A programmable utility vehicle assembly 10 comprises a carriage 20 for moving over a plot, and a mobile transceiver 30 attached to the carriage 20 for transmitting a signal. The assembly 10 includes a power unit 22 for driving the carriage 20 over the plot, and a steering unit 24 for steering the carriage 20 over the plot. The assembly 10 further includes a plurality of locating stations 40 each having a stationary transceiver 42 for receiving a signal from the mobile transceiver 30 and transmitting a return signal to the mobile transceiver 30. The assembly 10 is characterized by a central processing unit 60 (CPU) on the carriage 20 for preprogramming a desired vehicle path having a counter 62 for counting two way propagation time between the mobile transceiver 30 and said remote locating stations 40 to determine said vehicle location and guide said vehicle along the programmed path.
