Self-propelled vehicles that adjust the pitch of the vehicle during use are disclosed. The vehicle may include a suspension system position sensor and a control unit that adjusts a suspension element based at least in part on a signal from the suspension system position sensor. In some embodiments, the self-propelled vehicle may include an inclinometer for measuring the pitch of the terrain.

A controller for a baler, includes an ejecting position acquisition circuit, a prohibited position acquisition circuit, and a control circuit. The ejecting position acquisition circuit is configured to acquire an ejecting position at which an ejecting unit of the baler is configured to eject a bale of grass. The prohibited position acquisition circuit is configured to acquire a prohibited position. The control circuit is configured to control the ejecting unit to eject the bale at the ejecting position if the ejecting position is different from the prohibited position.

A grass management system includes a prohibition determination circuit and a baler. The prohibition determination circuit is configured to determine a prohibition position. The baler is configured to acquire the prohibition position from the prohibition determination circuit, and eject a bale of grass at a position except for the prohibition position.

A bale composition determination system comprising a baler configured to pick up crop material cut and lying on the ground in the form of a windrow and to form bales of the crop material. The system additionally includes one or more sensors configured to obtain electromagnetic reflectance information for the crop material. The system further includes a control system configured to receive the electromagnetic reflectance information for the crop material and to generate vegetation index values for the bales of crop material based on the electromagnetic reflectance information.

The disclosure relates to weighing a bale formed by a harvester such as a round baler. One or more load sensors located in the tailgate section of the harvester are used to obtain weights when the harvester contains a bale and when the harvester is empty. Other factors, including the slope of the surface on which the harvester is location, the size of the bale, the bale moisture, and the shape of the bale are used to adjust the calculated bale weight.

An agricultural material baling system comprises, in one example, a bale forming component configured to form a bale of agricultural material from a terrain, and a control system configured to determine that the bale is to be released from the baling system onto the terrain, determine that a current location of the baling system has a slope above a threshold, determine a different location, that is spaced apart from the current location, for releasing the bale onto the terrain, and provide an output indicative of the different location. In one example, the control system is configured to receive yield data indicative of a volume of agricultural material in a path of the baler and to control the baling system based on the yield data. In one example, the yield data is obtained from a raking operation that rakes the agricultural material into a windrow.

A baler comprises: a frame, including a forming chamber, configured to receive crops and to form a bale; a feeding assembly, configured to collect the crops from the ground and to feed the crops into the forming chamber; a tailgate, movable between a closed position, wherein the forming chamber is closed, and an open position, wherein the forming chamber is open to an external environment for discharging the bale; a control unit; a ramp, configured to lay down the bale on the ground and movable between a raised position and a discharge position, for allowing a release of the bale; a ramp sensor, responsive to a change of position of the ramp from the raised position to the discharge position and vice versa. The control unit is connected to the ramp sensor for assessing a release of the bale, responsive to a change of the ramp position from the raised position to the discharge position and, in succession, from the discharge position to the raised position. The control unit comprises a timer.

An agricultural crop baler having a frame, wheels, tailgate, baling chamber, ramp, and an arm attached to the frame and movable between a first position in which the arm extends along a first lateral side of the bale ejection path and does not intersect the bale ejection path, and a second position in which the arm extends along the first lateral side of the bale ejection path and intersects the bale ejection path. The baler also includes an actuator operatively connected between the frame and the arm and configured to move the arm between the first and second positions, and a control system configured to operate the actuator. A method is also provided, in which a baler arm contacts a side of the bale to generate a force on the bale in a direction transverse to the forward direction.
