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.

An agricultural baler having a baling chamber and a pre-compression chamber, wherein the pre-compression chamber is adapted to periodically form a slice of crop material and push the slice towards the baling chamber into a first segment of the baling chamber, the baling chamber has a plunger provided for reciprocally moving in the baling chamber thereby compressing slices of crop material into a bale, wherein at least one optical bale length sensor is provided in the baling chamber for measuring the length of the bale.

A baler including a binding system including a twine holder including a first rotary disk including a first clamping notch forming a first knot and a second clamping notch forming a second knot, the depth of the second notch being greater than that of the first notch, a retainer adjacent a periphery of the first rotary disk, a clamping plate cooperating with the retainer to hold the twines and a drive system rotating the first rotary disk to clamp twine located in at least one of the clamping notches against the retainer. The retainer applies a greater clamping force on the twines located in the first notch than those located in the second notch. When the twines are located in the second notch, the first rotary disk rotates the twines beyond an end of the clamping plate, thereby releasing the twines from the clamping plate and the retainer.

A strapping system for an agricultural implement includes a strap feeding assembly positioned on a first side of a baling chamber and a needle positioned on a second side of the baling chamber, opposite the first side. The system also includes a first slot disposed within a first material-facing surface of a rear wall of the baling chamber. The strap feeding assembly is configured to propel a strap through at least a portion of the first slot to the second side of the baling chamber, and the needle is configured to grip a portion of the strap and to move the portion of the strap from the second side of the baling chamber to the first side of the baling chamber to surround a material within the baling chamber with the strap.

A device and method for tracking and marking bailed forage material is provided. The moisture content of forage material entering the intake of a processing machine is measured prior to the forage material being transferred to a baling chamber of the machine. As the forage material passes through the machine, the locations of discrete portions or flakes of the forage material are linearly tracked so that each portion may receive pre-selected markings indicative of measured parameters of each portion. A plurality of sensor stations is incorporated within the machine to track the locations of the portions of material. After the forage material is baled, a marking station generates markings applied to each bale which corresponds to the observed parameters for the corresponding discrete portions. Observed parameters may include moisture content for each flake, an amount and type of conditioning inoculant applied to each flake, among others. Multiple markings can be applied to each bale to indicate moisture content for selected portions of the bale since moisture content may differ between flakes in the bale.

An agricultural baler including a main bale chamber, a plunger configured to compress crop material in the bale chamber, a plunger drive, and a plurality of needles. The plunger drive is drivingly coupled to the plunger. The plurality of needles are configured to deliver twine through the bale chamber. The agricultural baler further includes a pivoting latch system drivingly coupled to both the plunger drive and the needles. A knotter is activated by the needles moving to a predetermined position.

A baler including a bale chamber; a plunger to compress crop material in the bale chamber to form a bale; a plurality of knotters; a needle yoke with a plurality of needles to deliver a plurality of lower strands through the bale chamber to the plurality of knotters; a tucker arm shaft carrying a plurality of tucker arms to deliver a plurality of upper strands to the plurality of knotters; a driving shaft located above the bale chamber and extending in a traverse direction of the baler; wherein the tucker arm shaft extends parallel to the driving shaft; a tucker arm coupling device to covert the rotation of the driving shaft into a rotation of the tucker arm shaft; a needle coupling device to convert a rotation of the driving shaft into a movement of the needle yoke from a rest position to a twine delivery position and back.

A baler including a bale chamber; a plunger configured to compress crop material in the bale chamber in order to form a bale; a needle yoke with a plurality of needles configured to deliver twine through the bale chamber; a plurality of knotters configured to receive the twine from the plurality of needles; a bale length measurement and trigger device configured to measure the length of the bale in the bale chamber and to generate a trigger when a predetermined length is reached; a driving shaft located above the bale chamber and extending in a traverse direction of the baler; a needle coupling device between the driving shaft and the needle yoke, the needle coupling device being configured for moving the needle yoke from a rest position to a twine delivery position and back, when the bale length measurement and trigger device generates a trigger.

The invention discloses a knotter driven by double fluted disc. The knotter driven by double fluted disc comprises a small fluted disc, a knotter rack, a large fluted disc, a cutter arm assembled on the knotter rack, a knotter jaw and bill hook combined mechanism (R), a rope gripper driving mechanism (Q) and a rope gripper (J), wherein a composite fluted disc of traditional D-knotter is divided into the small fluted disc and the large fluted disc in the knotter driven by double fluted disc.

An agricultural baler includes a main bale chamber, needles, knotters, a triggering system, a knotter lock, a blow-off mechanism, and a monitoring system. The needles are coupled to the main bale chamber and thread twine around a formed bale. The knotters receive the twine from the needles and tie the twine. The triggering system is for activating the needles and the knotters. The knotter lock is a manual lock of the triggering system thereby preventing the needles and the knotters from being triggered. The blow-off mechanism directs a flow of air at the knotters and the needles. The monitoring system has a single sensor that provides signals indicating a normal operation of the knotters, and whether the knotter lock is engaged.
