Provided is a work vehicle capable of efficiently performing grass collecting work by decelerating a traveling machine body in a case where the size of a bale is large and a case where the pickup load of straw grass is large. The work vehicle includes a traveling machine body 1, a roll baler unit 2, a bale detection unit 31 configured to detect a size of the bale formed by the roll baler unit 2, a load detection unit 32 configured to detect a pickup load of straw grass in the roll baler unit 2, and a traveling control unit 17A capable of decelerating the traveling machine body 1 when a size of the bale is equal to or larger than a setting value B1 and when a pickup load is equal to or larger than a setting value L. A deceleration D2 is larger than a deceleration D1.

The present invention provides a package of a filter tow bale made of cellulose acetate packed with a packing material in a non-hermetic state, which can be stacked in multistage and in which tows in the same bale can be uniformly maintained. The package of the filter tow bale made of cellulose acetate is packed with the packing material in the non-hermetic state, in which the filter tow bale is tightened with the packing material in the package, the filter tow bale has a cubic shape or a rectangular parallelepiped shape with 800 to 1,400 mm in length, 800 to 1,150 mm in width, and 800 to 1,100 mm in height, and a packing initial pressure between a top surface of the filter tow bale and the packing material is 6.3 kPa or less.

A bale identification assembly includes binding material (52) used by a knotter system to bind a formed bale (14), the binding material (52) comprising identification tags (62) at spaced intervals along the binding material. A read module (66) transmits interrogator signals and also receives authentication replies from the identification tags. A position sensor is used to predict passage of identification tags (62) through the knotter mechanism and a bale length sensor provides a signal representing bale length. A controller receives signals from the bale length sensor and the position sensor and generates a signal to alter the length of the bale (14) by causing an additional flake to be added to the bale by the plunger (34) or the bale to be finished with fewer flakes to prevent the knotter system from tying a knot in the binding material such that the identification tag is positioned in a portion of the binding material used to form the knot.

An agricultural system includes a baler with a plunger and a sensor for sensing a plunger-related value; a vehicle including a power source operable to convey power to the plunger; and a CVT arranged to drive the plunger. In order to balance a fluctuating load of the plunger over the working cycle, an electronic control unit (ECU) is coupled to the sensor and to the CVT and is configured to receive the signal from the sensor and to cause the CVT to modify a gear ratio of the CVT based on the signal from the sensor and on a mathematical model defining a CVT gear ratio variation profile derived from an expected load applied by crop on the plunger over its operating cycle.

Disclosed are methods and systems for determining the amount of material contained in a windrow. In particular embodiments, the methods and systems are applicable to agricultural applications, and in particular to hay yield monitoring. Systems include a remote sensing technology to determine windrow height. Remote sensing methods can include ultrasonic sensors, optical sensors, and the like. Systems can provide real time yield data.

Method and device for tagging round bales during wrapping in plastic foil, using a stationary or mobile baler-wrapper. Each round bale is oriented with the circular end surfaces mainly vertically and layers of plastic foil is wrapped around the round bale by foil wrapping arms. At a point in time where at least one layer of plastic film remains to be wrapped, each round bale is tagged with an ID tag having an adhesive back-side surface, using a time controlled, pivotal tagging arm provided with a tag transferring member. The movement of said tagging arm is controlled by a computer, which synchronizes the movement of the tagging arm with the movement of the foil supplying arms. After tagging, at least one additional layer of plastic is wrapped around each round bale to protect the ID tag.

An agricultural baler system has a plunger, a bale chamber, a pre-compression chamber and a stuffer unit, for moving crop from the pre-compression chamber to the bale chamber. The stuffer unit includes a stuffer fork trigger mechanism, an actuator and a controller. The actuator is coupled to the stuffer fork trigger mechanism. The controller is in controlling connection with the actuator. The actuator is configured to arm the stuffer fork trigger mechanism by moving the actuator between a first position and a second position. The actuator is further configured to be held in the first position and/or the second position with substantially no energy use.

An agricultural baler. The agricultural baler includes a baling chamber including a first segment, a plunger, and a baling chamber. The agricultural baler further includes a controller and a pre-compression chamber configured for gathering crop material, periodically forming a slice of the crop material, and pushing the slice towards the baling chamber into the first segment of the baling chamber. The agricultural baler further includes a slice-presence-detecting sensor disposed in an upper region of the first segment of the baling chamber, the slice-presence-detecting sensor comprising an output operationally connected to the controller. The plunger is configured for reciprocally moving in the baling chamber to compress slices of crop material into a bale. The controller is configured for adjusting a synchronization between the periodically forming and pushing of the slice in the pre-compression chamber and the reciprocally moving of the plunger.

A device and method comprising a large square baler with a pre-comprssion chamber that accumulates hay and moves it into the compression chamber, one or more near infrared specrocopy (NIRS) sensors mounted near the top of the pre-compression chamber, a means to read inputs from the sensors only when the stuffer forks are moving hayfrom the pre-compression chamber into the main chamber and a processor to average multiple readings from the nirs sensors from that inteval.
