A baler for agricultural crop has a pressing channel and a needle rocker pivotably arranged at the pressing channel about a rocker pivot axis arranged in a plane that is orthogonal to the longitudinal center axis of the pressing channel. A drive arrangement connected to the needle rocker pivots the needle rocker relative to the pressing channel. The needle rocker has tying needles that are moved through the pressing channel when the needle rocker is pivoted. The drive arrangement has a drive element, rotatably supported about a drive axis of rotation; a coupling device pivotably supported about a coupling pivot axis positioned stationarily relative to the pressing channel; and a drive lever with a first end eccentrically connected to the drive element and a second end connected to the coupling device. The coupling device is connected to the needle rocker spaced from the rocker pivot axis of the needle rocker.

A wrapping arrangement for an agricultural round baler includes a support frame and a wrapping mechanism including at least one wrap material feeding means mounted on the support frame. The at least one wrap material feeding means includes a supply of wrap material. At least one wrap material clamp and cutting device is operably mounted to the at least one wrap material feeding means, and a clamp mechanism is mounted proximate to the at least one wrap material clamp and cutting device. The clamp mechanism is adapted to clamp a free end of the wrap material by a biasing clamping force for pre-positioning the wrap material for functional operation with the wrapping mechanism.

An agricultural baler includes a pre-compression chamber having an outlet, and a main bale chamber adapted to receive crop from the pre-compression chamber. A plunger is reciprocally disposed within the main bale chamber, and includes a plurality of plunger slots which are structured and arranged to allow a plurality of needles to intermittently pass therethrough. The baler is characterized by a plunger cleaner which is structured and arranged to provide the dual functionality of: 1) cleaning the plunger slots, and 2) opening and closing the outlet of the pre-compression chamber.

A device for braking lines of tying twine, for agricultural machines, of the type of balers, round balers and the like. Such machines are provided with assemblies for tying bales of previously-cut agricultural products, of the type of grass, wheat, maize, hay, forage, and the like. The braking device comprises an electronic unit for controlling and managing at least one actuator (2) for moving at least one braking element (3), which is actuated by the electronic unit by way of the actuator (2), in order to retain at least partially at least one respective length of at least one line of twine (A), during its unreeling.

A device, method, and system for determining a moisture level of for an agriculture machine. receiving crop material in a chamber of the agriculture machine. Determine a humidity of the chamber of the agriculture machine using a first signal of a first sensor of a moisture sensor assembly. The first signal is representative of humidity inside the chamber. Determine a humidity of an operating environment external to the agriculture machine using a second signal of a second sensor of the moisture sensor assembly. The second signal is representative of the humidity of an ambient environment of the agriculture machine. Determine a moisture level of the crop material in the chamber of the agriculture machine using the humidity inside the chamber and the operating environment. Modify operation of the agriculture machine based at least in part on the moisture level of the crop material in the chamber.

A baler connectable to a tractor for providing round bales comprises: a baling chamber for receiving crops for forming the bale, the baling chamber being supported on a wheel axle; a conveying assembly, including a belt which at least partially delimits the baling chamber for imparting a rotating movement to the crops contained in the baling chamber; a pick-up device, configured for picking-up the crops from a field; a feeding system, configured for feeding the crops to the baling chamber; a binder, configured for binding a formed bale with a fastening element.

The twine comprises-includes a mixture of at least 95 wt. % polypropylene and at most 5 wt. % additives. The twine is characterized by up to 8% vol. smectic phase. The percentage of the smectic phase is characterized using X-Ray Diffractometry (XRD). The additives are selected from, impact modifier, polyethylene, pigment, and UV stabilizer. The twine is characterized by a ratio between a specific work to a relative stiffness, of between 40 to 55 [J*mm/KgF].

A wrapping assembly for an agricultural baler includes: a supply of wrapping material; a wrapping mechanism configured to wrap the wrapping material around a formed round bale; a protrusion inserter configured to insert a roll-reducing protrusion on a surface of the formed round bale; and a controller operably coupled to the wrapping mechanism and the protrusion inserter. The controller is configured to: output a wrap initiation signal to the wrapping mechanism so the wrapping mechanism begins wrapping the formed round bale; and output a protrusion insertion signal to the protrusion inserter so the roll-reducing protrusion is inserted on a surface of the formed round bale and is subsequently wrapped by wrapping material wrapped around the formed round bale by the wrapping mechanism.
