1. A round baler for agricultural stem crop, comprising a plurality of compression elements;
- delivery elements;
a main drive for driving the compression and delivery elements;
drive means for connecting the main drive with the compression elements and the delivery elements;
a wrapping apparatus for binding the compressed bales with a binding means; and
at least one load sensor provided in the connecting drive means of the baler between the main drive and the compression elements of the baler for generating, in response to a load rate acting on a respective compression element reaching a predetermined magnitude, a control signal for effecting at least one of actuation of the wrapping apparatus and turning off of at least one of the delivery elements,wherein the main drive comprises two output shafts one of which drives the compression elements and another of which drives at least one of the delivery elements, and wherein the load sensor is associated with the one shaft, and the other shaft includes an overload clutch.
