The square baler comprises a pick-up (22), a pre-compression chamber (20), a baling chamber (10), a loading mechanism for transferring each slice of crop from the pre-compression chamber (20) into the baling chamber (10) and a plunger (32). According to the invention the baler comprises at least one non-contact sensor (50, 52, 54, 56, 58, 60) that is provided in at least one of the walls (44, 45, 46, 47) of the pre-compression chamber (20) and/or of the input zone (64) of the baling chamber (10) to produce an output signal indicative of the density of the crop.
A mechanism is disclosed for applying tension to a bale in the bale case of an agricultural baler. Two elongate tension rails (51,52) are arranged along two opposing sides of the bale case (20). Each tension rail (51,52) is pivotally connected (53,54) at one end adjacent to the forward end of the bale case (20) and extends rearwards to allow the tension rails (51,52) to be selectively pivoted inwardly and outward relative to the bale travel axis (100). A positioner mechanism (70) is connected the tension rails (51,52) for simultaneously moving the tension rails inwards or outwards. Each tension rail (51,52) has an offset bend which divides the rail into two generally planar surfaces (83,85;84,86) that are inclined relative to one another. Two successive bale compression regions (L1,L2) are defined within the bale case, with the tension rails (51,52) converging more rapidly in the first than in the second.
An agricultural implement includes a hitch boom to which a pair of wing booms is pivotably connected. The wing booms are designed to fold forward from an extended position to a transport position. The wing booms are supported above a surface by wheels that provide the aforementioned support when the wing booms are in an extended position as well as the transport position. Maintaining surface contact of the wheels in both positions reduces the load placed on the hitch to which the hitch boom is coupled as well as the hitch boom itself. Multi-link draft links are connected between the hitch boom and the wing booms to provide support for the wing booms when the wing booms are in the extended position. The relative length of the draft links dictates how far the hitch telescopes when the wing booms are folded to the stowed or transport position.

A precision hoe opener assembly is provided with improved accuracy of seeding as well as improved control over the opener and packer wheel assemblies. The opener assembly includes a hydraulically-driven parallel linkage assembly, a lost motion linkage, a biasing member, a ground engaging tool, and a packer wheel. The design provides improved seeding accuracy, by compensating for changes in draft force caused by changes in terrain elevation.

A system and method for operating a ground working tool having attached thereto an implement includes a trip mechanism. The trip mechanism includes a generally horizontally oriented hydraulic cylinder configured to be biased into an extended position to engage the implement in a work position engaged to work the ground. Specifically, a link rod connects the hydraulic cylinder to a carrier to which the implement is attached. The link rod can be adjusted in length and has a generally small diameter, such that, upon extending into hydraulic cylinder when the implement impacts an obstruction, the link rod does not contact the hydraulic cylinder.
A fill tube and sensor assembly has a single electronic sensor to detect the level of product in a hopper of an agricultural implement relative to a fill line. The electronic sensor can be positioned at various heights relative to the fill tube to provide variability in the height of the fill line. The sensor provides a full level signal until product is drawn from the fill tube. Once the product is dispensed from the fill tube and into the general interior volume of the hopper, the single sensor provides an empty level signal that can be used to alert an operator of a diminished product supply or control operation of the farm implement.

The present planter unit, and planter implements using the present planter unit, include first and second discs and first and second pathways. The first and second discs may be generally planar and in a non-overlapping relation. As the planter unit is towed through a field, the first disc creates a first trench in the seedbed and the first pathway deposits a first material in the first trench. Subsequently, the second disc creates a second trench which is continuous with the first trench and partially fills the first trench. A second material is deposited in the second trench by the second pathway.
