An automatic differential locking system for a working vehicle having steerable front and rear wheels, which includes a selector for selecting a steering mode of the vehicle, an actuator for operating a differential locking mechanism, and a gate for sending a control signal to the actuator in response to a signal received from the selector. The gate is adapted to send a differential locking signal to the actuator upon receipt of a parallel steering mode signal from the selector. In response to the differential locking signal the actuator actuates the differential locking mechanism. Since differential revolutions of the wheels are limited at times of parallel steering, the vehicle is capable of accurate course revisions and alterations without slipping.

A fruit harvesting apparatus in which the positions of fruit are searched and detected by a television camera with a variable shooting direction. Both the television camera and a spot light emitting device, such as a laser, are varied in position and direction in accordance with instructions to locate a fruit. A movable fruit picker is then moved to the determined position of the fruit and operated to pick the fruit.

A multistage change-speed apparatus for a tractor has a running-travel-system change-speed gearing apparatus, a planetary gearing reduction apparatus operatively connected to that apparatus, an intermediary transmission shaft driven by this apparatus, a speed-reduction shaft disposed beneath that shaft, a bevel pinion shaft disposed in parallel with this shaft, an auxiliary change-speed gearing apparatus disposed between these two shafts, and a differential operatively connected to that apparatus. The planetary gearing reduction apparatus is shiftable between the operative state and the inoperative state.
