates with the crop store via a supply channel.

A harvesting machine including a crop-cutting apparatus particularly for cutting the tops off a standing crop. The cutting apparatus includes a pair of rotatable knife discs rotatable on substantially vertical axes and having a slight overlap in cutting area. A pivoted vertically extending guide vane directs cut material toward one knife or the other. A drum is carried above each knife and rotates therewith. The drums have radially extending crop moving paddles thereon. Curved vertically extendi...
