US Patent 11051456 Bale weight measurement and control system using liftgate

A bale holder is actuated to hold a bale in a lift gate of a baler. Lift gate actuators are then actuated to lift the gate, while it is holding the bale. A gate position sensor senses the position of the lift gate, and a force detector detects a force that is used in order to support the gate in the detected position. Bale weight generation logic then generates a bale weight based on the sensed lift gate position and the detected force. A control signal is generated based on the bale weight.
