Abstract
An encoder is mounted upon a vehicle within a sealed, tubular housing. The encoder is mounted within the housing by a shock absorbing mount. Stub shafts extend from each end of the tubular housing which are co-axial and which are aligned with a direction of movement of the vehicle. The stub shafts are sturdy and carry a row follower upon them. The row follower contacts a path to be followed along the ground. At least one of the sturdy stub shafts are connected to the encoder by a shock absorbing, flexible coupling. The encoder translates signals by which the vehicle is guided along the path contacted by the row follower.
