ABSTRACT:
Apparatus for sensing moisture in crop material includes a probe mounted on a pickup of an agricultural baler for movement between a retracted position and an operative position. The probe has a pair of fingers arranged in a spaced apart relationship so that crop material picked up by the baler bridges the space between the fingers when the probe is in the operative position thus creating a signal path between the fingers. The moisture sensing apparatus also includes a cam roller carried on the pickup to move the probe from its retracted position to its operative position, and a computer connected to the probe to measure the conductance level of the crop material creating the signal path.
