1. A beam stageloader bootend comprising:
at least one lift actuator configured to raise or lower a portion of the bootend;
a pressure sensor configured to output a pressure sensor output signal related to a pressure within the at least one lift actuator; and
a controller connected to the pressure sensor and the at least one lift actuator, the controller including a non-transitory computer readable medium and a processor, the controller including computer executable instructions stored in the computer readable medium for controlling operation of the bootend to:
receive the pressure sensor output signal;
determine the pressure within the at least one lift actuator based on the pressure sensor output signal; and
generate a control signal for the at least one lift actuator to adjust the pressure within the at least one lift actuator based on the pressure within the at least one lift actuator.
