A system for sensing and indicating the angle at which a vehicle-carried implement is inclined to a horizontal line, including a transmitter mounted on the implement and having a pendulum swingable in a housing, said housing being pivotable by remote control with respect to said implement. The transmitter further has light radiating and light sensing means variably screened by a shield on said pendulum to produce a signal depending on the inclination from the vertical of the pendulum housing, and thus characterizing deviation or correspondence between the actual implement inclination and the desired implement inclination, which is adjustable by pivoting the pendulum housing.
