A crop lifter auger is rotatably driven by a drive. The crop lifter auger has a first forward end and a second rear end. The drive drives the crop lifter auger at the first forward end. The first forward end of the crop lifter auger is pivotally mounted whereas the second rear end can be fixed into different positions.

A harvester having means for reducing its width for transport has a crop gathering table, and a harvester body portion connected to the gathering table by a vertical pivot. The harvester body portion can be swung about the pivot axis from a longitudinal working position to a transverse transport position to reduce the width of the harvester for transport.

A hay conditioner is provided with a crop deflecting baffle having an operative position for deflecting crops for deposit in a swath. Rearwardly converging deflector vanes are mounted on the baffle, preferably about halfway respectively between the transverse edges of the baffle and the center of the crop stream. Preferably, the angle of convergence of the vanes is less than that of the fixed side deflectors of the preferred windrowing apparatus.

A large round baler is provided with a crop take-up arrangement as well as a knife shaft ahead of the inlet of a baling chamber which carries knives that cooperate with blades of a first rotor to cut crop material into pieces before the first rotor delivers the crop directly into the baling chamber. A second rotor is provided between the take-up rotor and the first rotor shaft for narrowing the crop flow from that of the crop take-up arrangement to that of the first rotor. All of the rotors perf...

An agriculture sprayer for applying herbicides between crop rows while simultaneously applying root growth stimulants, fungicides, fertilizers and/or insecticides to plant rows. The sprayer includes a tool bar to which a plurality of adjustable primary spray hood assemblies are pivotally mounted so as to be vertically movable as well as adjustable in pitch angle from front to rear so that the assemblies will follow the terrain of a field being sprayed. The primary spray hood assemblies include d...

A crop header for a harvesting machine includes a frame, a reciprocating support coupled to the frame and a crop conveyor pivotally coupled to the reciprocating support.

A crop harvester header includes a plurality of intake and mowing drums mounted in side-by-side relationship to each other across the width of the header. Located to the rear of the intake and mowing drums for receiving crop delivered to the rear by them are a pair of slope conveyor drums respectively located on opposite sides of a longitudinal center plane of the header and at opposite sides of an inlet passage leading to feed rolls for introducing the crop into a chopper drum of the harvester....

The invention provides a method of improving the yield of a crop. The method comprises growing transgenic plants to produce a crop, the transgenic plants being able to metabolize at least one synthetic auxin. A synthetic auxin is applied to the plants at least once during their growth, the synthetic auxin being one that can be metabolized by the transgenic plants. Finally, the crop is harvested.

A residue coulter apparatus that cleanly severs and clears crop debris from a planting row, causing minimal disturbance to the soil. The residue coulter apparatus comprises a pair of flat discs each having a plurality of back swept shark type teeth extending about their periphery. The teeth include a double beveled cutting edge on the outer edge of the teeth adapted to sever residue from the field. The clearing discs are oriented substantially vertical to the ground. Two clearing discs are used ...

A method and apparatus for mechanically thinning crops, particularly those planted in rows. One or more crop thinning units are connected to the back of a tractor or other vehicle. Each of the units has the ability to sense plants and activate an arm which has a blade disposed thereon. An electronic control system enables data from several sensors to be evaluated such that plants may be selectively removed based on pre-established criteria. Sensors differentiate between weeds and plants, and mai...
