A harvesting machine may include a main frame, a rotor assembly rotatably coupled to the main frame, a top frame movably attached to the main frame forming a passageway for crop material between the top frame and the rotor assembly, a bottom frame movably attached to the top frame, a plurality of knives movably attached to the top and bottom frames, and an actuator operatively connected to one of the top frame and the bottom frames. The plurality of knives extends through slots in the top frame. The top and bottom frames and the plurality of knives are in a raised position when the actuator is in a first position. The top and bottom frames and the plurality of knives are in a lowered position when the actuator is in a second position, which enlarges the passageway and partially retracts the knives through the slots in the top frame.

Bale measuring method for a rectangular baler includes the steps of: measuring a movement of a binding material that is being tied around a bale; using the measured movement of the binding material to calibrate a measurement and calculation tool for measuring a movement of the bale in the baler and for calculating a length of the bale based on said measurement; determining the length of the bale using the calibrated measurement and calculation tool as the bale moves backward in the baler.

A bale identification assembly has a binding material with identification tags at spaced intervals is used by a knotter system to bind a formed bale. A read module with an antenna transmits interrogator signals and also receives authentication replies from identification tags. The bale identification assembly has a bale drop sensor with a paddle. As a completed bale passes through the discharge chute, the completed bale interacts with the paddle causing the bale drop sensor to activate. Activation of the bale drop sensor activates the antenna for a specified active cycle, and during its active cycle, the read module assigns any identification tag that is sensed to the completed bale that is leaving the discharge chute. A controller receives information from at least one crop sensor and/or bale sensor and associates the information about the completed bale with the identification tag on the completed bale.

A mistie detection system comprising a baler configured to form bales from crop material. The baler includes a least one baling chamber configured to compress crop material into bales and at least one knotter assembly configured to tie securement lines around the bales. The system additionally includes one or more image sensors mounted to the baler and configured to monitor one or more of the knotter assembly, the securement lines, and the bales. The system further includes a control system configured to receive image data from the image sensors to determine if a mistie event has occurred.

A baler twine tension measurement assembly including a displacement detector and elements defining a first twine path. The first twine path extends between a first location and a second location which is angularly displaceable with respect to the first location. The displacement detector operates to generate a signal indicative of the angular displacement of the second location with respect to the first location.

A controller receives information from at least one crop sensor and/or bale sensor and associates the information about the completed bale with the identification tag on the completed bale.

In one embodiment, an agricultural crop baler comprising: a supporting frame; a pressing chamber configured to receive a stuffer, the stuffer compressing the crop into the pressing chamber; and at least one positionally adjustable side wall forming part of the pressing chamber, the side wall being supported by the supporting frame and configured to vibrate upon movement of the stuffer.

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.
